Hi Tanguy, thanks for the pointers, the timing code makes much more
sense now. Sound does indeed make it a lot more problematic, seems I'll
have to do some lateral thinking on this one :\
not a fix for your problem, but experiment with mplayer's "scaletempo"
audio filter. Audio speed up/down without changing pitch.

Hi Michael,
It’s been a long time since I’ve touched the ffmpeg plugin, but here
is how it was:
1/ when the video sound is being played, the video time is
synchronized with the audio player (this tries to keep the video
tightly synchronized with the audio track);
2/ when there is no video sound (or no audio player has been
associated with this video), then the video used to be synchronized
with an internal timer.
Quickly looking at the code on SVN, it does not seem to have changed.
Changing case 2 to be optionally synchronized with FrameStamp
shouldn’t be too hard (but will require code changes in the plugin).
Case 1 looks more problematic though.

I've been playing around with the ffmpeg plugin and I've been very
impressed with how capable it is. The only problem I have with it is
that its playback speed is decoupled from the timing of the main scene.
Does anyone know of an easy way to ensure that the time of the
ffmpeg video is consistent with the time of the FrameStamp?
