It's been returning an error value since bad446e251405dc250c3cbee199072e083a1e4b9 Also check for the errors it returns. --- libavcodec/h264.c | 4 +++- libavcodec/h264.h | 2 +- libavcodec/h264_refs.c | 12 ++++++++---- 3 files changed, 12 insertions(+), 6 deletions(-) (limited to 'libavcodec') diff --git a/libavcodec/h264.c b/libavcodec/h264.c index d2bbe465eb..3298565d97 100644 --- a/libavcodec/h264.c +++ b/libavcodec/h264.c @@ -2904,7 +2904,9 @@ static int decode_slice_header(H264Context *h, H264Context *h0) s->current_picture_ptr->frame_num = h->prev_frame_num; ff_thread_report_progress(&s->current_picture_ptr->f, INT_MAX, 0); ff_thread_report_progress(&s->current_picture_ptr->f, INT_MAX, 1); - ff_generate_sliding_window_mmcos(h, 1); + if ((ret = ff_generate_sliding_window_mmcos(h, 1)) < 0 && + s->avctx->err_recognition & AV_EF_EXPLODE) + return ret; if (ff_h264_execute_ref_pic_marking(h, h->mmco, h->mmco_index) < 0 && (s->avctx->err_recognition & AV_EF_EXPLODE)) return AVERROR_INVALIDDATA; diff --git a/libavcodec/h264.h b/libavcodec/h264.h index ad4732e1df..898ebf7b0a 100644 --- a/libavcodec/h264.h +++ b/libavcodec/h264.h @@ -648,7 +648,7 @@ int ff_h264_execute_ref_pic_marking(H264Context *h, MMCO *mmco, int mmco_count); int ff_h264_decode_ref_pic_marking(H264Context *h, GetBitContext *gb, int first_slice); -void ff_generate_sliding_window_mmcos(H264Context *h, int first_slice); +int ff_generate_sliding_window_mmcos(H264Context *h, int first_slice); /** * Check if the top & left blocks are available if needed & change the diff --git a/libavcodec/h264_refs.c b/libavcodec/h264_refs.c index 62c2a5758e..0e4bd76931 100644 --- a/libavcodec/h264_refs.c +++ b/libavcodec/h264_refs.c @@ -488,7 +488,7 @@ static int check_opcodes(MMCO *mmco1, MMCO *mmco2, int n_mmcos) return 0; } -void ff_generate_sliding_window_mmcos(H264Context *h, int first_slice) +int ff_generate_sliding_window_mmcos(H264Context *h, int first_slice) { MpegEncContext * const s = &h->s; MMCO mmco_temp[MAX_MMCO_COUNT], *mmco = first_slice ? h->mmco : mmco_temp; @@ -521,6 +521,7 @@ void ff_generate_sliding_window_mmcos(H264Context *h, int first_slice) mmco_index, h->mmco_index, i); return AVERROR_INVALIDDATA; } + return 0; } int ff_h264_execute_ref_pic_marking(H264Context *h, MMCO *mmco, int mmco_count){ @@ -686,7 +687,7 @@ int ff_h264_decode_ref_pic_marking(H264Context *h, GetBitContext *gb, int first_slice) { MpegEncContext * const s = &h->s; - int i; + int i, ret; MMCO mmco_temp[MAX_MMCO_COUNT], *mmco = first_slice ? h->mmco : mmco_temp; int mmco_index = 0; @@ -743,8 +744,11 @@ int ff_h264_decode_ref_pic_marking(H264Context *h, GetBitContext *gb, } mmco_index = i; } else { - if (first_slice) - ff_generate_sliding_window_mmcos(h, first_slice); + if (first_slice) { + ret = ff_generate_sliding_window_mmcos(h, first_slice); + if (ret < 0 && s->avctx->err_recognition & AV_EF_EXPLODE) + return ret; + } mmco_index = -1; } } -- cgit v1.2.3
