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).
