Android USB Camera - How is it tested?

[mrbrooks]

I'm running Android P (2.3.4) on iMX8MQ and trying to use an external USB camera. I haven't seen anything that implements the Camera2 external camera config (External USB Cameras  |  Android Open Source Project ) but I do see the USB camera enumerate as a UVC camera (and messages from the FSL HAL). Is there documentation on how the camera frames are being read from the external cameras if not the Android CTS external camera suite? The default camera app doesn't support this (just front/rear cameras)/

[weidong_sun]

you can set it in init.rc like below:

setprop back_camera_name uvc

that is to say , modify front or rear to uvc

then you run campera apk to preview it.

Hope above information can help you!

Have a nice day!

Ah yes, that will do it! Didn't see that UVC is enumerated as the front camera (and your command can switch it to the back one). Thanks for your help!
