I have some trouble with setting media format of Windows Media Audio 9 codec.
I’m building graph and after adding an audio source, audio compressor
(Windows Media Audio 9 or Windows Media Audio 10 Professional - WMAudio
Encoder DMO) and connecting source to compressor I’m trying to change media
type of output pin of the compressor – I’m using a GetMediaTypes method of
output pin of the compressor and after that I’m trying to change to one if
the returned formats but I always have a ‘pin cannot use the supplied media
type’ exception (HRESULT: 0x8004022A) – when I’m using WM Speech Encoder DMO
everything is ok, but with WMA 9.2 or WMA 10 I’m getting this error for all
kind off avalible formats.
