Hi all... I'm completely confused. In one machine, I developed a program that uses the v4l2 API and works fine. On another machine it doesn't. I cannot find what went wrong, and I need the thing urgently (of course). The machine that works is kernel 2.4.20, I applied the patch, and use an SAAxxx chip there. Works A-ok. The new machine has 2.4.22 installed, and I applied the 2.4.22-3 patch from bytesex.org. I enabled all the options (I think), and recompiled. Here I have a Pinnacle PCTV (nothing else - no pro/sat/...) 'dmesg' shows the card is recognized as a type 39, and no errors are reported. xawtv works just excellent. So does ttv, and a few others. v4l-info gives me info, but obtained thru v4l1 (VIDEOCGCAP), so it does not recognize v4l2. v4l-conf says: /dev/video0 [v4l2] ioctl VIDIOC_QUERYCAP: Invalid argument, then /dev/video0 [v4l]: configuration done. I didn't see v4l2-common loaded, so I modprobed it manually, no difference. Same with v4l1-compat. I do not have 'Load "v4l"' in either machine in the XF86Config, so I guess this is not necessary. My program relies on v4l2 - Should I change the program to be able to use v4l? Could it have something to do with not having sound installed in the new machine? I've seen quite a few references to the v4l-conf message, but no real answers. HELP!... I'd really appreciate some hints! John
