Windows 7 - Custom DMO getting error "The output media format is invalid" in W

Hi All
I am writing a DMO that accepts data from a custom encoded ASF file and
outputs it to the WMP renderer as bitmaps.

Input mediasubtype is a custom one (has its own GUID and fourCC)
Output mediasubtype is RGB32 . (reflected in the CheckOutputTypes and
GetOutputTypes functions).


However when I try to play the custom asf file in WMP I get : "The output
media format is invalid."

it is funny that the output media format should be invalid, because the input
is the custom one...

What causes this and what should I check?

Thanks a bunch
Roey

Your DMO_MEDIA_TYPE or VIDEOINFOHEADER may have been filled
in incorrectly. Post a readable dump of the whole structures
(hex is *not* a readable dump).
