gstreamer skylake error: failed to get surface available

[vandanachadha]

We have skylake and were able to reun the intel media sdk tests after installing that.

We then installed gstreamer using gst-build with enabled msdk.  However, this pipeline is not working ok:

gst-launch-1.0 --gst-debug=3 filesrc location=~/sample_videos/big_buck_bunny_720p_2mb.mp4 ! decodebin name=demux demux. ! queue ! audioresample ! audioconvert ! avenc_aac bitrate=192000 ! mux. mpegtsmux bitrate=5000000 alignment=7 name=mux ! filesink location=msdk_out_file_210308.ts demux. ! queue ! msdkh264enc hardware=true ! video/x-h264,stream-format=byte-stream,profile=high ! h264parse ! mux.
