Re: [Motion-user] Gstreamer MotionCells

[Mailing L. S. <li...@sv...>]

Hi Roman,

I did some contributions to motioncells and I'm actively testing it 
during my free time. I used motion too, but several years ago so my 
comments on motion features below could be inaccurate

it still lack some features that motion has, most notably lightswitch, 
if I remeber motion can track the moving object with a red line, 
motioncells will display the cells where the motion is detected filling 
the border with 1px yellow line (configurable). Howewer you can have 
much more zones (cells) than motion (a grid from 8x8 to 32x32)

Yes it is really fast,on my laptop the detection from v4l2 device 5 fps 
take about 3% cpu usage, at the same time I'm seeing the video with 
outlined the cells where motion is detected too (gst-launch -v -m 
v4l2src ! 'video/x-raw-yuv, width=320, height=240,framerate=5/1'  ! 
ffmpegcolorspace ! motioncells ! ffmpegcolorspace ! xvimagesink)

this is the real killer feature, no more compatibility issue ! You can 
do motion detection on rtp/rtsp stream and obviously mjpeg and local 
v4l2src device. With gstreamer is really easy duplicate the video from a 
v4l2src so no more videoloopback.

Please detail better what do you plan to do (a cli only app?) and which 
language do you plan to use,
