Thank you so much! We will test this hopefully today, and verify the expected behavior with NSIGHT.

And the CUstream can be set and will be passed on to cuvid/nvdec. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
