Hi,
I am using i2c-991123 and bttv-v4l2-000321 to simply capture PAL
images from the composite source input using:
vctrl /dev/video0 -w 384 -h 288 -b 24 -i 1 -p
and
vcrtl /dev/video0
reports
384x288 @ 24 bpp from input 1 (composite(0))
The inputs are: 0 = Television: 1 = Composite (0): 2 = S-Video:
The video standard is PAL
and
cat /dev/video0 |rawtoppm -bgr 384 288 > image.ppm
works just fine !!!
However when I try to it set to 768x576x24 using:
vctrl /dev/video0 -w 768 -h 576 -b 24 -i 1 -p
then
vctrl /dev/video0
reports
384x288 @ 24 bpp from input 1 (composite(0))
The inputs are: 0 = Television: 1 = Composite (0): 2 = S-Video:
The video standard is PAL
It appears that it doesn't accept the image size I set and of course my
corresponding cat command ends up with a garbled image.
Has the error in the attached /var/log/messages go anything to do with this ?
Is there something I'm missing or is v4l2 vctrl and videodev unable to do
768x576x24 on a HauppaugeTV-GO ?
Am I better off with V4L and not V4L2 and borrowing a capture application ?
Any suggestions ?
Best Regards
Neville
