can you provide a example for me?
thank you very much.
I use gradedit.exe, I can add the overlay mixer to the graph, but i can't set the video size to 640*480 with 24bits. It said: Can't support this format.
i delete the overlay mixer from the graph, then i can set the video size to 640*480 with 24bits.
Did you try the various renderers available? Also it may need some color space conversion filter.
What do you need the overlay mixer for? Why the VMR doesn't suit your need?
If your application does not target Windows 2000 or older you should go with VMR.
