Camera Support Thru Android

@mikey0000 Any progress with USB based UVC webcams?

I'm playing with a Logitech HD Pro Webcam C920, which doesn't work nice on Android TV 7.0. I've tried different version, but I get the same log output.

$ dmesg
[   65.597979] uvcvideo: Found UVC 1.00 device HD Pro Webcam C920 (046d:082d)
[   65.612407] input: HD Pro Webcam C920 as /devices/soc.0/1c1a000.ehci0-controller/usb1/1-1/1-1:1.0/input/input8
[   65.629408] usbcore: registered new interface driver uvcvideo

[   65.676303] init: write_file: Unable to open '/sys/devices/soc.0/cpu_budget_cool.16/roomage': No such file or directory

When Skype accesses the camera, I get the following from logcat:

$ adb logcat HALCameraFactory:* VideoService:* V4L2CameraDevice:* *:S
--------- beginning of system

Any help would be appreciated.

I've added the Tellybean "Test Camera" logcat. Here is snippet:
