I think you find initially its not bgr but rgb with 1 byte missing at
the start....(i.e. 1 byte if red missing from the first pixel).

hello, i have a bt878 based hauppauge card, and im running linux 2.6.0-test1.
im trying to write a tv program, but when i get data off the card using mmap,
the data doesnt seem to be aligned properly. it seems to be in the order:
GRB, instead of BGR (which is the order i get if i call read() ). i can fix
this temporarily by accessing frame + 2 or frame -1 when i read the data
(frame is the address that mmap returns), but this is obviously not what i
want to do. has anybody experienced this, and can anybody tell me what im
doing wrong? for mmap, im using all the values in the video_mbuf struct given
to me with the VIDIOCGMBUF ioctl.
thanks in advance
