What went wrong with ffmpeg? ffmpeg -i stream.ts -c:v copy -c:a copy out.mp4 If you find a sample that does not keep audio sync, the ffmpeg developers would want to see it. Bear in mind that you cannot fix audio sync issues without re-encoding the audio, eg: ffmpeg -i stream.ts -c:v copy -c:a libfaac -filter:a asyncts out.mp4 Cheers Tom
