AudioCodecs don't support video -- CoreAudio doesn't provide any API for doing video. Perhaps that was obvious.. But if you wanted to support for example two different audio codecs in Ogg, then you would need to return the proper AudioStreamBasicDescription as the data format with the appropriate 4 char format ID, Then an AudioCodec that supports that format ID will get instantiated by an AudioConverter. For example CAF (CoreAudio Format) files can contain any kind of audio data format for which there is an AudioCodec.

I have been studying how to impement Ogg Support for MacOsX. I have though that Ogg File Format should be inside into an AudioFileComponent, and Vorbis codec in a AudioCodecComponent.
As Ogg supports Video too ( with other VideoCodecs ) I wouldn't want to implement just another FileComponent for Video ( indeed, I haven't seen the Doc for it ).
So, what's the right way for supporting Ogg File Format for both Audio and Video Codecs reusing the most?
Thank you, Francisco Gimeno
