Way cool man!  Tried it immediately, it works but has some problems:

- Strange varying latency.  Bottom fields seem to take 60ms to
capture, this is what gets measured on my system:

  curbuf.field 2; delay = 20ms
  curbuf.field 3; delay = 60ms
  curbuf.field 2; delay = 20ms
  curbuf.field 3; delay = 60ms
  curbuf.field 2; delay = 20ms
  curbuf.field 3; delay = 60ms
  ...

- VIDIOC_DQBUF fails when using 4 buffers (which VIDIOC_REQBUFS
accepts!).  Two and three buffers work fine (but with the above wierd
latency problem).

Looks like it's almost there :-).
