Hi y'all, I started a thread on this topic last October (thread is now closed). I'm back to the topic again. I'm starting to think there is no library that can play Vorbis & Theora . I wanted to create an animated movie clip for my game and the sound would be encoded in Vorbis, movie frames in Theora, all packed into an Ogg file. The library (I call it a Multimedia library) would have the feature of loading an Ogg file and playing sound only (if the Ogg file has sound only), movie only (if the Ogg file has movie frames only) or both. It would also be responsible for managing multimedia playback (I guess this is a good candidate for multi threading). I made good progress last time and I'm resuming now. Before I spend many hours doing this I wanted to make sure that there is no library I can license that can do this for me. Thanks.
