* hwcontext_vulkan: use VkPhysicalDeviceTimelineSemaphoreFeaturesZhao Zhili2022-02-01
| | | | | | | VkPhysicalDeviceVulkan12Features isn't implemented on MoltenVK yet. VkPhysicalDeviceTimelineSemaphoreFeatures is less versatile but simple. None of device_features_1_1 nor device_features_1_2 has real usage yet, keep the code for future.

* hwcontext_vulkan: remove VK_EXT_hdr_metadata from autoloaded extensions listLynne2022-01-03
| | | | | | We don't use it. Was copied from libplacebo's recommended defaults. Creates problems with validation on Intel devices, where the driver still advertizes it, even though it's not usable without a swapchain.
* hwcontext_vulkan: wait on semaphores when exporting to DRMLynne2021-12-10
| | | | There is no synchronization method for DRM yet.
* hwcontext_vulkan: support creating DRM-tiled images and autodetecting modifiersWenbin Chen2021-12-10
| | | | | | | | | | | | | | | When vulkan image exports to drm, the tilling need to be VK_IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT. Now add code to create vulkan image using this format. Now the following command line works: ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format \ vaapi -i input_1080p.264 -vf "hwmap=derive_device=vulkan,format=vulkan, \ scale_vulkan=1920:1080,hwmap=derive_device=vaapi,format=vaapi" -c:v h264_vaapi output.264 Signed-off-by: Wenbin Chen <wenbin.chen@intel.com> Further-modifications-by: Lynne <dev@lynne.ee>
* hwcontext_vulkan: add support for mapping frames with planes in a single ↵Wenbin Chen2021-12-10

* hwcontext_vulkan: add support for allocating all planes in a single allocationWenbin Chen2021-12-10
| | | | | | | | | | | | | | VAAPI on Intel can import external frame, but the planes of the external frames should be in the same drm object. A new option "contiguous_planes" is added to device. This flag tells device to allocate places in one memory. When device is derived from vaapi this flag will be enabled. A new flag frame_flag is also added to AVVulkanFramesContext. User can use this flag to force enable or disable this behaviour. A new variable "offset "is added to AVVKFrame. It describe describe the offset from the memory currently bound to the VkImage.

* hwcontext_vulkan: check for non-flagged transfer queue familiesLynne2021-11-20
| | | | | | | | | "All commands that are allowed on a queue that supports transfer operations are also allowed on a queue that supports either graphics or compute operations. Thus, if the capabilities of a queue family include VK_QUEUE_GRAPHICS_BIT or VK_QUEUE_COMPUTE_BIT, then reporting the VK_QUEUE_TRANSFER_BIT capability separately for that queue family is optional."

* hwcontext_vaapi: don't use the generic mapping struct for DRM/VAAPILynne2021-11-13
| | | | Avoids a per-frame allocation since we don't need the flag field.
* hwcontext_vulkan: fix small memory leak when unmappingLynne2021-11-13

* hwcontext_vulkan: wait for semaphores when unmapping from VAAPILynne2021-11-13
| | | | | We don't really want to do a full all-queue blocking wait here, since this happens once per frame, and this could delay future frames.
* hwcontext_vulkan: print error information on queue submission failureLynne2021-11-13
| | | | Makes it clearer what went wrong.
* hwcontext_vulkan: fix DMABUF import format check callLynne2021-11-13
| | | | | VkExternalImageFormatProperties is required to be present in the .pNext chain of VkImageFormatProperties2, or some drivers crash (RADV).

| | | | Missing goto.
* hwcontext_vulkan: fix CreateSemaphore conflict with synchapi.hLynne2021-11-12
| | | | | | Include windows.h to fix it. Normally, it'd be better to include it in vulkan_functions.h, but I'm reasonably confident nothing else that uses the Vulkan code will need to include Windows functions and not windows.h.
* hwcontext_vulkan: use vkDeviceWaitIdle instead of vkWaitSemaphores on uninitLynne2021-11-12
| | | | | To silence a possible validation layer bug, switch the function. It only gets triggered by vf_libplacebo, which is odd.
* lavu: move hwcontext_vulkan's function loader into separate filesLynne2021-11-12
| | | | This allows for the loader to be shared with libavcodec and libavfilter.

| | | | Not sure why this wasn't done before.
* vulkan: add support for encode and decode queues and refactor queue codeLynne2021-11-12
| | | | | | | | | This simplifies and makes queue family picking simpler and more robust. The requirements on the device context are relaxed. They made no sense in the first place. The video encode/decode extension is still in beta, at least on paper, but I really doubt they'd change needing a separate queue family.

* hwcontext_vulkan: dlopen libvulkanLynne2021-04-30
| | | | | | | | | | | | While Vulkan itself went more or less the way it was expected to go, libvulkan didn't quite solve all of the opengl loader issues. It's multi-vendor, yes, but unfortunately, the code is Google/Khronos QUALITY, so suffers from big static linking issues (static linking on anything but OSX is unsupported), has bugs, and due to the prefix system used, there are 3 or so ways to type out functions. Just solve all of those problems by dlopening it. We even have nice emulation for it on Windows.

* hwcontext_vulkan: wait and signal semaphores when transferring to CUDALynne2020-12-05
| | | | | Same as when downloading. Not sure why this isn't done, probably because the CUDA code predates the sync mechanism we settled on.
* hwcontext_vulkan: reduce priority for PACK32 formatsLynne2020-11-27

* hwcontext_vulkan: optionally enable more functionalityNiklas Haas2020-11-25
| | | | | | These two extensions and two features are both optionally used by libplacebo to speed up rendering, so it makes sense for libavutil to automatically enable them as well.
