Ahh, I see. These people used different settings (different bitrate)
for Vorbis audio, which indeed results in garbled output. I did not
expect that to work in DirectShow either, but it does, albeit barely
(a lot of Vorbis decoder filters did output garbage or hung). It also
makes remuxing impossible (if you force it, the resulting file will
have garbled segments with any decoder), which is kind of a
deal-breaker for ffmpeg I guess.

I'm not sure what would be a solution here.

Keep in mind that different CodecPrivate does not necessarily mean
corrupted output: in the particular case of Vorbis CodecPrivate tends
to vary even if the same settings are used, but it's still possible to
mix the streams without problems. I'd say for now a warning is enough.
