public class VkVideoCapabilitiesKHR extends org.lwjgl.system.Struct<VkVideoCapabilitiesKHR> implements org.lwjgl.system.NativeResource
Structure describing general video capabilities for a video profile.
Description
Note

It is common for video compression standards to allow using all reference pictures associated with active DPB slots as active reference pictures, hence for video decode profiles the values returned in maxDpbSlots and maxActiveReferencePictures are often equal. Similarly, in case of video decode profiles supporting field pictures the value of maxActiveReferencePictures often equals maxDpbSlots × 2.

    • VkVideoCapabilitiesKHR

      public VkVideoCapabilitiesKHR(ByteBuffer container)
      Creates a VkVideoCapabilitiesKHR instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.
