Hi all!
I've problem with playing ogg files. I'm triing to use tripple buffer
method:
+-------------+
+-| buffer 1 |-+
| +-------------+ |
| |
| +-------------+-+
| | buffer 2 |
| +-------------+-+
| |
| +-------------+-+
+-| buffer 3 |
+-------------+
First i fill all buffest with ov_read. Then I start to play firts buffer.
When i stops I'll start to play second buffer and fill firts buffer with
ov_read. Buffer setting are:
p_oggB->wfx.wFormatTag = WAVE_FORMAT_PCM;
p_oggB->wfx.nChannels = oggstruct.vi->channels;
p_oggB->wfx.nSamplesPerSec = (unsigned long) oggstruct.vi->rate;
p_oggB->wfx.wBitsPerSample = 16;
p_oggB->wfx.nBlockAlign = (oggstruct.vi->channels *
p_oggB->wfx.wBitsPerSample) / 8;
p_oggB->wfx.nAvgBytesPerSec = (unsigned long)
(p_oggB->wfx.nSamplesPerSec * p_oggB->wfx.nBlockAlign);
p_oggB->wfx.cbSize = 0;
Could someone send me source code, how he is playing ogg file, or give me
some hint? Thanks a lot!

Thanks a lot!You can send all three buffers to waveOut without waiting for the first one to finish. When a buffer is done playing, fill the played buffer with new data and send it to waveOut. Just make sure you don't overwrite buffers you have sent to waveOut which are still playing or queued for playing. This is a Win32 waveOut question, which has nothing to do with Ogg Vorbis specifically. Better ask somewhere else next time.
