When I load the codec as an Audio Codec the call to AudioCodecInitialize appears
to work but if I then get the IsInitialized property that says it is not
initialized - so looks like that is my problem, and ties up with the crash in
vorbis_synthesis_start(). Looks like vorbis_synthesis_init() has not been
called, perhaps.
There's sample code out there that suggests people have got this working, so
is it just that I'm missing a call to initialize it somewhere?
I can post code and crash dumps, but I suspect my problem is more basic than
that.
Meanwhile I'm going to build the XiphQT plugin with trace and see what I can
find out that way.
Versions are Mac OS 10.6.6, XiphQT 0.1.9

looks like the XiphQT plugin, although originally QT, also works with core audio
as a codec/converter. I've tried setting it up as an Audio Codec
(FindNextComponent, OpenAComponent, AudioCodecInitialize) and as a Audio
Converter (AudioConverterNew). In both cases the codec loads fine (so probably
is OK to use as a codec/converter) but as soon as I try to start using it I get
a crash in
vorbis_synthesis_start().</div><div><br></div><div>When
