I'm trying to capture color images from the Osprey-100 card and a color
camera using the latest bttv driver
this card has 4 inputs - 3composite and 1svhs
>From the svhs input I can only capture b&w images, while from 2
composite ones I can grab color pictures, using the following codelines:
ioctl(fd, VIDIOCGMBUF, &buffer);
map0.width = WIDTH_L;
map0.height = HEIGHT_L;
map0.frame = 0;
map0.format = VIDEO_PALETTE_RGB24;
map = mmap(0, buffer.size, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0);
chan.channel = 0;
ioctl(fd, VIDIOCSCHAN, &chan);
ioctl(fd, VIDIOCMCAPTURE, &map0);
ioctl(fd, VIDIOCSYNC, &map0.frame);
munmap(map, buffer.size);
When
chan.norm = VIDEO_MODE_AUTO;
I don't get color on the composite inputs too.
I used xawtv for testing : only composite inputs 2/3 in color , s-vhs is
b&w.
xawtv doesn't recognize the first composite input - from this one I can
only grab a b&w image with the above code
television is composite input 2
composite1 is c input 3
s-video and composite3 are the same svhs input
