From: Aman Gupta <aman@tmm1.net> This allows decode_slice to be invoked multiple times before end_frame, causing slices to accumulate before being fed into the VT decoder. An upcoming commit will re-use decode_slice for SPS and PPS nalus, so they can be propagated into the VT decoder session along with slide data. --- libavcodec/videotoolbox.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/libavcodec/videotoolbox.c b/libavcodec/videotoolbox.c index 8ed56392cc..1de556f3e8 100644 --- a/libavcodec/videotoolbox.c +++ b/libavcodec/videotoolbox.c @@ -141,8 +141,6 @@ int ff_videotoolbox_h264_start_frame(AVCodecContext *avctx, VTContext *vtctx = avctx->internal->hwaccel_priv_data; H264Context *h = avctx->priv_data; - vtctx->bitstream_size = 0; - if (h->is_avc == 1) { return videotoolbox_buffer_copy(vtctx, buffer, size); } @@ -441,8 +439,10 @@ static int videotoolbox_h264_end_frame(AVCodecContext *avctx) { H264Context *h = avctx->priv_data; AVFrame *frame = h->cur_pic_ptr->f; - - return videotoolbox_common_end_frame(avctx, frame); + VTContext *vtctx = avctx->internal->hwaccel_priv_data; + int ret = videotoolbox_common_end_frame(avctx, frame); + vtctx->bitstream_size = 0; + return ret; } static int videotoolbox_mpeg_start_frame(AVCodecContext *avctx, -- 2.13.5 (Apple Git-94)
