Also, a Logitech camera is detected but fails to produce an image.

peter@imager:~$ v4l2-ctl --list-devices
Hauppauge WinTV PVR-150 (PCI:0000:01:04.0):

UVC Camera (046d:0807) (usb-0000:00:1d.7-4):

peter@imager:~$ qv4l2 -d /dev/video1
OpenGL Error 0x500: InitializeGL.
OpenGL Error 0x501: YUY2 shader.
Could not create shader of type 2.
OpenGL Error: YUY2 shader compilation failed.
OpenGL Error 0x500: YUY2 paint.
OpenGL Error 0x502: YUY2 paint.

"OpenGL Error 0x502: YUY2 paint." is repeated until qv4l2 is 
interrupted. I don't understand the significance of the shader.

Thanks,                                    ... P.
