Lynne	d8f301cdf2	ffv1enc_vulkan: switch to receive_packet ... This allows the encoder to fully saturate all queues the GPU has, giving a good 10% in certain cases and resolutions. This also improves error resilience if an allocation fails, and properly cleans up after itself if it does.	2024-11-26 14:14:15 +01:00
Lynne	e3676d96cb	hwcontext_vulkan: move device feature struct setup to a new function	2024-10-04 10:10:43 +02:00
Lynne	535e5eb7f3	hwcontext_vulkan: enable VK_KHR_shader_relaxed_extended_instruction	2024-10-04 10:10:43 +02:00
Lynne	0d5bfd0b21	vulkan_functions: change extension type to a typedef uint64_t ... We were getting a bit too close for comfort to the 32-bit limit on enums.	2024-10-04 10:10:42 +02:00
Lynne	37d5cb84e8	vulkan: check if current buffer has finished execution before picking another ... This saves resources, as dependencies are freed/reclaimed with a lower latency, and provies a speedup.	2024-10-04 10:10:42 +02:00
Lynne	bc36fe6f1f	vulkan: use push descriptors where possible ... Push descriptors are in theory slightly faster, but come with limitations for which we have to check. Either way, they're not difficult to implement, so even though no one should be using peasant-tier descriptors, do it anyway.	2024-09-23 13:41:07 +02:00
Lynne	8a7af4aa49	vulkan: add support for regular descriptor pools ... This permits: - The use of Vulkan filtering on many more devices - Better debugging due to lack of descriptor buffer support in layers Much of the changes here are due to a requirement that updates to descriptors must happen between the command buffer being waited on, and the pipeline not being bound. We routinely did it the other way around, by updating only after we bind the pipeline.	2024-09-23 13:40:38 +02:00
Lynne	a577d313b2	hwcontext_vulkan: add support for implicit DRM synchronization ... More recent kernel versions allow for users to extract a sync_file handle from a DMA-BUF, which can then be imported into Vulkan as a binary semaphore. This finally allows for synchronization between Vulkan and DMA-BUF images, such as those from screen capture software, or VAAPI, avoiding any corruption artifacts. This is done fully asynchronously, where we use the kernel's given binary semaphores as a dependency to increment the image's usual VkSemaphores we allocate. The old imported binary semaphores are cleaned up after execution as usual. In the future, hwcontext_drm should receive support for explicitly synchronized images as well, which would make the synchronization more robust and portable.	2024-09-22 02:11:08 +02:00
Lynne	46c13834b6	hwcontext_vulkan: enable VK_KHR_video_maintenance1 ... We require it for encoding.	2024-08-16 01:22:15 +02:00

Lynne	55adcb4fc5	hwcontext_vulkan: add support for VK_EXT_shader_object ... We'd like to use it eventually, and its already covered by the minimum version of the headers we require.	2024-08-11 05:13:13 +02:00
Lynne	a30b7c0158	hwcontext_vulkan: initialize optical flow queues if available ... Lets us implement FPS conversion.	2024-08-11 05:13:10 +02:00
Lynne	ecdc94b97f	vulkan_av1: port to the new stable API ... Co-Authored-by: Dave Airlie <airlied@redhat.com>	2024-03-25 08:54:40 +01:00
Lynne	358919506d	vulkan: enable VK_KHR_cooperative_matrix ... It's of interest to API users, and of interest to us, as a DCT/DST can be implemented via matrix multiplies.	2023-08-26 23:14:53 +02:00

Lynne	77478f6793	av1dec: add Vulkan hwaccel	2023-05-29 00:42:00 +02:00
Lynne	b5eaeb1f13	vulkan: rewrite to support all necessary features ... This commit rewrites the majority of vulkan.c to enable its use as a general-purpose high-level utility code, usable for decoding, encoding, and filtering of video frames. The dependency system was rewritten to simplify management of execution. The image handling system was rewritten to accomodate multiplane images. Due to how related all the new features were, this is a single commit.	2023-05-29 00:41:48 +02:00

Lynne	571756bf2f	hwcontext_vulkan: use VK_EXT_physical_device_drm to derive DRM to Vulkan ... Finally, a way to directly identify a Vulkan device from a DRM device!	2023-05-29 00:41:40 +02:00

Lynne	3c831847a8	hwcontext_vulkan: avoid using 64-bit enums ... MSVC (2016, but possibly more) still force enums to be basic ints.	2022-01-27 10:27:09 +01:00
Wu Jianhua	b3624069f0	avutil/hwcontext_vulkan: fully support customizable validation layers ... Validation layer is an indispensable part of developing on Vulkan. The following commands is on how to enable validation layers: ffmpeg -init_hw_device vulkan=0,debug=1,validation_layers=VK_LAYER_LUNARG_monitor+VK_LAYER_LUNARG_api_dump Signed-off-by: Wu Jianhua <jianhua.wu@intel.com>	2021-11-26 10:36:39 +01:00

Lynne	57e11321ea	hwcontext_vulkan: use vkDeviceWaitIdle instead of vkWaitSemaphores on uninit ... To silence a possible validation layer bug, switch the function. It only gets triggered by vf_libplacebo, which is odd.	2021-11-12 14:45:17 +01:00
Lynne	d05a18cdc7	lavu: move hwcontext_vulkan's function loader into separate files ... This allows for the loader to be shared with libavcodec and libavfilter.	2021-11-12 05:23:40 +01:00
