Chiebot-Mirror/FFmpeg - FFmpeg - Gitea: Git with a cup of tea

Author	SHA1	Message	Date
Lynne	2c6366590e	hwcontext_vulkan: do not OR the user-specified usage with our default flags Some users may need special formats that aren't available when the STORAGE flag bit is set, which would result in allocations failing.	5 years ago
Lynne	c6df64035f	hwcontext_vulkan: improve public header documentation Some things like using ImageLists were from a really old version that still used multiplanar images.	5 years ago
Lynne	ea1a7f6064	hwcontext_vulkan: expose the enabled device features With this, the puzzle of making libplacebo, ffmpeg and any other Vulkan API users interoperable is complete. Users of both libraries can initialize one another's contexts without having to create a new one.	5 years ago
Lynne	01c7539f30	hwcontext_vulkan: expose the amount of queues for each queue family This, along with the next patch, are the last missing pieces to being interoperable with libplacebo.	5 years ago
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	875c1707e5	hwcontext_vulkan: create all images with concurrent sharing mode As it turns out, we were already assuming and treating all images as if they had concurrent access mode. This just changes the flag to CONCURRENT, which has less restrictions than EXCLUSIVE, and fixed validation messages on machines with multiple queues. The validation layer didn't pick this up because the machine I was testing on had only a single queue.	5 years ago
Lynne	dccd07f66d	hwcontext_vulkan: expose enabled device and instance extensions This solves a huge oversight - it lets users reliably use their own AVVulkanDeviceContext. Otherwise, the extensions supplied and enabled are not discoverable by anything outside of hwcontext_vulkan. Also clarifies that any user-supplied VkInstance must be at least 1.1.	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	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
