ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Fri Sep 30 21:21:46 2016 +0200| [775a8477b74bb2fa95ca2b13c08f3fd8d6c617b6] | committer: Mark Thompson

hwcontext_vaapi: add a quirk for the missing MemoryType attribute

The Intel binary iHD driver does not support the
VASurfaceAttribMemoryType, so surface allocation will fail when using
it.

(cherry picked from commit 2124711b950b03c582a119c75f52a87acc32d6ec)
