Is it possible to use analog video output as input?
Is it possible to use analog video output as input?
The RasPi HDMI and Composite video jacks are output-only.
For video input, I suggest that you go to raspberrypi.org and enter "Video Input" in the Google search box on the front page. There is a CSI digital camera header and RasPi is working on a camera module, which I just learned will have composite video input: see this thread chez RasPi: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=63&t=20159
There may also be USB video capture devices -- the "Video Input" search should tell you what (if anything) works.

Hi John,
I think the camera module won't have any analog input (I looked at that thread recently). There was another thread
where someone offered to made a digital input hardware (HDMI I recall) but I think that went nowhere either.
So, I think no video input is planned to be offered on Rasp-Pi, just image or video from the actual camera board.
USB capture devices may be the easiest solution for now, if drivers can be compiled for it.
The unfortunate downside (or I suppose fortunately in some scenarios) is that USB capture devices compress the data.
