MAC skype just eat 1280x720. we can not choice the uvc uvc output resolution.
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.
The experiment as below is FEBON168 UVC HDMI grabber as the sample.
After installing the "Wirecast ", we can choice the icon " show source setting"
If we do not use Wirecast to control, the default uvc output resolution of MAC skype is 1280X720
After we use wirecast to contorl resolution, we can choice the 1920X1080.
Finally, we can see the video resolution is the same as Wirecast.
