* avutil/hwcontext_cuda: increase CUDA frame alignment to 512Timo Rothenpieler2020-11-03
| | | | | At least on Turing, a frame without 512 byte alignment cannot be passed to cuTexObjectCreate.
* hwcontext: add av_hwdevice_ctx_create_derived_optsLynne2020-05-23
| | | | | | | | | | | | | This allows for users who derive devices to set options for the new device context they derive. The main use case of this is to allow users to enable extensions (such as surface drawing extensions) in Vulkan while deriving from the device their frames are on. That way, users don't need to write any initialization code themselves, since the Vulkan spec invalidates mixing instances, physical devices and active devices. Apart from Vulkan, other hwcontexts ignore the opts argument since they don't support options at all (or in VAAPI and OpenCL's case, options are currently only used for device selection, which device_derive overrides).
* 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.

* 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
