kumquat-buildroot/package/vlc/0008-ffmpeg-3.0.patch
Bernd Kuhls c9c611f998 package/vlc: add support for ffmpeg 3.0 
Instead of bumping vlc to git master (no vlc 3.x release yet) we use a
patch from deb-multimedia.org which provides the necessary changes for
ffmpeg 3.x support to vlc 2.2, compile-tested using this defconfig:

    BR2_TOOLCHAIN_BUILDROOT_WCHAR=y
    BR2_TOOLCHAIN_BUILDROOT_CXX=y
    BR2_PACKAGE_FFMPEG=y
    BR2_PACKAGE_FFMPEG_GPL=y
    BR2_PACKAGE_FFMPEG_POSTPROC=y
    BR2_PACKAGE_FFMPEG_SWSCALE=y
    BR2_PACKAGE_VLC=y

This patch can be removed when vlc is bumped to 3.x.
