[FFmpeg-devel] [PATCH 1/3] lavu/hwcontext_vaapi: Add a new quirk

["Xiang, Haihao" <haihao.xiang-at-intel.com@ffmpeg.org>]

From: Haihao Xiang <haihao.xiang@intel.com>

libva2 doesn't require a fixed surface-array any more, but some
driver/hardware combinations which rely on this are still used. To
reduce the impact to users, add a quirk for the driver/hardware
combination which supports dynamic surface pool.
