I believe that by now the above answers are outdated (or at least unclear) so here's my little go at it. How to use the ffmpeg options -vcodec and -formats? When I do ffmpeg -formats, I see many acronyms for the codecs supported, I see many acronyms before the codec name/type such as - D V D S E A, what do they stand for? How can I convert the video to a H264 encoded video (raw H264 video format) When I checked the help, ffmpeg -formats, I see below information related to H264 file format and codec: File format :ĭ V D h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10

Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16Īnd then it prints out help on the formats which we get when we do ffmpeg -formats

It still does not work, and gives - Seems stream 0 codec frame rate differs from container frame rate: 59.94 (5994/100) -> 29.97 (30000/1001) Then when i try this option: ffmpeg -i input. mp4 output.h264īut I get an error saying - Unsupported codec for output stream #0.0 I have a *.mp4 video file(MPEG4 video codec) and I am trying to convert this to a H264 video codec format(raw h.264 format) using ffmpeg on Linux(Version - FFmpeg version SVN-r0.5.1-4:0.5.1-1ubuntu1, Copyright (c) 2000-2009 Fabrice Bellard,) using command line as shown below, ffmpeg -i input.
