* avutil/hwcontext_cuda: Only handle CUDA hardware framesTimo Rothenpieler2020-04-06

* avutil/hwcontext_cuda: combine transfer functionsTimo Rothenpieler2020-03-19
| | | | | Gets rid of some mostly duplicated code and adds the ability to do hardware to hardware transfers.
* avutil/hwcontext_cuda: add YUVA420P pixel formatYaroslav Pogrebnyak2020-03-19

* lavu/hwcontext_cuda: refactor context initialisationPhilip Langdale2020-02-04
| | | | | There's enough going on here now that it should not be duplicated between cuda_device_create and cuda_device_derive.
* lavu: add Vulkan hwcontext codeLynne2020-02-04
| | | | | | | | | | 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.

* avutil/hcontext_cuda: Remove unnecessary stream synchronisationPhilip Langdale2019-03-30
| | | | | | | 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.
* avutil/hwcontext_cuda: Define and use common CHECK_CU()Philip Langdale2018-11-14
| | | | | | | | | | | | | | | | | | 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

| | | | | CUVID is now capable of returning 10bit and 12bit decoded content in P010/P016. Let's support transfering those formats.
