Hi,
It seems my first messages did not get through to the list, because I had not
yet confirmed my subscribtion information.
While trying to decompress a frame captured from my Philips PCVC675K
webcam, I noticed that the colors where swapped.
In the routine pwc_yuv420p_to_rgb24_same_size(), there BGR_OUT() instead
of RGB_OUT() macros are used:

}
d += d_offset_to_next_line * 2;
Due to an error in my capture program I was actually trying to decode an yuv
(V4L2_PIX_FMT_YUV420) frame instead of a raw (V4L2_PIX_FMT_PWC2).
