The old behavior worked with one-way VAAPI and DMABUF imports, but was broken with clients like wlroots' dmabuf-capture.	5 years ago
Lynne	501bd57bdb	hwcontext_vulkan: initialize semaphores of DMABUF imports There was a recent change in Intel's driver that triggered a driver-internal error if the semaphore given to the command buffer wasn't initialized. Given that the specifications require the semaphore to be initialized, this is within spec. Unlike what's causing it in the first place, which is that there are no ways to extract/import dma sync objects from DMABUFs, so we must leave our semaphores bare.	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
