Samuel, all,

On 2015-07-04 21:07 +0200, Samuel Martin spake thusly:
> This change adds 2 patches (backported from upstream) to vlc fixing the
> build against opencv2 APIs.
> This allows to select the minimal set of opencv modules when opencv
> support is enabled.

This reviewd tag stands, still I have a question:

objdetect already selects imgproc. So, does vlc w/ opencv really need
imgproc by itself? If so, the select is OK, otherwise, it is
superfluous.
