I tried the following command :
xdtv -c /dev/video1 -nodecoinit -force_capt_width 352
It appears that the flag force_capt_height has no
effect on the capture size (stay allways at 576) while
the width flag seems to work proprely.
I have the following error message :
ioctl VIDIOCMCAPTURE(0,yuv420p,352x576): Numerical
result out of range
I use "xdtv v2.0.1 running on Linux/i686 (2.6.10)" from
the Debian repository with a webcam (pwc module).
NB : I can see the webcam stream without problem using
camstream. I can also watch the tv (bttv module) with xdtv.
