Philip Langdale	7f149b0452	lavu/hwcontext_cuda: refactor context initialisation There's enough going on here now that it should not be duplicated between cuda_device_create and cuda_device_derive.	5 years ago
Lynne	a88449ffb2	lavu: add Vulkan hwcontext code This commit adds the necessary code to initialize and use a Vulkan device within the hwcontext libavutil framework. Currently direct mapping to VAAPI and DRM frames is functional, and transfers to CUDA and native frames are supported. Lets hope the future Vulkan video decode extension fits well within this framework.	5 years ago
Oleg Dobkin	32ba563cfc	avutil/hwcontext_cuda: allow using primary CUDA device context Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>	5 years ago
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
