Directshow filter in Windows Media Player Mobile on WM5.0

Hi,

I have written a directshow filter for WM5.0 to play YUV files.I can play YUV Files with this filter perfectly with an application that calls RenderFile() but when i try to open files in Windows Media Player (i am able to associate files with Windows Media Player) I am not able to see the playing I just a message saying Opening.....

Is there any particular format for video in Windows Media Player Mobile

Thanks,

    Today I debugged my directshow workspace to play YUV files in windows Media player 10 Mobile on WM5.0 and found that CSourceStream:: FillBuffer() is being called only once and after getting first sample to render it is neher rendering that sample nor coming back to CSourceStream:: FillBuffer() .
    I am using MyFilter class derived from CSource Filter and its output pin is derived from CSourceStream. I am using output media type as {MEDIATYPE_Video,MEDIASUBTYPE_RGB565 }, I even tried with MEDIASUBTYPE_RGB24 but i am getting the same result. It is working perfectly with RenderFile() but not playing inside WMP10 Mobile.
    Can you please guide me what could be wrong here
    Thanks and Regards,

    WMP10 Mobile unfortunately does not use DirectShow graphs to play media. It uses what appears to be DMO filters directly and so far I was not able to see any extensibility path, i.e. you are stuck with the formats currently supported

    But if in am try to play only Audio from a MP4 file with my directshow filter it is working correctly. That means WMP 10 Mobile do accept directshow filters. I feel that for video display i am missing something.

    I am giving RGB565 output from my filter to video renderer as input, could this be an issue

    Regards,
