Ogg QT Component not decompressing

Hi,

I'd like my app to have the ability to play Ogg Vorbis. I currently use a slightly modified version of Kurt Revis' QTSoundFilePlayer (found in PlayBufferedSoundFile at <http://www.snoize.com/>), and have installed the ogg QT Component.

GetMediaDuration() correctly reports 8 seconds at 44100 samples/sec from my test Ogg file, but the first time I call the sound converter I get back zero samples. The decompression atom that the ogg file returns also appears to be okay.

My test Ogg file plays fine in iTunes and QuickTime Player.

I compiled the PlayAudioFile sample code, and it works fine on an mp3 file, but reports the following errors on the ogg file:

  Error:AudioFileOpen=0x7479703F,1954115647,typ??

  Error:NewAudioFilePlayID=0x7479703F,1954115647,typ??????E???4???

But then, it doesn't use QuickTime AFAICT, so I guess I shouldn't expect it to know anything about the Ogg component.

Is there anything obvious I'm missing, should I keep digging, or should I just statically link in the Ogg library and be done with it?

Thanks!
-Kevin
