Re: Updated GPU firmware

Ah yes, some of the config group names have changed in newer kernel, and so large sections of modules we're disabled. I've added back in various groups and we now have uvcvideo.ko amongst others. Can you try again: sudo rpi-update ffe1ad3ccba34e55672a2d8813ddf0a1c81a4230 Thanks, now I can access th...

Re: Mjpg-Streamer

I tested another Logitech webcam which can go to 1600*1200 in MJPEG-mode, but for some reason streaming works very slow with this webcam with the 960*720 resolution which works fine with my older Logitech webcam. The CPU load was very low and I did not see any error messages, but in the browser the ...

Re: Mjpg-Streamer

I tried out mjpg-streamer. A resolution of 960*720 with 15 frames / s results in a CPU load of 7-8 % when using MJPG-images from the webcam. This is very good, so the next problem is to get motion detection working. Has anyone tried using the mjpg-streamer output as input for motion on a different m...

Re: Motion detection on GPU with the CSI camera module?

I found this discussion on some basic motion detection algorithms, that would suit very well execution on the GPU:

One could also have a look on what the motion program uses and try to port that to the GPU.

Offloading motion detection to the GPU would also be useful for normal USB webcams, if one wants to reach higher resolutions and frame rates.

Motion detection on GPU with the CSI camera module?

One obvious use case for the CSI camera module is to run motion detection on the produced images in a similar way as with the motion program and USB-cameras. What would be the best way of doing the motion detection on the GPU? Has someone worked on this already?
