Video playback on secondary primary surface RRS feed

  • Question

  • Hi,

    I am trying to play the video on Secondary surface that is HDMI using directdraw. I am able to play the video, its like drawing frame by frame on an overlay surface. Its not actually overlay, as only one surface can be created on secondary display as per DDRAW documentation. 

    When I draw like this, frames are not properly getting drawn, its like surface is moving from top to bottom, and the drawn images are displaying like mismatched images of a puzzle. What may be the issue? Frames are misplaced or drawn improperly on the surface but the color quality and speed are perfect. I am using YUV frames to check the playback. 

    Is there any way to play MP4 formats without using DirectShow filters like using DDRAW? As far as I know its quite impossible, unless I convert the format to YUV. 

    My ultimate aim is to display two different videos on two screens.

    Any help?
