Comment (by jwjwjw):
Please check this video showing both the clips side by side (old version
left, git master right). For reference, the audio is taken from the right
hand video but it is actually the left hand video that is in sync, which
proves that the audio is identical in both clips.
You can see the frames changing on the left hand video a fraction of a
second before the right hand side, meaning the right hand side is slightly
out of sync. I don't know what else I can do to demonstrate the problem.
It's really clear and distracting for me and is definitely not present in
the old version of ffmpeg.
