Re: [FFmpeg-devel] [PATCH 3/6] avutil/hwcontext_cuda: add CUstream in cuda hwctx

What is this? https://docs.nvidia.com/cuda/cuda-driver-api/stream-sync-behavior.html It allows asynchronous processing of CUDA workloads. The next couple patches make use of it. There's no change in behaviour if it remains unset/NULL, but if you set one, the workload won't block the main CUDA
