Hello,
I'm developing an encoder/decoder that compresses .WAV files to WMAudio
format with Windows Media Codec DMO.
In 1-pass and 2-pass CBR mode, it works fine, encoding and decoding both.
In 1-pass VBR mode, the encoding seems to work, but I try to decode,
IMediaObject::ProcessInput/ProcessOutput() function just returns E_FAIL.
(0x80004005)
The encoding part is like this:
pEncoder->SetVBRModeEnable();
pEncoder->SetOutputFormat(...);
pEncoder->SetInputFormat(...);
....
while (IsDataRemain) {
pMediaObject->ProcessInput(...);
pMediaObject->ProcessOutput(...);
}
....
And the decoding part:
pDecoder->SetInputFormat(...); // from pEncoder->GetOutputFormat()
pDecoder->SetOutputFormat(...);
....
while (IsDataRemain) {
pMediaObject->ProcessInput(...); // E_FAIL !!!
pMediaObject->ProcessOutput(...); // E_FAIL !!!
}
....
Any check point to decode VBR WMAudio?
Any difference between CBR and VBR?
Thanks in advance.
