AVIStreamRead fails mysteriously

Can anyone help ? I've got the same troubles :

But I'm getting an error when I try to load the audio data. The problem is with
AVIStreamRead(audioStream, 0,AVISTREAMREAD_CONVENIENT, NULL, 0, &lSize, NULL);
This is returning 0x800440c7 and lSize is 0.

I don't have your file so I can only guess...

First: In AVIStreamRead you set "lpbuffer = NULL", so AVIStreamRead does not read any data, it returns information about the size of data that would be read, meaning this is not an error value.

Second: I would not rely on your file containing an audiostream with a wav-format, AVIStreamRead does not provide decompression services.

First : this is ok -> used like this, it should determine the needed space for the buffer

Second : I'm not trying to get a decompressed stream but the raw compressed data

thx anyway ...
