4 USB Cameras on Android

hjpark

Hi Firefly

I put 4 USB cameras on RK3288 board and run Android 5.1.1 and tried to open the cameras one by one. ( not at the same time).
I successfully open the 3 Cameras(ID:0,1,2) but can't open the fourth camera(ID:3) with Android Camera1 and 2 APIs.
and I checked /dev/video on the shell and found 4 videos(video0, video1, video2, video3).
so, i thnk that  there is no problem on the H/W but it seems to be an issue on the Camera  API.
If you have ever run 4 USB cameras on Android, please help me run 4 USB Cameras..

thanks a lot..

Best Regards,
HJ Park
