From 85cc7bcd4cf1e1963c22c1ea1594160a33da4fee Mon Sep 17 00:00:00 2001 From: Linjie Fu Date: Wed, 15 Jan 2020 15:01:42 +0800 Subject: lavc/vaapi_hevc: add function to find exact va_profile for REXT Add vaapi_parse_rext_profile and use profile constraint flags to determine the exact va_profile for HEVC_REXT. If profile mismatch is allowed, select Main profile by default. Add build object in Makefile for h265_profile_level dependency.
