Title: Raspberry Pi Camera
Post by: dsa4055 on February 04, 2014, 02:16:32 PM

Hi Gene Happy New Year  Nice new Forum
 
Any news about Raspberry Onboard Camera? new driver? a chance that i can use 2014 my Raspberry Onboard Cam? :)


I tried the uv4l driver from
http://www.linux-projects.org/modules/sections/index.php?op=viewarticle&artid=14
 
And then I started the camera with
 sudo uv4l --driver raspicam --auto-video_nr --encoding jpeg --width 160 --height 120 --framerate 1
 It did automatically take /dev/video0
 
HomeGenie did show the image, but most of time it was black or not updating at all. I have tried many different options, like --sched-rr and --mem-lock but it did not help. I have manually started HomeGenie, and have some info from it.

HG v4l wrapper has some issues.
I will add this to the to-do list.

To use rpi camera with hg, the V4L driver must be enabled:

Yeah works but the image is very dark compared to raspistill. Is the driver used the UV4L2 driver written by RpiName, or the V4L2 driver written and maintained by the Foundation? Can we use motion ect with it? and create wizard scripts?
