I strongly suggest you use a stable FFmpeg build (that’s 0.9 at the moment) instead of git master. Ubuntu users: UbuntuForums has a great guide for compiling newest FFMpeg build. Step 1: Get a new build of FFmpeg Most distribution builds are very old, buggy and have numerous issues. So here’s my guide for encoding web videos using recent FFMpeg versions for Flash and HTML5. 출처 : H.264 Web Video Encoding Tutorial With FFmpeg Web is full of articles about encoding videos with FFmpeg, however most of them are obsolete and use old non-working FFmpeg parameters. I'm using the latest release which is "Happiness": wget I tried compiling ffmpeg with the option -enable-encoders=libx264 and it will give no error but it won't enable anything (I can't seem to find where I found that suggestion).Īnyways step-by-step, first you must compile libx264 yourself because repository version is outdated: wget Īnd then get and compile ffmpeg with libx264 enabled. I believe that by now the above answers are outdated (or at least unclear) so here's my little go at it.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.
