In order for this to work with r3d files, the debayer code will have
to be added. I have a patch which
i'll send after this stuff gets committed. Also, even with all patches
applied, I'm not sure if it will work
with r3d files created with a newer firmware. IIRC the video stream in
those is encrypted.
