I have a problem with manually looping xWMA files. DirectX documentation suggests that if xWMA data is submitted as more than one buffer (as in case of streamed files), then the sound can only be
looped manually by resubmiting the series of xWMA buffers. Consider the following code:
XAUDIO2_BUFFER buffer = { 0 };
buffer.pAudioData = someData; // someData contains the whole xWMA file data chunk.
buffer.AudioBytes = someDataSize;
XAUDIO2_BUFFER_WMA bufferWma = { 0 };
bufferWma.pDecodedPacketCumulativeBytes = someWmaData; // whole dpds chunk.
bufferWma.PacketCount = numWmaPackets;
myVoice->SubmitSourceBuffer( &buffer, &bufferWma ); // myVoice is IXAudio2SourceVoice*.
myVoice->SubmitSourceBuffer( &buffer, &bufferWma );
buffer.Flags = XAUDIO2_END_OF_STREAM;
myVoice->SubmitSourceBuffer( &buffer, &bufferWma );
In this example, the whole file is loaded and looped manually. The first buffer is always played OK, but for every other buffer I get the following trace:
e:\dxsdk\nov08\audio\wma\codecv10\wmaudio\decoder\msaudiodec.cpp(2291) : *** TRACE *** code = 0x6!
Same thing occurs when I split the file into several buffers (then the trace usually pops up when the second buffer of every loop iteration is being played back), but in this case there is an additional problem: OnBufferEnd callback is not called for some buffers and I suppose it is related to that trace. Does anybody has an idea why this may happen?
