Subject:    [video4linux] Discussions of TV extensions for XFree

Just FYI, there's a lot of discussion on the XFree mailing lists right
now about what to do about the different TV cards including writing a TV
extension for the server.  I don't know if anyone on this list is also
on the XFree mailing list but it might be worth it for someone more
technically competent that myself to give input to their discussion.

  I believe Alan Cox had a go at that,  and I've been toying with the
same idea (but haven't yet tried to get video card docs).

  Which list?  The internal xfree lists for their developers?

All you need is

	XVideoAttach(videosource, window)
	XVideoDetach(videosource, window)

for overlays. There is already a 'window clip rectangles changed' callback
that is only used right now by Xnest but can be used to reload the video
clip rectangles smoothly without mess and refreshing from userspace
