Ok, i just found out about rawtoppm and ppmtojpeg, but the output's
just a gray box. Then i tried ppmtobmp, still, same result.
I also tried rawtogif, but all i could see are blurs.
BTW, getting this from a raw character device.
Here's some other info:
# ls -l /dev/video0
crw-rw-rw- 1 root root 81, 0 Jun 3 11:46 /dev/video0
Also, since it's a raw device, i also tried fopen("/dev/video0",
RDONLY), then read() to the length that i expect, then i write() it to
a file (vid.raw), but it didn't work. vid.raw is just a 0-length file.
I'm running this as root, with the current directory rwx-able, and
with video rw-able.
Please help.
