Lynne	97890c2b55	lavu/vulkan: remove threadsafe buffer index load and fix a signed overflow It's not needed anymore.	1 year ago
Lynne	5f1be341c2	vulkan: discard dependencies when explicitly waiting for execution This reduces memory needed dramatically, as unneeded resources can be immediately returned to the pool. Although waitforfences is threadsafe, we add a mutex wait around it, as the mutex fence in combination with waitforfences assures us that no other thread will reset the fence in the meanwhile whilst the mutex is locked. This allows is to call ff_vk_exec_discard_deps.	1 year ago
Lynne	975cd48bb3	vulkan: synchronize access to execution pool fences vkResetFences is specified as being user-synchronized (yet vkWaitFences, is not).	1 year ago

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.	1 year ago

Lynne	135e1c0adf	lavu/vulkan: check for initialization when freeing buffers What happens on startup is that ffmpeg.c initializes the filter, then frees it without feeding a single frame through. With no input frame, the filter lacks a hardware device. The rest of the uninit code checks if Vulkan objects exist, which they must if there's a hardware device, but vk->DeviceWaitIdle does not require an object. So, add a check for it.	3 years ago
Lynne	da72aca7b0	lavu/vulkan: add support for using libshaderc as a GLSL compiler It's got a much better API that's actually maintained, it eliminates race conditions, it comes with a pkg-config file by default, and unfortunately isn't currently packaged by Debian or other large distributions.	3 years ago
Lynne	f6dd30df24	lavfi/vulkan: split off lavfi-specific code into vulkan_filter.c The issue is that libavfilter depends on libavcodec, and when doing a static build, if libavcodec also includes "libavfilter/vulkan.c", then during link-time, compiling programs will fail as there would be multiple definitions of the same symbols in both libavfilter and libavcodec's object files. Linkers are, however, more permitting if both files that include a common file that's used as a template are one-to-one identical. Hence, to make both files the same in the future, export all avfilter specific functions to a separate file. There is some work in progress to make templated files like this be compiled only once, so this is not a long-term solution. This also removes a macro that could be used to toggle SPIRV compilation capability on #include-time, as this could cause the files to be different.	3 years ago
Lynne	b2aec70bd6	lavu/vulkan: add option to switch between shader compilers and cleanup glslang	3 years ago

Lynne	20c66fe2f9	lavfi/vulkan: fix issues the previous commit introduced One typo and one think-before-you-paste.	3 years ago
Lynne	8af7bcb6c3	lavfi/vulkan: add mutliqueue emulation code This helps with testing multiple queues when the hardware only has a single queue.	3 years ago
Lynne	8f9888a8d4	lavfi/vulkan: fix static descriptor set updating Update all descriptor sets for all queues if a descriptor set hasn't been initialized yet.	3 years ago
Lynne	f705e9ea05	lavfi/vulkan: refactor, fix and fully implement multiple queues	3 years ago
Lynne	246f841b53	lavfi/glslang: migrate to the C API and robustify library detection Finally, this is as close to usable as it gets for glslang. Much faster to compile as well, and eliminates the need for a C++ compiler, which is great. Also, changes to the resource limits won't break users, as we can use designated initializers in C90.	3 years ago
Lynne	fef85c376a	lavfi/vulkan: use libavutil's vulkan loader This finally fully eliminates the need to statically link to libvulkan!	3 years ago

Andreas Rheinhardt	4c0adcd07e	avfilter/vulkan: Store format in filter, remove query function Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	18ec426a86	avfilter/formats: Factor common function combinations out Several combinations of functions happen quite often in query_format functions; e.g. ff_set_common_formats(ctx, ff_make_format_list(sample_fmts)) is very common. This commit therefore adds functions that are equivalent to commonly used function combinations in order to reduce code duplication.

Lynne	70d396c8af	Revert "hwcontext_vulkan: only use one semaphore per image" This reverts commit `97b526c192`. It broke the API, and assumed no other APIs used multiple semaphores. This also disallowed certain optimizations to happen. Dealing with APIs that give or expect single semaphores is easier when we use per-image semaphores.	5 years ago
Lynne	97b526c192	hwcontext_vulkan: only use one semaphore per image The idea was to allow separate planes to be filtered independently, however, in hindsight, literaly nothing uses separate per-plane semaphores and it would only work when each plane is backed by separate device memory.	5 years ago
Lynne	1a5e9ae4d8	scale_vulkan: add support for RGB->YUV conversions Only top-left chroma position supported for now.	5 years ago
Lynne	6fca61bbc9	lavfi: add Vulkan filtering framework This commit adds a Vulkan filtering infrastructure for libavfilter. It attempts to abstract as much as possible of the Vulkan API from filters. The way the hwcontext and the framework are designed permits for parallel, non-CPU-blocking filtering throughout, with the exception of up/downloading and mapping.	5 years ago
