Thanks, Daniil for having ported OpenCV. This is for sure one of the most useful packages for the device.
Just one question, though: Does anyone have an idea why the following pipeline (based on http://vimeo.com/6866036) doesn't work:
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
It gives me 'WARNING: erroneus pipeline: no element "faceblur"', even though I did install libcv4 and most other OpenCV packages.
