Thank you for your request and sorry for late reply.

I want to confirm. What you request is that UsbCamera class's access modifier is currently 'internal' and change it to 'public'?

Could you tell me the reason. Are you going to make UsbCamera class to dll? Thank you.

To make UsbCamera class public, you have to make DirectShow class (in line 772) public too. Could you try it?

You can get max/min frame interval from Caps.MinFrameInterval and Caps.MaxFrameInterval in VideoFormat member. The value means duration in 100-nanosecond unit. You can translate into frame rates as follows.

frame rate = 10,000,000 / frame duration. (for example, value=333333 means 30 fps.)

You can change frame interval by modifying TimePerFrame value in VideoFormat member from MinFrameInterval to MaxFrameInterval, but as long as I tested, devices all I have returns same value in MinFrameInterval and MaxFrameInterval.
