ffmpeg conversion skips audio
10 mars 2012, par user504879While converting a video to mp4 format using ffmpeg the audio gets skipped because of which the audio goes out of sync with the Video.

flv reencode to mp4 for iphone/ipod via ffmpeg and x264 (quality issue)
3 octobre 2011, par zeroasteriskThere are a lot of questions on this topic, and I've read most of them and most of the google search results I could come up with.
When I use FFMPEG to convert a FLV to a iphone3 compatble MP4 file, it just doesn't preserver enough of the quality. Yes, I've worked the hell out of
-sameqand-band-btsettings, text just isn't readable.Next I tried to split the video out and process it directly, using these instructions :
https://sites.google.com/site/linuxencoding/x264-encoding-guideThe problem is myplayer (via ffmpeg) was not able to determine the duration of the FLV (even though the metadata was set).
(I assume) Because of that unknown duration, when I create the MP4 file, the resulting x264 file plays through super-fast while the audio plays at the normal rate.
