Updates the video frame.
MFPMediaPlayer_UpdateVideo PROTO MediaPlayer:DWORD
Parameters
MediaPlayer- A pointer to the Media Player (IMFPMediaPlayer) object.
Returns
TRUE if successful or FALSE otherwise.
Notes
Is supposed to allow painting in WM_PAINT or WM_SIZE when video is not rendering, but tests show that this isn’t the case. At a best guess the window that is used to render is sub-classed and doesn’t pass back the chain of events for WM_PAINT once rendering starts. My workaround for this to allow a custom draw of the video window when not playing is to hide the window when stopped and show it when playing, this allows the background of the parent window to show any custom painting, including a fake video screen with a logo.
