Hi,
I’ve developed a decoding solution for H264 network streaming and rendering with D3D11, and everything looked to work fine at first, until I noticed a frustrating difference in framerate between my component and D3D11Decode sample. While the sample gives me nice ~40 fps on decoding 4k video, my app struggles at 3-4 fps. So, I drilled down to time each and every call in the pipeline and it appears, that the call to cuvidMapVideoFrame takes ~235-250 ms!!! It makes no sense at all, since my code is based upon the sample. I’m absolutely stuck here, since no similar issues were found on internet. Please help!
