FFmpeg Merges Implicit DRM Synchronization For Vulkan
Following Vulkan Video H.264/H.265 video encoder support being merged into the FFmpeg library, the latest improvement for this open-source multimedia API when leveraging Vulkan is implicit DRM synchronization.
"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.
