How activate OpenCV Video Filter

[cakrudy]

Hi all,

I want to see how the work module video filter opencv_example face detection. So I built VLC 0.9.8.
Based on http://trac.videolan.org/vlc/ticket/728, I have done insert --with-opencv-tree in configure.sh, and have changed "opencv-filter-name" variable of the opencv wrapper with "opencv_example".
There were many errors during compilation proses, and finally I have finished "make package-win32-base".
I run VLC.exe. I tried a video sample and look at Tools > Preferences > Show setting all -> video filter, but there was not exist opencv_example and nothing effect ( face detection ) in video display.
So my question is, how acivate opencv video filter ??.

thanks.

Update:
I tried to look at Tools > Extended Settings > tab video effects > tab Advanced video filter controls -> in video filter input I filled with opencv_wrapper > Close, And I saw some small with rectangle but not worked/detected properly. I think it's try to detected the face.

Sorry, noone compiled openCV for a long time... Does it appear on the vlc list of plugins?

I'm so sorry, there was a mistake. Some small rectangle that exist is not the effect of opencv_wrapper but the effect of motiondetect at Tools > Extended Settings > tab video effects > Image Modification.
I look at /modules/video_filter there wasn't libopencv_wrapper_plugin. Why?

you can try this . go into videofilter and use"make libopencv _wrapper_plugin.la" .
