Subject: [FFmpeg-devel] [PATCH 1/2] libavcodec/qsvenc_hevc: add tier option
Date: Wed, 2 Nov 2022 01:57:37 +0800
Message-ID: <20221101175738.21642-1-nst799610810@gmail.com> (raw)
Without this change, MSDK/VPL always defaults the HEVC tier to MAIN if the -level is specified.
Also, according to the HEVC specs, only level >= 4 can support High Tier.
