The complete list of formats and codecs supported by this version is listed at the bottom of this section. libdc1394-22 libgsm1 libschroedinger-1.0-0 libtheora0 libspeex1 libvorbis0a libvorbisenc2 In addition the following libraries will be installed (if they aren't already) to support some of the functionality/codecs. Gets you the ffmpeg command line application (version 0.5.1) and the following libraries: libavcodec52 libavdevice52 libavfilter0 libavformat52 libavutil49 libpostproc51 libswscale0

On Lucid (10.04.2) as of Aprunning sudo apt-get install ffmpeg If you want help or more info on using ffmpeg from the command line see the official documentation site. That's the basics to using FFmpeg, not too complicated.

ffmpeg -i InputVideo.mpg -pass 1 -vcodec mpeg4 -b 3000k -bt 3000k -an -f rawvideo -y /dev/nullįfmpeg -i InputVideo.mpg -pass 2 -vcodec mpeg4 -b 3000k -bt 3000k -acodec flac OutputVideo.mkv The '-y' /dev/null specifies that the output will go into the special null file, which means that it just disappears instead of having to send data to the hard disk. '-f' rawvideo keeps it from trying to pack it into a special format, just to throw away. On Ubuntu, you can do a couple additional things on the first pass to speed it up: '-an' specifies that there is no audio codec to be run. The important part is to call it twice, once with the '-pass 1' paramater and once it finishes run it a second time with the '-pass 2' paramater. Two Pass Encoding It is possible to use ffmpeg for two-pass encoding. The result could look like: ffmpeg -i InputVideo.mpg -vcodec mpeg4 -b 3000k -s hd480 -acodec flac OutputVideo.mkv

ffmpeg OutputVideo.mkvįfmpeg OutputVideo.mp4įfmpeg -f dvd OutputVideo.mpgįfmpeg -f matroska OutputVideo.vidįfmpeg -f mp4 OutputVideo.vidįfmpeg -f avi OutputVideo.vid avi, etc) will allow the program to determine what format the file will be written as, however if it is ambiguious or you want to use format that isn't tied to that file extension, you can use '-f' and the format name. Usually the extension of the filename (.mkv.

The output is where you specify the filename that the converted video will go into. The audio options are where you specify the audio codec ('-acodec') and bit-rate ('-ab'). įfmpeg -vcodec libx264 -vpre medium -b 3000k. In addition you can specify a video preset ('-vpre') which is essential for x264 encoding, and you can specify a size ('-s') with either a standard size reference or the format WIDTHxHEIGTH. The video options are where you specify the codec (with the '-vcodec' option) and bit-rate (with the '-b' option). įfmpeg -i InputVideoTrack.mpg -i InputAudioTrack.wav. You could have more than one of these input files (each one gets its own '-i') if for example you have a video with an audio track in a seperate file. The input part is composed of a '-i' and the name of the video you have that you want to convert to something else. To convert a video, simply run the command 'ffmpeg' with four additional parts: ffmpeg List all container formats: ffmpeg -formats List all codecs: ffmpeg -codecs This may change based on what is installed on your computer, so it is best to check these before running a command, to make sure you have the correct support available. The first two things you can do with FFmpeg are to list out the formats and codecs that this copy supports. The libraries from the project are available for developers to use in their own programs to provide video codecs, formats, devices, filters, scaling, and post-processing.ĭue to patent restrictions for some countries, there are several levels of support for various codecs and formats within Ubuntu's FFmpeg/libav packages. The ffmpeg tool is a command line program that can be used to encode from one of many dozen codecs/formats into a similar number of other formats. The FFmpeg tool and associated libraries (as of Natty, Ubuntu has switched from FFmpeg to the libav fork) is the premier video decoding and encoding system on Linux (and in computing in general).
