patch to gst to add export of DMA fd of input port
This patch adds h264 decode plugin using DMA for gstreamer. This plugin is supposed to be used to encode video data for CES2017 cluster demo. Change-Id: I19e3595aac8943ce3f348764aca66d2b4132cf28 Signed-off-by: Grigory Kletsko <grigory.kletsko@cogentembedded.com>
