multi overlay bitmaps and recording RRS feed

  • Question

  • Hi,

    For an application, I have to get MJPEG frame from an IP camera and mix it with several stand alone managed bitmaps. Finally I would like to record it.

    I currently develooped my own source filter (I have a problem to add timestamp (frame is frozen) but I will search before asking a question) that I add into my filter graph.
    The overlay is performed with VMR9 but I have two problems :

    - I can't manage two stand alone overlays :
         I manage the overlay in two separated functions and in the second one, the line 
    HBITMAP hbmp = CreateCompatibleBitmap(m_hDC, 160, 128);
     returns a NULL pointer for hbmp.

    - Using VMR9 avoids me to record the final overlayed frame!!! What may be the best filter graph combinaison for my application?

    Thanks a lot in advance.
