I'm writing a DMO decoder to play custom compression type in asf file
in Windows Media Player.
But, i'm now in trouble.
I implemented the IMediaObject and IUnknown completely.
And I tried to make the DMO into the windows media dsp plug-in in
WIndows Player SDK.
Despite all of these, WMP does not call the ProcessOutput function in
my DMO Decoder.
Which else interface should I implement?
The Filter graph manager in Graph Editor calls my DMO deocder
properly, and the decoding work is done successfully.
My another DShow decoder filter working same as the DMO is working
fine in Graph Editor.
and It works well in WMP when playing AVI file conaining same
compressor type media.
And the media negotiation in the GetInput, GetOutput, SetInput,
SetOutput, GetInputSizeInfo and GetOutputSizeInfo is almost same as
the DShow filter's ones.
I'm really wondering :
which else interface should i implement?
how should i write those functions( GetInput, GetOutput... as
mentioned above )?
thanx for reading..
Symtom of my DMO is found on

With best regards...
