Dear all,
I bought a development board online but I now have problem to use an UVC USB web camera attached to it.
On the device, using adb, I can see /dev/video0 and /dev/video1 is established.
/dev/video0 is onboard camera which have only interface chip and so it is virtual.
The listing of /dev is in the following::
:
:
crw-rw---- system camera 81, 0 2013-05-08 01:13 video0
crw-rw---- system camera 81, 3 2013-05-08 02:07 video1
crw-rw---- system graphics 81, 1 2013-05-08 01:13 video16
crw------- root root 81, 2 2013-05-08 01:13 video17
:
:
When I used skype to test it, the screen is black and seems to be not working.
I have used Tango to test it with friend, still my friend can see black screen.
I have written an App to test it, and finally I get zero number of cameras,
int numberOfCameras = Camera.getNumberOfCameras();
Do anyone have any idea/hint why I cannot use the /dev/video1?
BR,
Terry
