avutil/hcontext_cuda: Remove unnecessary stream synchronisation Similarly to the previous changes, we don't need to synchronise after a memcpy to device memory. On the other hand, we need to keep synchronising after a copy to host memory, otherwise there's no guarantee that subsequent host reads will return valid data. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=52d8f35b14bc379572e74d042d3466b8d3b6e7cf --- libavutil/hwcontext_cuda.c | 4 ---- 1 file changed, 4 deletions(-) diff --git a/libavutil/hwcontext_cuda.c b/libavutil/hwcontext_cuda.c index 540a7610ef..cca39e9fc7 100644 --- a/libavutil/hwcontext_cuda.c +++ b/libavutil/hwcontext_cuda.c @@ -268,10 +268,6 @@ static int cuda_transfer_data_to(AVHWFramesContext *ctx, AVFrame *dst, goto exit; } - ret = CHECK_CU(cu->cuStreamSynchronize(hwctx->stream)); - if (ret < 0) - goto exit; - exit: CHECK_CU(cu->cuCtxPopCurrent(&dummy)); _______________________________________________ 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".
