avcodec/cuviddec: Remove unnecessary stream synchronisation We're also doing a sync here after copying the frame to be passed on down the pipleine. And it is also unnecessary. I was able to demonstrate a 33% speedup removing the sync from an example transcode pipeline. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=5d90d1e36ef3abfa2843e54389d0ffd0fa7ca405 --- libavcodec/cuviddec.c | 4 ---- 1 file changed, 4 deletions(-) diff --git a/libavcodec/cuviddec.c b/libavcodec/cuviddec.c index 291bb93dbc..2aecb45768 100644 --- a/libavcodec/cuviddec.c +++ b/libavcodec/cuviddec.c @@ -553,10 +553,6 @@ static int cuvid_output_frame(AVCodecContext *avctx, AVFrame *frame) offset += height; } - - ret = CHECK_CU(ctx->cudl->cuStreamSynchronize(device_hwctx->stream)); - if (ret < 0) - goto error; } else if (avctx->pix_fmt == AV_PIX_FMT_NV12 || avctx->pix_fmt == AV_PIX_FMT_P010 || avctx->pix_fmt == AV_PIX_FMT_P016 || _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email ffmpeg-cvslog-requ...@ffmpeg.org with subject "unsubscribe".
