Recording with both main camera and front-facing camera?
 

I don't know if this is possible, searched for a bit but didnt find anything. The idea is to use both of the camera's while filming/shooting picture, so eg, you can see yourself on a pip-ish window. A picture explains better than words i guess, so i made a mockup. It should be very awesome if it was possible! (for the ones who dont get the idea, its a guy in a rollercoaster, you can see the coaster track and his face at once)

From what i've seen in nokia documentation its not possible. The front and main camera use the same bus, so its only one at a time. too bad looks like a nice idea :-) and thereby.. the n900 cant even keep up with only the main cam! dont think it could handle the 2 cams at full res..

Shooting photo like that would be possible, I think? How ever the other would be little delayed.

what about stepping down to 800x480 with main camera and under 1/3 of that with front cam? would that be too much for the bus?
(and frame rate too naturally)

even with still images this would be nice to have: a totally new perspective for photography.

the bus cant handle 2 camera's at once so its not possible even at lowest resolution possible... A picture wil be possible but then its like: Take pic with main cam, software switches to front cam and takes a picture with that. So it will not be at the same moment and the phone could take 5-10 seconds to switch cams

Ah that sucks that they use the same bus. But I still think the idea would be awesome even if it's for pictures.

well - depending on other comments, i may try pushing 2 gstreamer pipelines -
One for /dev/video0
and one for /dev/video1 - ya never know - may randomly work - is a great idea, and nice mock up! :D

How long does it takes for the bus to switch camera?

Couldn't you grab one frame from one and one frame from another and obtain a half framerate movie?

Or they don't switch fast enough. I mean keep the cameras initialized and just switch the bus?

Thanks n00b and icebox, some good thinking there.
