Re: http://v4l2spec.bytesex.org/spec/x6386.htm
Is there a v4l2_field if the capture hardware does the "de-interlacing"
to compensate for motion artifacts for full size NTSC/PAL video?
Our hardware has 2 modes for full size. One where it outputs the top
and bottom fields interlaced without modification(default 2255 setting).
The other where it compensates for motion by removing "comb" or
"feathering" artifacts in the hardware. This second mode still
transmits both fields at the same time interlaced in one buffer.

Sorry, please ignore this question re spec. 0.24. I found the
V4L2_MODE_HIGHQUALITY definition. It's not ideal, however, because
there may be different algorithms implemented (or desired) to remove the
artifacts.
