| May 16, 2015 at 5:33 | comment | added | Coderaemon | @DaveJones so none of the remote desktop clients will work? One solution I found elinux.org/RPi-Cam-Web-Interface works okay. Is there any other solution you know of? | |
| May 15, 2015 at 17:37 | comment | added | Dave Jones | Indeed; the camera's preview is rendered by the GPU onto the video output directly. Neither the X server (nor frankly anything running on the CPU as opposed to the GPU) ever sees the preview, so there's no way to transmit it via VNC. Even if there was, VNC (and its compression) is optimized for largely static desktops - the bandwidth for full video would be awful. So no: if you want a video preview on another machine you need to look at proper streaming solutions - you won't get there through VNC. | |

@jaromrax If you use raspistill -o foo.jpg directly on the pi with a monitor plugged in, it does display the camera stream for a few seconds. I'd guess this is a trick manipulating the GPU though, which is probably why it would not come through w/ VNC.

| May 15, 2015 at 11:03 | comment | added | jaromrax | Do you mean that you cannot see the direct output of the camera? If you just save a picture, you must open it, of course... Earlier I also tried to see camera stream on vnc, but it was always a direct communication with videocard, vnc did not transfer that... | |
