Re: [FFmpeg-devel] [PATCH] nvenc set slice number to 1 to improve encoding quality and clamp initial qp value to [1, 51]

performance that impacts some higher resolutions which can't be encoded in realtime anymore. If that's not the case, this LGTM. No, it won't affect performance, we did lots of internal tests, mainly focused on quality improvement. But if it makes performance worse we won't apply it anyway. Agatha Hu

It's the creation flag of cuCtxCreate, currently is 0(default) which will cause CPU thread spins when waiting for GPU to return thus decrease the CPU performance.
