Bug#922072: Failure of Hauppauge PVR-150 to obtain any image from a camera connected to the composite

2019-08-15 Thread peter 
Also, a Logitech camera is detected but fails to produce an image.

peter@imager:~$ v4l2-ctl --list-devices
Hauppauge WinTV PVR-150 (PCI::01:04.0):
/dev/video0
/dev/video24
/dev/video32
/dev/radio0
/dev/vbi0

UVC Camera (046d:0807) (usb-:00:1d.7-4):
/dev/video1
/dev/video2

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.

After upgrading Debian 9 => 10 ...

peter@dalton:~$ uname -a
Linux dalton 4.19.0-5-686-pae #1 SMP Debian 4.19.37-5+deb10u2 (2019-08-08) i686

Still no evidence of any functionality in the Hauppauge card.
Not even a dimming of the display when the lens opening is covered.

When the setup was first tested over a year back, there was evidence 
of a crude image at least.  Now nothing.

Any suggestions for troubleshooting?  Some reliable way of testing 
for a signal at the composite connector?  Detected by the PVR?

Thanks, ... Peter E.
