Let’s analyze the available streams in the original video (remember, UNIX starts counting at zero): Luckily, ffmpeg can fix this for you very easily. I need to delay the audio by 0.2 seconds to make the movie playback in sync. You probably have seen the issue yourself too: for instance, I have a file “original.avi” which has an audio track (or “ stream“) which is slightly out of sync with the video… just enough to annoy the hell out of me. The package will come in handy if you want to try what I am going to describe next. Last in series is ffmpeg-0.9 for which I built Slackware packages (if you want to be able to create mp3 or aac sound, get the packages with MP3 and AAC encoding enabled instead. Ever since there was a fall-out and the ffmpeg developer community split in two (forking ffmpeg into “libav”), ffmpeg itself has seen many releases which tend to incorporate the good stuff from the other team as well as their own advancements. The ffmpeg developers and their libav antipodes are engaged in a healthy battle.
