First thanks for your fantastic effort. You have no doubt made many people happy.
I seem to have found something quite odd. I have two developement machines at work both using the same version of XP and MediaPlayer. On one machine the MediaUriElement works flawlessly and on the other i get the sound but what seems to be a transparent
I am using the d3dimage to draw to my own Border Element with an ImageBrush. I have used DirectShowLib's VMR9Allocator2 app on the problem machine and that works fine. I can also see that the dimentions of the image source from the d3dimage, and that is
what it's meant to be.
I have filled the background of the border with a color on startup and when the MediaUriElement starts to play, it becomes transparent. Can still see the border.
At first i thought perhaps something in the setup of the problem machine, but the VMR9Allocator app works fine.
I have also tried to convert the imagebrush from the d3dimage to a rendertargetbitmap from a thread, and fill that to another element and supprise, i do get an image then? So the surface must be getting each frame.
Any suggestions or require more info?
