| mplayer is a movie player for LINUX (runs on many other Unices and non-x86 CPUs, see the documentation). It plays most MPEG/VOB, AVI, ASF/WMA/WMV, RM, QT/MOV/MP4, OGG/OGM, VIVO, FLI, NuppelVideo, yuv4mpeg, FILM and RoQ files, sup- ported by many native, XAnim, and Win32 DLL codecs. You can watch VideoCD, SVCD, DVD, 3ivx, DivX 3/4/5 and even WMV movies, too (without using the avifile library). |
| Another great feature of MPlayer is the wide range of sup- ported output drivers. It works with X11, XV, DGA, OpenGL, SVGAlib, fbdev, AAlib, DirectFB, but you can also use GGI, SDL (and this way all their drivers), VESA (on every VESA compatible card, even without X11), some low level card-specific drivers (for Matrox, 3Dfx and ATI) and some hardware MPEG decoder boards, such as the Siemens DVB, DXR2 and DXR3/Hollywood+. Most of them support soft- ware or hardware scaling, so you can enjoy movies in fullscreen. |
| MPlayer has an onscreen display (OSD) for status informa- tion, nice big antialiased shaded subtitles and visual feedback for keyboard controls. European/ISO 8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and Korean fonts are supported along with 10 subtitle formats (Mi- croDVD, SubRip, SubViewer, Sami, VPlayer, RT, SSA, AQTi- tle, JACOsub and our own: MPsub) and DVD subtitles (SPU streams, VobSub and Closed Captions). |
| mencoder (MPlayer's Movie Encoder) is a simple movie en- coder, designed to encode MPlayer-playable movies (see above) to other MPlayer-playable formats (see below). It encodes to DivX4, XviD, one of the libavcodec codecs and PCM/MP3/VBRMP3 audio in 1, 2 or 3 passes. Furthermore it has stream copying abilities, a powerful plugin system (crop, expand, flip, postprocess, rotate, scale, noise, rgb/yuv conversion) and more. |
| gmplayer is MPlayer with a graphical user interface. It has the same options as MPlayer. |
| Also see the HTML documentation! |
| Every 'flag' option has a 'noflag' counterpart, e.g. the opposite of the -fs option is -nofs. |
| You can put all of the options in a configuration file which will be read every time MPlayer is run. The sys- tem-wide configuration file 'mplayer.conf' is in your con- figuration directory (e.g. /etc/mplayer or /usr/local/etc/ mplayer), the user specific one is '~/.mplayer/config'. User specific options override system-wide options and op- tions given on the command line override either. The syn- tax of the configuration files is 'option=<value>', every- thing after a '#' is considered a comment. Options that work without values can be enabled by setting them to 'yes' or '1' and disabled by setting them to 'no' or '0'. Even suboptions can be specified in this way. |
|
EXAMPLE: # Use Matrox driver by default. vo=xmga # I love practicing handstands while watching videos. flip=yes # Decode/encode multiple files from png, # start with mf://filemask mf=type=png:fps=25 |
| You can also write file-specific configuration files. If you wish to have a config file for a file called 'movie.avi', create a file named 'movie.avi.conf' with the file-specific options in it and put it in ~/.mplayer or in the same directory as the file. |
|
NOTE: MPlayer has a fully configurable, command driven, control layer which allow you to control MPlayer using keyboard, mouse, joystick or remote control (using lirc). The default configuration file for the input system is ~/.mplayer/input.conf but it can be overriden using the -input conf option. These keys may/may not work, depending on your video out- put driver. |

| -autoq <quality> (use with -vf pp) |
| Dynamically changes the level of postprocessing de- pending on available spare CPU time. The number you specify will be the maximum level used. Usual- ly you can use some big number. You have to use -vf pp without parameters in order to use this. |
| -autosync <factor> |
| Gradually adjusts the A/V sync based on audio delay measurements. Specifying -autosync 0, the default, will cause frame timing to be based entirely on au- dio delay measurements. Specifying -autosync 1 will do the same, but will subtly change the A/V correction algorithm used. An uneven video frame rate in a movie which plays fine with -nosound can often be helped by setting this to an integer value greater than 1. The higher the value, the closer the timing will be to -nosound. Try -autosync 30 to smooth out problems with sound drivers which do not implement a perfect audio delay measurement. With this value, if large A/V sync offsets occur, they will only take about 1 or 2 seconds to settle out. This delay in reaction time to sudden A/V offsets should be the only side-effect of turning this option on, for all sound drivers. |
| -benchmark |
|
Prints some statistics on CPU usage and dropped frames at
the end. Use in combination with -nosound and -vo null for
benchmarking only the video codec. NOTE: With this option MPlayer will also ignore frame duration when playing only video (you can think of that as infinite fps). |
| -edl <filename> |
| Enables edit decision list (EDL) actions during playback. Video will be skipped over and audio will be muted and unmuted according to the entries in the given file. See DOCS/documentation.html#edl for details on how to use this. |
| -edlout <filename> |
| Creates a new file and writes edit decision list (EDL) records to that file. During playback, when the user hits 'i', an entry to skip over the last two seconds of playback will be written to the file. This provides a starting point from which the user can fine-tune EDL entries later. See DOCS/documentation.html#edl for details. |
| -enqueue (GUI only) |
| Enqueue files given on the command line in the playlist instead of playing them immediately. |
| -fixed-vo (BETA CODE!) |
| Enforces a fixed video system for multiple files (one (un)initialisation for all files). Therefore only one window will be opened for all files. Cur- rently the following drivers are fixed-vo compli- ant: gl2, mga, svga, x11, xmga, xv and xvidix. |
| -framedrop (also see -hardframedrop) |
| Skip displaying some frames to maintain A/V sync on slow systems. Video filters are not applied to such frames. For B frames even decoding is skipped completely. |
| -h, -help, --help |
| Show short summary of options. |
| -hardframedrop |
| More intense frame dropping (breaks decoding). Leads to image distortion! |
| -identify |
| Show file parameters in easy parsable format. The wrapper script TOOLS/midentify suppresses the other MPlayer output and (hopefully) shellescapes the filenames. |
| -input <commands> |
| This option can be used to configure certain parts of the input system. Paths are relative to ~/ .mplayer/. |
|
NOTE: Autorepeat is currently only supported by joy- sticks. Available commands are: |
| conf=<file> |
| Read alternative input.conf. If given without pathname, ~/.mplayer is assumed. |
| ar-delay |
| Delay in msec before we start to autorepeat a key (0 to disable). |
| ar-rate |
| How many key presses per second when we au- torepeat. |
| keylist |
| Prints all keys that can be bound. |
| cmdlist |
| Prints all commands that can be bound. |
| js-dev |
| Specifies the joystick device to use (de- fault is /dev/input/js0). |
| file |
|
Read commands from the given file. Mostly useful with a
fifo. NOTE: When the given file is a fifo MPlayer opens both ends so you can do several 'echo "seek 10" > mp_pipe' and the pipe will stay valid. |
| -lircconf <file> |
| Specifies a configuration file for LIRC (Linux In- frared Remote Control, see http://www.lirc.org) if you don't like the default ~/.lircrc. |
| -list-options |
| Prints out all the available options. |
| -loop <number> |
| Loops movie playback <number> times. 0 means for- ever. |
| -menu (BETA CODE) |
| Turn on OSD menu support. |
| -menu-cfg <file> (BETA CODE) |
| Use an alternative menu.conf. |
| -menu-root <value> (BETA CODE) |
| Specify the main menu. |
| -nojoystick |
| Turns off joystick support. Default is on, if com- piled in. |
| -nolirc |
| Turns off LIRC support. |
| -nomouseinput |
| Disable mouse button press/release input (mozplay- erxp's context menu relies on this option). |
| -nortc |
| Turns off usage of the Linux RTC (real-time clock - /dev/rtc) as timing mechanism. |
| -playlist <file> |
|
Play files according to a playlist (1 file per row or Winamp
or ASX format). NOTE: This option is considered an entry so options found after it will apply only to the elements of this playlist. |
| -quiet |
| Don't display the status messages. With this op- tion the status line (i.e. A: 0.7 V: 0.6 A-V: 0.068 ...) will not be displayed. It's particulary useful when your terminal does not understand car- riage return (i.e. r) like the XEmacs one. |
| -really-quiet |
| Display even less output and status messages. |
| -shuffle |
| Play files in random order. |
| -skin <skin directory> (GUI only) (BETA CODE) |
| Load skin from the given directory (WITHOUT path name). |
| EXAMPLE: |
| -skin fittyfene |
| tries Skin/fittyfene. It first checks /usr/local/share/mplayer/ and afterwards ~/.mplayer/. |
| -slave |
| This option switches on slave mode. This is in- tended for use of MPlayer as a backend to other programs. Instead of intercepting keyboard events, MPlayer will read simplistic command lines from its stdin. |
| -softsleep |
| Uses high quality software timers. As precise as the RTC without requiring special privileges. Comes at the price of higher CPU consumption. |
| -speed <0.01-100> |
| Set playback speed rate. |
| -sstep <sec> |
| Specifies seconds between displayed frames. Useful for slideshows. |
| -use-stdin |
| The standard input (aka. stdin) will be used to read data instead of key events. If you open /dev/stdin (or the equivalent on your system), use stdin in a playlist or intend to read from stdin later on via the openfile or openlist commands you need this option. |
| -aid <id> (also see -alang option) |
| Select audio channel [MPEG: 0-31 AVI/OGM: 1-99 ASF/ RM: 0-127 VOB(AC3): 128-159 VOB(LPCM): 160-191 MPEG-TS 17-8190]. MPlayer prints the available IDs when running in verbose (-v) mode. When playing an MPEG-TS stream, MPlayer/Mencoder will use the first program (if present) with the chosen audio stream. |
| -alang <two letter country code> (also see -aid option) |
| Works only for DVD playback. It selects the DVD audio language and always tries to play audio streams whose language matches the given code. For the list of available languages, use with the -v option and look at the output. |
| EXAMPLE: |
| -alang hu,en |
| Plays Hungarian and falls back to English if Hungarian is not available. |
| -audio-demuxer <number> (-audiofile only) |
| Force audio demuxer type for -audiofile. Give the demuxer ID as defined in demuxers.h. Use -au- dio-demuxer 17 to force .mp3 detection. |
| -audiofile <filename> |
| Play audio from an external file (WAV, MP3 or Ogg Vorbis) while viewing a movie. |
| -audiofile-cache <kBytes> |
| Enables caching for the stream used by -audiofile, using the specified amount of memory. |
| -bandwidth <value> |
| Specify the maximum bandwidth for network streaming (for servers that are able to send content in dif- ferent bitrates). Useful if you want to watch live streamed media behind a slow connection. |
| -cdrom-device <path to device> |
| Override default CDROM drive name /dev/cdrom. |
| -cache <kBytes> |
| This option specifies how much memory (in kBytes) to use when precaching a file/URL. Especially use- ful on slow media (default is -nocache). |
| -cdda <option1:option2> |
|
This option can be used to tune the CD Audio read- ing
feature of MPlayer. Available options are: |
| speed=<value> |
| set CD spin speed |
| paranoia=<0-2> |
| set paranoia level |
|
0: disable checking 1: overlap checking only (default) 2: full data correction and verification |
| generic-dev=<value> |
| use specified generic SCSI device |
| sector-size=<value> |
| atomic read size |
| overlap=<value> |
| force minimum overlap search during verifi- cation to <value> sectors. |
| toc-bias |
| Assume that the beginning offset of track 1 as reported in the TOC will be addressed as LBA 0. Some Toshiba drives need this for getting track boundaries correct. |
| toc-offset=<value> |
| Add <value> sectors to the values reported when addressing tracks. May be negative. |
| (no)skip |
| (never) accept imperfect data reconstruc- tion. |
| -channels <number> |
| Change the number of playback channels, defaults to '2' if not specified. If the number of output channels is bigger than the number of input chan- nels empty channels are inserted (unless mixing from mono to stereo, then the mono channel is re- peated in both output channels). If the number of output channels is smaller than the number of input channels, results depend on the audio decoder (-afm). MPlayer asks the decoder to decode the au- dio into as many channels as specified. Now it's up to the decoder to fulfill the requirement. If the decoder outputs more channels than requested, the exceeding channels are truncated. This is usu- ally only important when playing videos with AC3 audio (like DVDs). In that case liba52 does the decoding by default and correctly downmixes the au- dio into the requested number of channels. |
|
NOTE: This option is honored by codecs (AC3 only) filters (surround) and ao drivers (OSS at least). Available options are: |
| 2 |
| Stereo |
| 4 |
| Surround |
| 6 |
| Full 5.1 |
| -chapter <chapter id>[-<end chapter id>] |
| Specify which chapter to start playing at. Option- ally specify which chapter to end playing at (de- fault: 1). Examples can be found below. |
| -csslib <filename> |
| (old-style DVD option) This option is used to over- ride the default location of libcss.so. |
| -demuxer <number> |
| Force demuxer type. Give the demuxer ID as defined in demuxers.h. Use -demuxer 17 to force .mp3 de- tection. |
| -dumpaudio (MPLAYER only) |
| Dumps raw compressed audio stream to ./stream.dump (useful with mpeg/ac3). |
| -dumpfile <filename> (MPLAYER only) |
| Specify which file MPlayer should dump to. Should be used together with -dumpaudio / -dumpvideo / -dumpstream. |
| -dumpstream (MPLAYER only) |
| Dumps the raw stream to ./stream.dump. Useful when ripping from DVD or network. |
| -dumpvideo (MPLAYER only) |
| Dump raw compressed video stream to ./stream.dump (not very usable). |
| -dvbin <options> |
| Pass the following parameters to the DVB input mod- ule, in order to override the default ones: |
| card=<1-4> |
| Specifies using card number 1-4 (default: 1). |
| file=<file> |
| Instructs MPlayer to read the channels list from <file>. |
| type=<SAT|TER|CBL> |
| Specifies that the card type is SATellite, TERrestrial or CaBLe. If not specified the type will be autodetected. |
| -dvd-device <path to device> |
| Override default DVD device name /dev/dvd. |
| -dvdangle <angle id> |
| Some DVD discs contain scenes that can be viewed from multiple angles. Here you can tell MPlayer which angles to use (default: 1). Examples can be found below. |
| -dvdauth <DVD device> |
| (old-style DVD option) Turns on DVD authentication using the given device. |
| -dvdkey <CSS key> |
| (old-style DVD option) When decoding a VOB file copied undecrypted from DVD, this option gives the CSS key needed to decrypt the VOB (the key is printed when authenticating with the DVD drive us- ing -dvdauth). |
| -forceidx |
|
Force rebuilding of INDEX. Useful for files with broken
index (desyncs, etc). Seeking will be pos- sible. You can
fix the index permanently with MEn- coder (see the
documentation). NOTES: You can only use this option if the underly- ing media supports seeking (i.e. not with stdin, pipe, etc). |
| -fps <value> |
| Override video framerate (if value is wrong/missing in the header) (float number). |
| -frames <number> |
| Play/convert only first <number> frames, then quit. |
| -hr-mp3-seek (MP3 only) |
| Hi-res mp3 seeking. Default is: enabled when play- ing from external MP3 file, as we need to seek to the very exact position to keep A/V sync. It can be slow especially when seeking backwards - it has to rewind to the beginning to find the exact frame. |
| -idx (also see -forceidx) |
|
Rebuilds INDEX of the AVI if no INDEX was found, thus
allowing seeking. Useful with broken/incom- plete downloads,
or badly created AVIs. NOTES: You can only use this option if the underly- ing media supports seeking (i.e. not with stdin, pipe, etc). |
| -ipv4-only-proxy |
| Skip the proxy for IPv6 addresses. It will still be used for IPv4 connections. |
| -mc <seconds/frame> |
| Maximum A-V sync correction per frame (in seconds). |
| -mf <option1:option2:...> |
|
Used when decoding from multiple PNG or JPEG files. Available options are: |
| w=<value> |
| width of the output (autodetect) |
| h=<value> |
| height of the output (autodetect) |
| fps=<value> |
| fps of the output (default: 25) |
| type=<value> |
| type of input files (available types: jpeg, png, tga, sgi) |
| -ni (AVI only) |
| Force usage of non-interleaved AVI parser (fixes playing of some bad AVI files). |
| -nobps (AVI only) |
| Do not use average byte/sec value for A-V sync (AVI). Helps with some AVI files with broken head- er. |
| -noextbased |
| Disables filename-extension based demuxer selec- tion. By default, when file type (demuxer) cannot be detected reliably (the file has no header or it is not reliable enough), the filename extension is used to select demuxer. It always falls back to content-based demuxer selection. |
| -passwd <password> (see -user option too) |
| Specify password for http authentication. |
| -prefer-ipv4 |
| Use IPv4 on network connections. Falls back to IPv6 automatically. |
| -prefer-ipv6 |
| Use IPv6 on network connections. Falls back to IPv4 automatically. |
| -rawaudio <option1:option2:...> |
|
This option lets you play raw audio files. It may also be
used to play audio CDs which are not 44KHz 16Bit stereo. Available options are: |
| on |
| use raw audio demuxer |
| channels=<value> |
| number of channels |
| rate=<value> |
| rate in samples per second |
| samplesize=<value> |
| sample size in byte |
| format=<value> |
| fourcc in hex |
| -rawvideo <option1:option2:...> |
|
This option lets you play raw video files. Available options are: |
| on |
| use raw video demuxer |
| fps=<value> |
| rate in frames per second, default 25.0 |
| sqcif|qcif|cif|4cif|pal|ntsc |
| set standard image size |
| w=<value> |
| image width in pixels |
| h=<value> |
| image height in pixels |
| y420|yv12|yuy2|y8 |
| set colorspace |
| format=<value> |
| colorspace (fourcc) in hex |
| size=<value> |
| frame size in Bytes |
| -rtsp-stream-over-tcp |
| Used with 'rtsp://' URLs to specify that the re- sulting incoming RTP and RTCP packets be streamed over TCP (using the same TCP connection as RTSP). This option may be useful if you have a broken In- ternet connection that does not pass incoming UDP packets (see http://www.live.com/mplayer/). |
| -sb <byte position> (see -ss option too) |
| Seek to byte position. Useful for playback from CDROM images / .VOB files with junk at the begin- ning. |
| -srate <Hz> |
| Forces the given audio playback rate, changing video speed to keep a-v sync. MEncoder passes this value to lame for resampling. |
| -ss <time> (see -sb option too) |
| Seek to given time position. |
| EXAMPLE: |
| -ss 56 |
| seeks to 56 seconds |
| -ss 01:10:00 |
| seeks to 1 hour 10 min |
| -tsprog <1-65534> |
| When playing an MPEG-TS stream, you can specify with this option which program (if present) you want to play. Can be used with -vid and -aid. |
| -tv <option1:option2:...> |
| This option tunes various properties of tv-capture module. For watching TV with MPlayer, use 'tv://' or 'tv://<channel_number>' or even 'tv://<chan- nel_name> (see option channels for channel_name be- low) as a movie URL. |
|
NOTE: MPlayer doesn't accept colons so type dots instead in the device ID (e.g. hw.0,0 instead of hw:0,0). Be advised that although you can select any sam- plerate when using ALSA, the LAME audio codec is able to encode only the 'standard' samplerates. You'll get an .avi file with no sound when you choose an odd samplerate and use this codec. Available options are: |
| noaudio |
| no sound |
| driver=<value> |
| available: dummy, v4l, v4l2, bsdbt848 |
| device=<value> |
| Specify other device than the default /dev/ video0. |
| input=<value> |
| Specify other input than the default 0 (Television) (see output for a list) |
| freq=<value> |
| Specify the frequency to set the tuner to (e.g. 511.250). Not compatible with chan- nels parameter. |
| outfmt=<value> |
| output format of the tuner (yv12, rgb32, rgb24, rgb16, rgb15, uyvy, yuy2, i420) |
| width=<value> |
| width of the output window |
| height=<value> |
| height of the output window |
| fps=<value> |
| framerate at which to capture video (frames per second) |
| buffersize=<value> |
| maximum size of the capture buffer in megabytes (default: dynamical) |
| norm=<value> |
| available: PAL, SECAM, NTSC. For v4l2 use the normid option below. |
| normid=<value> |
| v4l2 only. See MPlayer output for a list of available TV norms. |
| channel=<value> |
| Set tuner to <value> channel. |
| chanlist=<value> |
| available: europe-east, europe-west, us-bcast, us-cable, etc |
| channels=<chan- nel>-<name>,<channel>-<name>,... |
| Set names for channels. Use _ for spaces in names (or play with quoting ;-). The channel names will then be written using OSD, and the commands tv_step_channel, tv_set_channel and tv_last_channel will then be usable using a remote (see lirc). Not compatible with frequency parameter. Warning: The channel number will then be the position in the 'channels' list, begin- ning with 1. Example: use tv://1, tv://2, tv://TV1, tv_set_channel 1, tv_set_channel 2, tv_set_channel TV1, etc. |
| [brightness|con- trast|hue|saturation]=<-100-100> |
| set the color equalizer on the video card. |
| audiorate=<value> |
| set audio capture bitrate |
| forceaudio |
| capture audio even if there are no audio sources reported by v4l |
| alsa |
| capture from ALSA |
| amode=<0-3> |
| choose an audio mode: |
|
0: mono 1: stereo 2: language 1 3: language 2 |
| forcechan=<1-2> |
| By default, the count of recorded audio channels is determined automatically by querying the audio mode from the tv card. This option allows to force stereo/mono recording regardless of the amode option and the values returned by v4l. This can be used for troubleshooting when the tv card is unable to report the current audio mode. |
| adevice=<value> |
| set an audio device |
|
/dev/... for OSS hardware ID for ALSA |
| audioid=<value> |
| choose an audio output of the capture card, if it has more of them |
| [volume|bass|treble|bal- ance]=<0-65535> |
| [volume|bass|treble|bal- ance]=<0-100> |
| These options set parameters of the mixer on the video capture card. They will have no effect, if your card doesn't have one. For v4l1, 0-65535 is a valid range. For v4l2, the valid range is 0 to 100, and 50 maps to the default value of the control, as reported by the driver. |
| immediatemode=<bool> |
| A value of 0 means capture and buffer audio and video together (default for MEncoder). A value of 1 (default for MPlayer) means to do video capture only and let the audio go through a loopback cable from the TV card to the soundcard. |
| mjpeg |
| Use hardware mjpeg compression (if the card supports it). When using this option, you do not need to specify the width and height of the output window, because MPlayer will determine it automatically from the decima- tion value (see below). |
| decimation=<1,2,4> |
| choose the size of the picture that will be compressed by hardware mjpeg compression: |
|
1: full size 704x576 PAL 704x480 NTSC 2: medium size 352x288 PAL 352x240 NTSC 4: small size 176x144 PAL 176x120 NTSC |
| quality=<0-100> |
|
choose the quality of the jpeg compression (quality < 60 recommended for full size) |

|
NOTE: See -fstype help for a full list of available modes. |
| -geometry x[%][:y[%]] or [WxH][+x+y] |
| Adjust where the output is on the screen initially. The x and y specifications are in pixels measured from the top-right of the screen to the top-right of the image being displayed, however if a percent- age sign is given after the argument it turns the value into a percentage of the screen size in that direction. It also supports the standard option format to the standard X -geometry option. Be aware that the window size is changed to fit the aspect of the movie. If you want to disable this behaviour please use -noaspect. The values given must be integers. |
| Note: This option is only supported by vo x11, xm- ga, xv, xvmc, xvidix, directx and tdfxfb. |

| Specify a priority list of video codecs to be used, according to their codec name in codecs.conf. Use a '-' before the codec name to omit it. |
|
NOTE: See -vc help for a full list of available codecs. If the list has a trailing ',' it will fallback to codecs not listed. |
| EXAMPLE: |

| -vfm <driver1,driver2,...> |
| Specify a priority list of video codecs to be used, according to their names in codecs.conf. It falls back to default if none is ok. |
|
NOTE: If libdivxdecore support was compiled in, then odi- vx and divx4 now contains just the same DivX4 codec, but different APIs to reach it. For differ- ence between them and when to use which, check the DivX4 section in the documentation. See -vfm help for a full list of available drivers. |
| EXAMPLE: |

| Scale image to y height (if sw/hw scaling avail- able). Disables aspect calculations. |
| -zoom |
| Allow software scaling, where available. Could be used to force scaling with -vf scale. |
|
NOTE: -vf scale will IGNORE options -x / -y / -xy / -fs / -aspect without -zoom. |
| Video filter are plugins that allow you to modify the video stream and its properties. The syntax is: |
| -vf <filter1[=options],filter2,...> |
| Setup a chain of video filters. |
| -vop <...,filter3[=options],filter2,filter1> (OB- SOLETE) |
| Setup a chain of video filters, to be applied in reverse order. Deprecated in favor of -vf. |
| The parameters are optional and if omitted, some of them are set to default values. Use '-1' to keep the default value. Parameters w:h means width x height in pixels, x:y means x;y position counted from the upper left corner of the bigger image. To get a full list of available fil- ters, see -vf help. |
| Available filters are: |
| crop[=w:h:x:y] |
| Crops the given part of the image and discards the rest. Useful to remove black bands from widescreen movies. |
| w,h |
| Cropped width and height, defaults to orig- inal width and height. |
| x,y |
| Position of the cropped picture, defaults to center. |
| cropdetect[=0-255] |
| Calculates necessary cropping parameters and prints the recommended parameters to stdout. The thresh- old can be optionally specified from nothing (0) to everything (255). (default: 24) |
| rectangle[=w:h:x:y] |
| The plugin responds to the input.conf directive 'change_rectangle' that takes two parameters. |
| w,h |
| width and height (default: -1, maximum pos- sible width where boundaries are still vis- ible. |
| x,y |
| top left corner position (default: -1, up- permost leftmost) |
| expand[=w:h:x:y:o] |
| Expands (not scales) movie resolution to the given value and places the unscaled original at coordi- nates x, y. Can be used for placing subtitles/OSD in the resulting black bands. |
| w,h |
| expanded width,height (default: original width,height). Negative values for w and h are treated as offsets to the original size. |
| EXAMPLE |
| ex- pand=0:-50:0:0 |
| adds a 50 pixel border to the bottom of the picture |
| x,y |
| position of original image on the expanded image (default: center) |
| o |
| OSD/subtitle rendering |
|
0: disable (default) 1: enable |
| flip |
| Flips the image upside down. See also option -flip. |
| mirror |
| Mirrors the image on the Y axis. |
| rotate[=<0-7>] |
| Rotates and flips (optional) the image +/- 90 de- grees. For parameters between 4-7 rotation is only done if the movie's geometry is portrait and not landscape. |
| scale[=w:h[:c[:p]]] |
| Scales the image with the software scaler (slow) and performs a YUV<->RGB colorspace conversion (al- so see -sws option). |
| w,h |
| new width/height after scaling (default: original width,height) Note: If -zoom is used, and underlying filters (including libvo) are incapable of scaling, then it defaults to d_width/d_height! |
|
0: scaled d_width/d_height -1: original width/height -2: Calculate w/h using the other di- mension and the prescaled aspect ratio. -3: Calculate w/h using the other di- mension and the original aspect ratio. |
| c |
| chroma skipping |
|
0: use all available input lines for chroma 1: use only every 2. input line for chroma 2: use only every 4. input line for chroma 3: use only every 8. input line for chroma |

| scaling parameter (depends upon the scaling method used) |
|
-sws 2 (bicubic): sharpness (0 (soft) - 100 (sharp)) -sws 7 (gaussian): sharpness (0 (soft) - 100 (sharp)) -sws 9 (lanczos): filter length (1 - 10) |
| dsize={aspect|w:h} |
| Changes the intended display size/aspect at an ar- bitrary point in the filter chain. Aspect can be given as a fraction (4/3) or floating point number (1.33). Alternatively, you may specify the exact display width and height desired. Note that this filter does NOT do any scaling itself; it just af- fects what later scalers (software or hardware) will do when auto-scaling to correct aspect. |
| yuy2 |
| Forces software YV12/I420 or 422P to YUY2 conver- sion. Useful for video cards/drivers with slow YV12 but fast YUY2 support. |

| Also perform R <-> B swapping. |
| palette |
| RGB/BGR 8 -> 15/16/24/32bpp colorspace conversion using palette. |
| format[=fourcc] |
| Restricts the colorspace for the next filter with- out doing any conversion. Use together with the scale filter for a real conversion. |
| fourcc |
| format name like rgb15, bgr24, yv12, etc (default: yuy2) |
| pp[=filter1[:option1[:option2...]]/[-]filter2...] (see -pphelp too) |
| This option enables usage of MPlayer's internal postprocessing filter, and also gives an interface where you can pass options to the named filter. To get a list of available filters, use -pphelp. |
|
Note that each sub-filter must be separated with a /
sign. Each filter defaults to 'c' (chrominance). The keywords accept a '-' prefix to disable the op- tion. A ':' followed by a letter may be appended to the option to indicate its scope: |
| a |
| Automatically switches the filter off if the CPU is too slow. |
| c |
| Do chrominance filtering, too. |
| y |
| Do not do chrominance filtering (only lumi- nance filtering). |
| EXAMPLES: |
| -vf pp=hb/vb/dr/al |
| horizontal and vertical deblocking, dering- ing and automatic brightness/contrast |
| -vf pp=hb/vb/dr/al/lb |
| horizontal and vertical deblocking, dering- ing, automatic brightness/contrast and lin- ear blend deinterlacer |
| -vf pp=de/-al |
| default filters without brightness/contrast correction |
| -vf pp=de/tn:1:2:3 |

| fps |
| force output fps (float value) (default: 0, autodetect based on height) |
| fame |
| Fast software YV12 to MPEG1 conversion with libfame for use with DVB/DXR3. |
| dvbscale[=aspect] |
| Set up optimal scaling for DVB cards, scaling the X axis in hardware and calculating the Y axis scaling in software to keep aspect. It's only useful to- gether with expand+scale (-vf dvb- scale,scale=-1:0,expand=-1:576:-1:-1:1,lavc). |
| aspect |
| control aspect ratio, calculate as DVB_HEIGHT*ASPECTRATIO (default: 576*4/3=768), set it to 576*(16/9)=1024 for a 16:9 TV. |
| noise[=luma[u][t|a][h][p]:chroma[u][t|a][h][p]] |
| Adds noise. |
| <0-100> |
| luma noise |
| <0-100> |
| chroma noise |
| u |
| uniform noise (gaussian otherwise) |
| t |
| temporal noise (noise pattern changes be- tween frames) |
| a |
| averaged temporal noise (smoother, but a lot slower) |
| h |
| high quality (slightly better looking, slightly slower) |
| p |
| mix random noise with a (semi)regular pat- tern |
| denoise3d[=luma:chroma:time] |
| This filter aims to reduce image noise producing smooth images and making still images really still (This should enhance compressibility.). It can be given from 0 to 3 parameters. If you omit a param- eter, a reasonable value will be inferred. |
| luma |
| spatial luma strength (default = 4) |
| chroma |
| spatial chroma strength (default = 3) |
| time |
| temporal strength (default = 6) |
| hqdn3d[=luma:chroma:time] |
| High precision/quality version of the denoise3d filter. Parameters and usage are the same. |
| eq[=bright:cont] |
| Software equalizer with interactive controls just like the hardware equalizer, for cards/drivers that do not support brightness and contrast controls in hardware. Might also be useful with MEncoder, ei- ther for fixing poorly captured movies, or for slightly reducing contrast to mask artifacts and get by with lower bitrates. Initial values in the range -100 - 100 may be given on the command line. |
| eq2[=gamma:contrast:brightness:satura- tion:rg:gg:bg] |
| Alternative software equalizer that uses lookup ta- bles (very slow), allowing gamma correction in ad- dition to simple brightness, contrast and satura- tion adjustment. Note that it uses the same MMX optimized code as -vf eq if all gamma values are 1.0. The parameters are given as floating point values. Parameters rg, gg, bg are the independent gamma values for the Red, Green and Blue compo- nents. Defaults are 1.0, brightness=0.0. Value ranges are 0.1-10 for gammas, -2-2 for contrast (negative values result in a negative image), -1-1 for brightness and 0-3 for saturation. |
| halfpack[=f] |
| Convert planar YUV 4:2:0 to half-height packed 4:2:2, downsampling luma but keeping all chroma samples. Useful for output to low-resolution dis- play devices when hardware downscaling is poor quality or is not available. Can also be used as a primitive luma-only deinterlacer with very low cpu usage. By default, halfpack averages pairs of lines when downsampling. The optional parameter f can be 0 to only use even lines, or 1 to only use odd lines. Any other value for f gives the default (averaging) behavior. |
| ilpack |
| When interlaced video is stored in YUV 4:2:0 for- mats, chroma interlacing does not line up properly due to vertical downsampling of the chroma chan- nels. This filter packs the planar 4:2:0 data into YUY2 (4:2:2) format with the chroma lines in their proper locations, so that in any given scanline, the luma and chroma data both come from the same field. |
| decimate[=max:hi:lo:frac] |
| Drops frames that don't differ greatly from the previous frame in order to reduce framerate. The argument max (if positive) sets the maximum number of consecutive frames which can be dropped, or (if negative) the minimum interval between dropped frames. A frame is a candidate for dropping if no 8x8 region differs by more than a threshold of hi, and if not more than frac portion (1 meaning the whole image) differs by more than a threshold of lo. Values of hi and lo are for 8x8 pixel blocks and represent actual pixel value differences, so a threshold of 64 corresponds to 1 unit of difference for each pixel, or the same spread out differently over the block. The main use of this filter is for very-low-bitrate encoding (e.g. streaming over di- alup modem), but it could in theory be used for fixing movies that were inverse-telecined incor- rectly. |
| dint[=sense:level] |
| Detects and drops first of interlaced frames in video stream. Values can be from 0.0 to 1.0 - first (default 0.1) is relative difference between neighbor pixels, second (default 0.15) is what part of image have to be detected as interlaced to drop the frame. |
| lavcdeint |
| Use libavcodec's deinterlace filter. |
| unsharp=l|cWxH:amount[:l|cWxH:amount] |
| Unsharp mask / gaussian blur. |
| l |
| Apply effect on luma component. |
| c |
| Apply effect on chroma components. |
| WxH |
| width and height of the matrix, odd sized in both directions (min = 3x3, max = 13x11 or 11x13, usually something between 3x3 and 7x7) |
| amount |
| Relative amount of sharpness/blur to add to the image (a sane range should be -1.5 - 1.5). |
|
<0: blur >0: sharpen |
| swapuv |
| Swap U & V plane. |
| il=[d|i][s][:[d|i][s]] |
| (de)interleaves lines. The goal of this filter is to add the ability to process interlaced images pre-field without deinterlacing them. You can fil- ter your interlaced DVD and play it on a TV without breaking the interlacing. While deinterlacing (with the postprocessing filter) removes interlac- ing permanently (by smoothing, averaging, etc) deinterleaving splits the frame into 2 fields (so called half pictures), so you can process (filter) them independently and then re-interleave them. |
| d |
| deinterleave |
| i |
| interleave |
| s |
| swap fields (exchange even & odd lines) |
| field[=n] |
| Extracts a single field from an interlaced image using stride arithmetic to avoid wasting CPU time. The optional argument n specifies whether to ex- tract the even or the odd field (depending on whether n is even or odd). |
| detc[=var1=value2:var2=value2:...] |
| Attempts to reverse the "telecine" process to re- cover a clean, non-interlaced stream at film fram- erate. This filter is still experimental but seems to be usable. Please be aware that there is abso- lutely no use in this filter unless you see inter- lacing when playing the movie! The following argu- ments (see syntax above) may be used to control its behavior: |
| dr |
| Set the frame dropping mode. 0 (default) means don't drop frames to maintain fixed output framerate. 1 means always drop a frame when there have been no drops or telecine merges in the past 5 frames. 2 means always maintain exact 5:4 input to output frame ratio. (Note: use mode 1 with MEncoder!) |
| am |
| Analysis mode. Available values are 0 (fixed pattern with initial frame number specified by fr=#) and 1 (agressive search for telecine pattern). Default is 1. |
| fr |
| Set initial frame number in sequence. 0-2 are the three clean progressive frames; 3 and 4 are the two interlaced frames. The default, -1, means "not in telecine se- quence". The number specified here is the type for the imaginary previous frame be- fore the movie starts. |
| tr0, tr1, tr2, tr3 |
| Threshold values to be used in certain modes. |
| ivtc[=1] |
| Experimental "stateless" inverse telecine filter. Rather than trying to lock on to a pattern like the detc filter does, ivtc makes its decisions indepen- dently for each frame. This will give much better results for material that has undergone heavy edit- ing after telecine was applied, but as a result it is not as forgiving of noisy input, for example TV capture. The optional parameter (ivtc=1) corre- sponds to the dr=1 option for the detc filter, and should be used with MEncoder but not with MPlayer. As with detc, you must specify the correct output framerate (-ofps 23.976) when using MEncoder. |
| pullup |
| Third-generation pulldown reversal (inverse telecine) filter, capable of handling mixed hard-telecine, 24 fps progressive, and 30 fps pro- gressive content. The pullup filter is designed to be much more robust than detc or ivtc, but it is still under development. No configuration options are available yet. As the underlying pulldown re- versal engine is designed to take advantage of the new features in MPlayer G2, the current implementa- tion in G1 is meant to serve mainly as a testbed. Note: presently pullup lacks any way to cap the output framerate, so during 30 fps progressive se- quences or stills, it will output more than 24 fps, meaning you'll have trouble if you use it with men- coder -ofps 23.976. |
| softpulldown |
| This filter works only correct with MEncoder and acts on the MPEG2 flags used for soft 3:2 pulldown (soft telecine). If you want to use the ivtc or detc filter on movies that are partly soft telecined, inserting this filter before them should make them more reliable. Currently only libmpeg2 exports the needed flags. If used on material that does not set them or if using ffmpeg12, the filter does nothing. |
| telecine[=start] |
| Apply 3:2 "telecine" process to increase framerate by 20%. This most likely will not work correctly with MPlayer, but it can be used with 'mencoder -fps 29.97 -ofps 29.97 -vf telecine'. Both fps op- tions are essential! (A/V sync will break if they are wrong.) The optional start parameter tells the filter where in the telecine pattern to start (0-3). |
| tinterlace[=mode] |
| Temporal field interlacing -- merge pairs of frames into an interlaced frame, halving the framerate. Even frames are moved into the upper field, odd frames to the lower field. This can be used to ful- ly reverse the effect of the tfields filter (in mode 0). Available modes are: |
| 0 |
| odd frames into upper field, even to lower, generating a full-height frame at half the framerate |
| 1 |
| only output odd frames, even frames are dropped, height unchanged |
| 2 |
| only output even frames, odd frames are dropped, height unchanged |
| 3 |
| expand each frame to full height, but pad alternate lines with black, framerate un- changed |
| tfields[=mode] |
| Temporal field separation -- split fields into frames, doubling the output framerate. Like the telecine filter, "tfields" will only work properly with MEncoder, and only if both -fps and -ofps are set to the desired (double) framerate! Available modes are: |
| 0 |
| leave fields unchanged (this will jump/flicker) |
| 1 |
| interpolate missing lines (the algorithm used might not be so good) |
| 2 |
| translate fields by 1/4 pixel with linear interp (no jump) |
| 4 |
| translate fields by 1/4 pixel with 4tap filter (higher quality) |

| width, height |
| size of image/area |
| xpos, ypos |
| start blitting at X/Y position |
| alpha |
| set alpha difference. If you set this to -255 you can then send a sequence of AL- PHA-commands to set the area to -225, -200, -175 etc for a nice fade-in-effect! ;) |
|
0: same as original 255: makes everything opaque -255: makes everything transparent |
| clear |
| clear the framebuffer before blitting. |
|
0: The image will just be blitted on top of the old one, so
you don't need to send 1,8MB of RGBA32 data everytime a
small part of the screen is updated. 1: clear |
| framestep=I|[i]step |
| Renders only every nth frame or every Intra (key) frame. |
| If you call the filter with I (uppercase) as the parameter, then ONLY keyframes are rendered. For DVDs it generally means one in every 15/12 frames (IBBPBBPBBPBBPBB), for AVI it means every scene change or every keyint value (see -lavcopts keyint= value if you use MEncoder to encode the video). |
| When a key frame is found, an "I!" string followed by a newline character is printed, leaving the cur- rent line of mplayer/mencoder output on the screen, because it contains the time (in seconds) and frame number of the keyframe (You can use this informa- tion to split the AVI.). |
| If you call the filter with a numeric parameter 'step' then only one in every 'step' frames is ren- dered. |
| If you put an 'i' (lowercase) before the number then an I! is printed (like the I parameter). |
| If you give only the i then nothing is done to the frames, only I! is printed. |
| tile=xtile:ytile:output:start:delta |
| Tile a series of images into a single, bigger im- age. |
| The parameters are: |
| xtile |
| number of tiles on the x axis (default: 5) |
| ytile |
| number of tiles on the y axis (default: 5) |
| output |
| Render the tile when 'output' number of frames are reached, where 'output' should be a number less than xtile * ytile. Miss- ing tiles are left blank. You could, for example, write an 8 * 7 tile every 50 frames to have one image every 2 seconds @ 25 fps. |
| start |
| pixel at the start (x/y) (default: 2) |
| delta |
| pixel between 2 tiles, (x/y) (default: 4) |
| If you omit a parameter or use a value less than 0, then the default value is used. You can also stop when you're OK (... -vf tile=10:5 ...) |
| It is probably a good idea to put the scale filter before the tile :-) |
| delogo[=x:y:w:h:t] |
| Suppresses a TV station logo by a simple interpola- tion of the surrounding pixels. Just set a rectan- gle covering the logo and watch it disappear (and sometimes something even uglier appear - your mileage may vary). |
| x,y |
| Position of the top left corner of the lo- go. |
| w,h |
| Width and height of the cleared rectangle. |
| t |
| Thickness of the fuzzy edge of the rectan- gle (added to w and h). When set to -1, a green rectangle is drawn on the screen to simplify finding the right x,y,w,h parame- ters. |
| -audio-delay <0.0-...> |
| Sets the audio delay field in the header. Default is 0.0, negative values do not work. This does not delay the audio while encoding, but the player will see the default audio delay, sparing you the use of the -delay option. |
| -audio-density <1-50> |
| Number of audio chunks per second (default is 2 for 0.5s long audio chunks). |
|
NOTE: CBR only, VBR ignores this as it puts each packet in a new chunk. |
| -audio-preload <0.0-2.0> |
| Sets up audio buffering time interval (default: 0.5s). |
| -endpos <[[hh:]mm:]ss[.ms]|size[b|kb|mb]> (see -ss and -sb option too) |
| Stop encoding at given time or byte position. Can be specified in many ways: |
|
NOTE: Byte position won't be accurate, as it can only stop at a frame boundary. |
| EXAMPLE: |
| -endpos 56 |
| encode only 56 seconds |
| -endpos 01:10:00 |
| encode only 1 hour 10 minutes |
| -endpos 100mb |
| encode only 100 MBytes |
| -ffourcc <fourcc> |
| Can be used to override the video fourcc of the output file. |
| EXAMPLE: |
| -ffourcc div3 |
| will have the output file contain 'div3' as video fourcc. |
| -include <configuration file> |
| Specify configuration file to be parsed after the default ones. |
| -info <option1:option2:...> (AVI only) |
|
Specify the info header of the resulting AVI file. Available options are: |

| -noskip |
| Do not skip frames. |
| -o <filename> |
| Outputs to the given filename, instead of the de- fault 'test.avi'. |
| -oac <codec name> |

| -oac pcm |
| encode to uncompressed PCM |
| -oac mp3lame |
| encode to MP3 (using Lame) |

| -of avi |
| encode to avi (default) |
| -of mpeg |
| encode to mpeg |
| -ofps <fps> |
| The output file will have different frame/sec than the source. You MUST set it for variable fps (asf, some mov) and progressive (29.97fps telecined mpeg) files. |
| -ovc <codec name> |
| Encode with the given video codec. Use -ovc help to get a list of available codecs. (no default set) |

| -skiplimit <value> |
| Maximal skipable frames after non-skipped one (-noskiplimit for unlimited number). |
| -v, -verbose |
| Increment verbose level (more -v means more ver- bosity). |
| 0 |

| some basic debug infos, avi header, func- tion values (init debug) |
| 2 |
| print avi indexes, chunk inputs, more debug infos (player debug) |
| 3 |
| prints everything related to input parsers (parser debug) |
| -vobsubout <basename> |
| Specify the basename for the output .idx and .sub files. This turns off subtitle rendering in the encoded movie and diverts it to Vobsub subtitle files. |
| -vobsuboutid <langid> |
| Specify the language two letter code for the subti- tles. This overrides what is read from the DVD or the .ifo file. |
| -vobsuboutindex <index> |
| Specify the index of the subtitles in the output files. (default: 0) |
| You can specify codec specific encoding parameters using the following syntax: |

| vqmin=<1-31> |
| minimum quantizer (pass 1/2) |
| 1 |
| Not recommended (much larger file, little quality difference and weird side effects: msmpeg4, h263 will be very low quality, ratecontrol will be confused resulting in lower quality and some decoders will not be able to decode it). |
| 2 |
| Recommended for normal mpeg4/mpeg1video en- coding (default). |
| 3 |
| Recommended for h263(p)/msmpeg4. The rea- son for preferring 3 over 2 is that 2 could lead to overflows (this will be fixed for h263(p) by changing the quantizer per MB in the future, msmpeg4 cannot be fixed as it does not support that). |
| vqscale=<1-31> |
| Constant quantizer / constant quality encoding (se- lects fixed quantizer mode). A lower value means better quality but larger files (default: 0 (dis- abled)). 1 is not recommended (see -vqmin for de- tails). |
| vqmax=<1-31> |
| maximum quantizer (pass 1/2) 10-31 should be a sane range (default: 31) |
| mbqmin=<1-31> |
| minimum macroblock quantizer (pass 1/2) (default: 2) |

| 0 |
| no B frames (default) |
| 0-2 |
| sane range for MPEG4 |
| vme=<0-5> |
| motion estimation method. Note: 0-3 currently ig- nores the amount of Bits spent, so quality may be low. Available methods are: |

| 3 |
| phods (low quality) |
| 4 |
| EPZS (default) |
| 5 |

| mbd=<0-2> |
| Macroblock decision algorithm (high quality mode), encode each macro block in all modes and choose the best. This is slow but results in better quality and file size. |
| 0 |
| use mbcmp (default) |
| 1 |
| select the MB mode which needs the fewest bits (=vhq) |
| 2 |
| select the MB mode which has the best rate distortion |
| v4mv |
| Allow 4 motion vectors per macroblock (slightly better quality). (default: disabled) |
| keyint=<0-300> |
| maximum interval between keyframes in frames. Keyframes are needed for seeking as seeking is only possible to a keyframe but keyframes need more space than other frames so larger numbers here mean slightly smaller files, but less precise seeking, 0 means no key frames. Values >300 are not recom- mended as the quality might be bad depending upon decoder, encoder and luck. For a strict MPEG1/2/4 compliance this would have to be <=132. (default: 250 or one key frame every ten seconds in a 25fps movie) |
| vb_strategy=<0-1> |
| strategy to choose between I/P/B frames (pass 2): |
| 0 |
| always use the maximum number of B frames (default) |
| 1 |
| avoid B frames in high motion scenes (will cause bitrate misprediction) |
| vpass=<1-2> |
| Activates internal two pass mode, only specify if you wish to use two pass encoding (default: dis- abled). |
| 1 |
| first pass |
| 2 |
| second pass |
| huffyuv: |
| pass |
| saves statistics |
| pass |
| encodes with an optimal Huffman table based upon pass 1 statistics. |
| aspect=<x/y> |
| Store movie aspect internally, just like MPEG files. Much nicer solution than rescaling, because quality isn't decreased. Only MPlayer will play these files correctly, other players will display them with wrong aspect. The aspect parameter can be given as a ratio or a floating point number. |
| EXAMPLE: |
| aspect=16/9 or aspect=1.78 |
| autoaspect |
| Same as the aspect option, but automatically com- putes aspect, taking into account all the adjust- ments (crop/expand/scale/etc.) made in the filter chain. |
| vbitrate=<value> |
| specify bitrate (pass 1/2). Warning: 1kBit = 1000 Bits. |

| vratetol=<value> |
| approximated filesize tolerance in kBit. 1000-100000 is a sane range. (warning: 1kBit = 1000 Bits) (default: 8000) |
| vrc_maxrate=<value> |
| maximum bitrate in kbit/sec (pass 1/2) |
| vrc_minrate=<value> |
| minimum bitrate in kbit/sec (pass 1/2) |
| vrc_buf_size=<value> |
| buffer size in kbit (pass 1/2). Note: vratetol should not be too large during the second pass or there might be problems if vrc_(min|max)rate is used. |
| vb_qfactor=<-31.0-31.0> |
| quantizer factor between B and non B frames (pass 1/2) (default: 1.25) |
| vi_qfactor=<-31.0-31.0> |
| (pass 1/2) (default: 0.8) |
| vb_qoffset=<-31.0-31.0> |
| quantizer offset between B and non B frames (pass 1/2) (default: 1.25) |
| vi_qoffset=<-31.0-31.0> |
|
(pass 1/2) (default: 0.0) if v{b|i}_qfactor > 0 I/B-Frame quantizer = P-Frame quantizer * v{b|i}_qfactor + v{b|i}_qoffset else do normal ratecontrol (dont lock to next P frame quantizer) and set q= -q * v{b|i}_qfactor + v{b|i}_qoffset |
| Tip: To do constant quantizer encoding with differ- ent quantizers for I/P and B frames you can use: vqmin= <ip_quant>:vqmax= <ip_quant>:vb_qfactor= <b_quant/ip_quant> |
| vqblur=<0.0-1.0> |

| 2. DC coefficients |
| (low res picture) |
| 3. AC coefficients |
| (details) |
| MV & DC are most important, loosing them looks far worse than loosing the AC and the 1. & 2. parti- tion. (MV&DC) are far smaller than the 3. parti- tion (AC) meaning that errors will hit the AC par- tition much more often than the MV&DC partitions. Thus, the picture will look better with partition- ing than without, as without partitioning an error will trash AC/DC/MV equally. |

| trell |
| Trellis searched quantization. This will find the optimal encoding for each 8x8 block. Trellis searched quantization is quite simple a optimal quantization in the PSNR vs bitrate sense (assuming that there would be no rounding errors introduced by the IDCT, which is obviously not the case) it simply finds a block for the minimum of error and lambda*bits. |
| lambda |
| qp dependant constant |
| bits |
| amount of bits needed to encode the block |
| error |
| sum of squared errors of the quantization |
| cbp |
| Rate distorted optimal coded block pattern will se- lect the coded block pattern which minimizes dis- tortion + lambda*rate this can only be used togeth- er with trellis quantization |
| mv0 |
| try to encode each MB with MV=<0,0> and choose the better one this has no effect if mbd=0 |
| last_pred=<0-99> |

| 0 |
| (default) |
| a |

| subq=<1-8> |
| subpel refinement quality (for qpel) (default: 8). Note: This has a significant effect on the speed. |
| psnr |
| print the psnr (peak signal to noise ratio) for the whole video after encoding and store the per frame psnr in a file with a name like 'psnr_hhmmss.log'. Returned values are in dB (decibel), the higher the better. |
| mpeg_quant |
| use MPEG quantizers instead of H.263. (default: disabled) (i.e. use H.263 quantizers) |
| aic |
| ac prediction (=advanced intra prediction for H.263+) Note: vqmin should be 8 or larger for AIC H263+ |
| umv |

| ibias=<-256-256> |
|
intra quantizer bias (256 == 1.0) mpeg style quantizer default: 96 h263 style quantizer default: 0 Note: the h263 MMX quantizer cannot handle positive biases (set vfdct=1or2) the mpeg MMX quantizer cannot handle negative biases (set vfdct=1or2) |
| pbias=<-256-256> |
|
inter quantizer bias (256 == 1.0) mpeg style quantizer default: 0 h263 style quantizer default: -64 Note: the h263 MMX quantizer cannot handle positive biases (set vfdct=1or2) the mpeg MMX quantizer cannot handle negative biases (set vfdct=1or2) Tip: a more positive bias (-32 - -16 instead of -64) seems to improve the PSNR |
| inter_matrix=<comma separated matrix> |
| Use custom inter matrix. It needs a comma separated string of 64 integers. |
| intra_matrix=<comma separated matrix> |
| Use custom intra matrix. It needs a comma separated string of 64 integers. |
| nuv (-nuvopts) |
|
Nuppel video is based on rtjpeg and lzo. By default frames
are first encoded with rtjpeg and then compressed with lzo.
But both passes can be enabled or not. So you can in fact
output raw i420, lzo compressed i420, rtjpeg, or the default
lzo compressed rtjpeg. Note: The nuvrec documentation contains some advice and examples about the settings to use for the most common TV encodings. |

| packed |
|
create a bitstream that can be decoded delay-free
(default=off) WARNING: this will generate an illegal bitstream, and WILL NOT be decodeable by ISO-MPEG4 decoders except divx/libavcodec/xvid WARNING: this will also store a fake divx version in the file so the bug autodetection of some de- coders might be confused |
