Timo Rothenpieler	2f3cb5ccca	avutil/hwcontext_cuda: query correct alignment from device	4 years ago
Timo Rothenpieler	d5763edab2	avutil/hwcontext_cuda: increase CUDA frame alignment to 512 At least on Turing, a frame without 512 byte alignment cannot be passed to cuTexObjectCreate.	4 years ago
Lynne	2e08b39444	hwcontext: add av_hwdevice_ctx_create_derived_opts 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).	5 years ago
Timo Rothenpieler	30b28f9a83	avutil/hwcontext_cuda: Only handle CUDA hardware frames	5 years ago
Timo Rothenpieler	d9a37af070	avutil/hwcontext_cuda: combine transfer functions Gets rid of some mostly duplicated code and adds the ability to do hardware to hardware transfers.	5 years ago
Yaroslav Pogrebnyak	08d46cb586	avutil/hwcontext_cuda: add YUVA420P pixel format Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>	5 years ago
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
