I'm seeing some inconsistency in returned timestamps using vorbisfile. I open a file, read some data (grabbing timestamps with ov_pcm_tell), then seek back with ov_pcm_seek(vf, 0) and read it again. The seek lands back on 0, but on the second read through, there's a gap in the timestamps: they jumps up by 2112 frames. This causes my vorbisfile code to insert silence to maintain sync (as if there was a hole), and one of my test c...

...m doing something stupid. The files are short audio effects for a game (embedded in our own data format). Sample info: Vorbis packets: 1 (4 kb) Samples: 28672 Samplerate: 22 kHz Channels: 2 This is what I''m doing when I want to get a number of bytes from the stream: The problem is that ov_pcm_tell always returns 0. And so does ov_read (its only one packet so EOF) virtual bool GetData(void *&_pData, int &_nBytes) { int NumTimesNoData = 0; while(_nBytes) { long ret;...

How do I seek back to the beginning of a stream using ov_pcm_seek()? ov_pcm_seek(0) doesn't seem to do anything, though ov_pcm_tell() returns 0 right after opening the stream. I'm now using ov_pcm_seek(1) which seems to work, but I'm not sure if that's really right. Are PCM offsets meant to be 0 or 1 based? Is this a bug?

...track. Currently when I seek and play the second track it is ~0.5s late (it starts playing immediately, but is offset by ~0.5s). All files are already stored in their compressed state in memory at the time the seek request is given. Each playback occurs on its own (OpenAL) source. I'm using ov_pcm_tell/ov_pcm_seek to seek the second file to the position of the first, and have implemented all of ov_callbacks to facilitate this. I suspect the problem is related to the time that passes between querying with _tell and the playing of the second source. For the benefit of future google searches, I...

Hello! I just got _very_ scared. I was certain the Ogg libraries could be used in commercial products (I know they are used in Star Trek: Away Team and Operation Flashpoint). I've also been told several times that it's OK, even if they're not GPL, but now I can't find any info on the sites that tells me so. Could you please tell me what the deal is (I've used it in a project
