Well, in "Changes" is a note that select support was added, so I changed
bttv driver to set V4L2_FLAG_SELECT.
Result is that mp1e now goes:
/usr/local/bin/mp1e:v4l2.c:365: Failed to map capture buffer #0 (22, Invalid argument)
The failure is because mp1e does mmap with MAP_SHARED - which bttv doesn't
like. Its not obvious what value there is to calling with MAP_SHARED -
surely the buffers aren't written to anyway?
