Comment (by pulkomandy):
The main problem is that gcc2 isn't very good at optimizing the code and
the result is simply too slow to decode the video in realtime. However,
there is an additional problem, which is that we don't handle that
situation well.
At some point, we start to "drop" frames. However, the codec still decodes
them and wastes time doing so. And as a result, it never manages to catch
up with the video replay, as it is always decoding old frames that have
been dropped already.
I don't know why or how this worked before, but it looks out of control of
the ffmpeg decoder and more of a MediaPlayer/Media Kit issue.
