> I don't quite understand how sound can affect video timing,
If video has audio, audio determines the playback speed. Fluctuations in
audio data or sample rate is not acceptable, it would sound horrible. If
at 25fps a frame is displayed after 39ms or 41ms is irrelevant, even 30
or 50ms would hardly be noticeable. Therefore it is a natural
requirement that audio sets the speed, and video tries to keep pace.
Only if there is no audio, there has to be a different timing source, so
the existence of sound affects the way the video frames are timed.
