[Vorbis-dev] artifacting with many channels

[Ethan Fenn]

Hi all,

 

I am using oggenc to compress multichannel audio streams (4-10 channels)
and am having some severe artifacting on decode.  What seems to be
happening is that at times when one channel is silent, one or more of
the other channels will be badly mangled.  Simply reordering the
channels seems to fix the problem sometimes, but not predictably.  It
also seems to be independent of quality used (it happens equally with
quality=-1 and quality=10).

 

Does anyone have any idea what could cause this, and what I might be
able to do to fix it?

 

Thanks,

-Ethan
