From b2e89bd9c548d899ec2fecfc1aa550e9ddfe9777 Mon Sep 17 00:00:00 2001

Subject: [PATCH] dxva2_hevc: don't use frames as reference if they are not
marked as such
Similar to how a frame is considered for referencing for the RefPicList array.
This will do the same for RefPicSetStCurrBefore, RefPicSetStCurrAfter and
RefPicSetLtCurr.
Fixes playback of http://www.gbbsoft.pl/!download/!/Film1.mp4
Ref. VLC issue https://code.videolan.org/videolan/vlc/-/issues/26738
