[Buildroot] [PATCH v8 2/7] package/opencv: add gstreamer-1.x support

[Yann E. MORIN <yann.morin.1998@free.fr>]

Samuel, All,

On 2015-07-05 11:40 +0200, Samuel Martin spake thusly:
> Starting with the 2.4.10 release, OpenCV supports both Gstreamer-0.10
> and Gstreamer-1, but only one can be enabled at the same time (OpenCV
> chooses Gstreamer-1 over Gstreamer-0.10 when both are available).
