VideoFrameVulkan class

Access to a sender-owned Vulkan frame. The library owns the native frame; this object is valid until the next GetVulkanFrame call on the same sender or the sender's disposal. Before showing a frame, write the layouts and queue families the images were left in and the synchronization objects with VideoFrameVulkan.SetTextureState and VideoFrameVulkan.SetSynchronization.
