Hi,

I solved the issues (thanks, Klen) and now try to include OpenCV support. I installed the packages recommended by Klen and tried a test pipeline using gst-launch (based on http://vimeo.com/6866036):
Code:
gst-launch v4l2camsrc device=/dev/video0 ! video/x-raw-yuv,width=480,height=272 ! videorate ! capsfilter caps="video/x-raw-yuv,width=480,height=272,framerate=(fraction)12/1" ! queue ! ffmpegcolorspace ! faceblur ! ffmpegcolorspace ! xvimagesink
However, this results in
Code:
WARNING: erroneus pipeline: no element "faceblur"
, which is the only OpenCV component. Without it, the test runs fine. Has anybody working CV support? Could anybody post a minimal example or tell me how to make it run? If we want great CV apps for our N900 we should provide beginners with a solid starting point for OpenCV as well.

Thanks in advance.

EDIT:
There are simply no OpenCV-GStreamer plugins available according to Daniil (thanks!), which is the reason why the pipeline doesn't work.

I wrote a short example for using OpenCV myself, see here:
