From 1054752c563cbe978f16010ed57dfa23a41ee490 Mon Sep 17 00:00:00 2001 From: ManojGuptaBonda Date: Fri, 25 Oct 2019 11:00:13 +0530 Subject: [PATCH] Add support for VP9 VDPAU hwaccel decode Support for VDPAU accelerated VP9 decoding was added with libvdpau-1.3. Support for the same in ffmpeg is added with this patch. Profiles related to VDPAU VP9 can be found in latest vdpau.h present in libvdpau-1.3. DRC clips are not supported yet due to http://trac.ffmpeg.org/ticket/8068 Add VP9 VDPAU to list of hwaccels and supported formats Added file vdpau_vp9.c and Modified configure to add VDPAU VP9 support. Mapped VP9 profiles to VDPAU VP9 profiles. Populated the codec specific params that need to be passed to VDPAU.
