Philip Langdale	52d8f35b14	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.	6 years ago
Philip Langdale	19d3d0c057	avutil/hwcontext_cuda: Define and use common CHECK_CU() We have a pattern of wrapping CUDA calls to print errors and normalise return values that is used in a couple of places. To avoid duplication and increase consistency, let's put the wrapper implementation in a shared place and use it everywhere. Affects: * avcodec/cuviddec * avcodec/nvdec * avcodec/nvenc * avfilter/vf_scale_cuda * avfilter/vf_scale_npp * avfilter/vf_thumbnail_cuda * avfilter/vf_transpose_npp * avfilter/vf_yadif_cuda	6 years ago
