Thanks for reporting this bug; I'll take a look on it tonight after work. I've been having trouble getting opencv-3.0 to build, but I should be able to work through that. Toralf, I think you have a typo (extra y) in your package.use that's preventing opencv USE flag from being disabled.
I haven't written the proper patch yet, but I have tested the fix and it works. Basically with opencv 3.0 the CV_RGB function has been replaced with cvScalar. Additionally the cvRectangle is now declared in opencv2/imgproc/imgproc_c.h. So the fix is simply to update opencv_example.cpp with that header file and replace CV_RGB with cvScalar. On a side note, the order of parameters for cvScalar is the reverse of CV_RGB however since we're just passing 0 to all three parameters in both cases, it doesn't matter for VLC. I don't see this bug upstream yet, so I'll submit it there as well once I write a patch that detects opencv version and does the right thing. On a side note, I could only get opencv-3.0 to build with USE="-python" and eselect python set to python 2.7. Python 3.3 & 3.4 were throwing TypeError: unorderable types on the gen_java.py. I'll try to fix that later although I'm not much of a python person (it's too strict for my taste).
Actually, upon closer inspection, it looks like CV_RGB isn't deprecated, rather it's just moved to opencv2/imgproc/imgproc_c.h so just adding that header is all that is necessary. Anyways, will work on a proper patch later and also backtest 2.1.5.
Upstream bug: https://trac.videolan.org/vlc/ticket/15094
Created attachment 407364 [details, diff] opencv-3.0.0.patch Patch to add headers for the location of CV_RGB & cvRectangle based on upstream commit (http://git.videolan.org/gitweb.cgi/vlc.git/?a=commit;h=b82416d7000a993b33e903095a590fe32212a85e). Works on both 2.1.5-r1 & 2.2.1 with both OpenCV-2.4.10 & 3.0.0.
29 Jul 2015; Ian Delaney <idella4@gentoo.org> +files/opencv-3.0.0.patch, vlc-2.1.5-r1.ebuild, vlc-2.2.1.ebuild: patch to address missed header file in opencv, patch from upstream instigated by maintainer submitted via bug #554562
