v4l2-library: libv4l2 and v4l2convert
libv4l2 offers v4l2_ prefixed versions of
open/close/etc. The API is 100% the same as directly opening /dev/videoX
using regular open/close/etc, the big difference is that format conversion
is done if necessary when capturing. That is if you (try to) set a capture
format which is not supported by the cam, but is supported by libv4lconvert,
then the try_fmt / set_fmt will succeed as if the cam supports the format
and on dqbuf / read the data will be converted for you and returned in
the request format.
v4l2convert: open/close/ioctl/mmap/munmap library call wrapper doing format
conversion
for v4l2 applications which want to be able to simply capture bgr24 / yuv420
from v4l2 devices with more exotic frame formats.
