	I'm trying to use h264_qsv decoder with ffplay 2.8 and my Core
i7 2700k and I get "Error initializing an internal MFX session".

	I attached the complete output of -report.

	I'm afraid mfx_dispatch only works with 3rd generation Intel
processors and above, right?

	Here's the output of vainfo:

	I can play the same H264 video using gst-play from Gstreamer using hardware
