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? Steve
