...ideobuf_time=th_granule_time(td,videobuf_granulepos);". Also, there
is no documentation that I can find that describes how Vorbis does
timing, so I came up with the following code, where I calculate my own
timing based on the current byte position in the audio stream:
*audioStartTime = audiobuf_time; // return the buffer time from the
last call, which was the start of the buffer
audiobuf_time = ((double) audiobuf_granulepos)/vi.rate;
audiobuf_granulepos += (*numBytes/2)/2; // a granule is a left/right
stereo pair, so the [size in bytes divided by 16 bits (2 bytes)
divided by stereo (2 c...
