Enable zero-copy support for gstreamer video decoders

Multimedia / VLC - Vikram Fugro [gmail.com] - 5 February 2016 09:17 UTC

Implements the interface to provide the VLC pictures from vout mapped to GstBuffers, along with per video plane stride/offsets info, to the upstream gstreamer
video decoder. If the stride/offsets info of the vlc pictures (created by vout) matches the video decoder's expectations, the decoder will directly decode into the vout allocated pictures, enabling zero-copy. Else it will continue to use it's own bufferpool
