If I don't make a mistake, Safari currently need MP4 (H.264/AAC) video encoded for the HTML5 <video>
element.
So I tried to convert a video to this format with ffmpeg
. However when I enter the shell command ffmpeg -i video.flv video.mp4
, the returned error is :
Seems stream 0 codec frame rate differs from container frame rate: 2000.00 (2000/1) -> 29.92 (359/12) Input #0, flv, from 'video.flv':

An AAC codec is required but I'm quite newbie with ubuntu and I dont really now how to fix this problem. I'm using Ubuntu 9.10 Karmik Koala (for amd64).
Thank you very much. :)
FFmpeg supports two AAC-LC encoders ( aac and libfdk_aac ) and one HE-AAC (v1/2) encoder ( libfdk_aac ). The license of libfdk_aac is not compatible with GPL, so the GPL does not permit distribution of binaries containing incompatible code when GPL-licensed code is also included.
http://handbrake.fr is a nice high level tool with a lot of useful presets for mp4 for iPod, PS3, ... with both GUI and CLI interfaces for Linux, Windows and Mac OS X.
It comes with its own dependencies as a single statically linked fat binary so you have all the x264 / aac codecs included.
$ HandBrakeCLI -Z Universal -i myinputfile.mov -o myoutputfile.mp4
To list all the available presets:
$ HandBrakeCLI -z
