From 67a4755b97de8fe0e22e25ff4714c76a5b570b44 Mon Sep 17 00:00:00 2001 From: Lynne <dev@lynne.ee> Date: Tue, 6 Jun 2023 12:48:11 +0200 Subject: [PATCH] hevcdec: remove redundant bits_used_for_short_term_rps field It was introduced for Vulkan, but it is equivalent to short_term_ref_pic_set_size when !short_term_ref_pic_set_sps_flag, and when !!short_term_ref_pic_set_sps_flag, Vulkan hardcodes a zero anyway. --- libavcodec/hevcdec.c | 1 - libavcodec/hevcdec.h | 1 - libavcodec/vulkan_hevc.c | 2 +- 3 files changed, 1 insertion(+), 3 deletions(-) diff --git a/libavcodec/hevcdec.c b/libavcodec/hevcdec.c index eee77ec4db..a4284921cb 100644 --- a/libavcodec/hevcdec.c +++ b/libavcodec/hevcdec.c @@ -723,7 +723,6 @@ static int hls_slice_header(HEVCContext *s) if (ret < 0) return ret; - sh->bits_used_for_short_term_rps = pos - get_bits_left(gb); sh->short_term_rps = &sh->slice_rps; } else { int numbits, rps_idx; diff --git a/libavcodec/hevcdec.h b/libavcodec/hevcdec.h index 04ec25d540..94609e4699 100644 --- a/libavcodec/hevcdec.h +++ b/libavcodec/hevcdec.h @@ -268,7 +268,6 @@ typedef struct SliceHeader { ///< RPS coded in the slice header itself is stored here int short_term_ref_pic_set_sps_flag; - int bits_used_for_short_term_rps; int short_term_ref_pic_set_size; ShortTermRPS slice_rps; const ShortTermRPS *short_term_rps; diff --git a/libavcodec/vulkan_hevc.c b/libavcodec/vulkan_hevc.c index c9b6888410..dcf7e75bc5 100644 --- a/libavcodec/vulkan_hevc.c +++ b/libavcodec/vulkan_hevc.c @@ -788,7 +788,7 @@ static int vk_hevc_start_frame(AVCodecContext *avctx, .NumDeltaPocsOfRefRpsIdx = h->sh.short_term_rps ? h->sh.short_term_rps->rps_idx_num_delta_pocs : 0, .PicOrderCntVal = h->poc, .NumBitsForSTRefPicSetInSlice = !h->sh.short_term_ref_pic_set_sps_flag ? - h->sh.bits_used_for_short_term_rps : 0, + h->sh.short_term_ref_pic_set_size : 0, }; /* Fill in references */ -- 2.40.1
