How to control the uvc output resolution on MAC?

FEBON168 (1080P version) uvc HDMI grabber card have three resolution 1280x720, 1366x768, 1920x1080.

 MAC free AP " Wirecast"  can solve this problem .

This AP can control the output resolution of UVC device.
It is like the windows AMCAP.
But it is more powerful than AMCAP.
Because it can control the output resolution.
