What do you think about adding new M2M capability flag for memory-to-memory
video devices ? I prepared an RFC patch for that already:
http://www.mail-archive.com/linux-media@vger.kernel.org/msg48497.html

I think that at least qualifies to your list of V4L2 API ambiguities, even
though we have device_caps now. Using ORed OUTPUT and CAPTURE flags implies 
all existing applications must check now both flags when they're trying to 
discover a video capture or video output device.
