Webcam Media Player Format

Im currently displaying a webcam in game and the webcam supports multiple resolution 720p 1080p etc. How do i force it to be 720p60fps? Right now its defaulting to Format 0 and i want format 296.

Set Track Format isnt working as expected.

I was looking for same thing for long time and I figured it out today. Just had to add 0.2 delay before set track. Also can change framerates.
