Module: libav Branch: master Commit: cad739dace55e3446ef7180de688173cd19fb000
Author: Mark Thompson <[email protected]> Committer: Mark Thompson <[email protected]> Date: Mon Jan 29 22:55:11 2018 +0000 lavc: Add per-thread surfaces in get_hw_frame_parameters() This number is definitely required when frame threading is enabled, so add it here rather than forcing all users to handle it themselves. DXVA2 contained this addition in specific code as well (therefore being added twice in the internal case) - just remove it from there. --- libavcodec/decode.c | 9 +++++---- libavcodec/dxva2.c | 4 ---- 2 files changed, 5 insertions(+), 8 deletions(-) diff --git a/libavcodec/decode.c b/libavcodec/decode.c index e024a32..8635aec 100644 --- a/libavcodec/decode.c +++ b/libavcodec/decode.c @@ -748,10 +748,6 @@ int ff_decode_get_hw_frames_ctx(AVCodecContext *avctx, // We guarantee 4 base work surfaces.
