From e6b990e25d2b2f443faca10accc91e1e9b998e5a Mon Sep 17 00:00:00 2001 From: "Chen,Wenbin" Date: Fri, 12 Mar 2021 10:44:06 +0800 Subject: [PATCH] libavcodec/qsvdec.c: using queue count to unref frame MSDK vc1 and av1 sometimes output frame into the same suface, but ffmpeg-qsv assume the surface will be used only once, so it will unref the frame when it receives the output surface. Now change it to unref frame according to queue count.
