CLSID_CResizerDMO resize video frames

Hi,

I`ve a video frame with the size 1280 x 720 and I want to resize this frame to 55 x 31. Unfortunately using the video resizer dsp (CLSID_CResizerDMO) it is not always working.

When I set the output type (SetOutputType) I get the return error E_INVALIDARG. Resizing the video is not working as expected, the video frame has the size 1280 x 31 instead of 55 x 31.

When I set the frame size to 60 x 34, I can set the output type (SetOutputType) and I can also resize the video frame as expected.

Could you tell me why the first resize test is not working as expected? Are there some problems with odd video width sizes?

best regards
