Subject: v4l2: Require mplanar support for now in configure
X-Git-Tag: 1.19.3~509^2~4805
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3d9f175d5e106c926a9a07b9e01a05fd43b420d5;p=platform%2Fupstream%2Fgstreamer.git

v4l2: Require mplanar support for now in configure

The code fails to compile without currently, see
https://bugzilla.gnome.org/show_bug.cgi?id=723446

It's better to disable it instead of failing compilation
until this is fixed properly.
