Direct rendering capable decoders call get_buffer() which will set the frame parameters.
Prevents frames with wrong parameters when a decoder outputs delayed frames after a resolution or pixel format change. --- Using CODEC_CAP_DR1 instead of CODEC_CAP_DELAY. get_buffer() sets the frame parameters already libavcodec/utils.c | 13 ++++++++----- 1 file changed, 8 insertions(+), 5 deletions(-) diff --git a/libavcodec/utils.c b/libavcodec/utils.c index 1185a35..b226ac0 100644 --- a/libavcodec/utils.c +++ b/libavcodec/utils.c @@ -1282,11 +1282,14 @@ int attribute_align_arg avcodec_decode_video2(AVCodecContext *avctx, AVFrame *pi else { ret = avctx->codec->decode(avctx, picture, got_picture_ptr, avpkt); - picture->pkt_dts = avpkt->dts; - picture->sample_aspect_ratio = avctx->sample_aspect_ratio; - picture->width = avctx->width; - picture->height = avctx->height; - picture->format = avctx->pix_fmt; + picture->pkt_dts = avpkt->dts; + /* get_buffer is supposed to set frame parameters */ + if (!(avctx->codec->capabilities & CODEC_CAP_DR1)) { + picture->sample_aspect_ratio = avctx->sample_aspect_ratio; + picture->width = avctx->width; + picture->height = avctx->height; + picture->format = avctx->pix_fmt; + } } emms_c(); //needed to avoid an emms_c() call before every return; -- 1.7.12.4 _______________________________________________ libav-devel mailing list libav-devel@libav.org https://lists.libav.org/mailman/listinfo/libav-devel
