Summary of the bug:
Using https://people.videolan.org/~tmatth/rev.opus when stream-copied or

How to reproduce:
{{{
% ./ffplay rev.opus
./ffplay rev.opus

Note that:
{{{
./ffplay -acodec libopus rev.opus
}}}
doesn't glitch but also that this happens with streamcopying via ffmpeg as
well (so not specific to ffplay).
The file plays fine with VLC, totem, and opsudec also decodes it to wav
without any glitches.
