public class VkVideoProfileInfoKHR extends org.lwjgl.system.Struct<VkVideoProfileInfoKHR> implements org.lwjgl.system.NativeResource
Structure specifying a video profile.
Description

Video profiles are provided as input to video capability queries such as GetPhysicalDeviceVideoCapabilitiesKHR or GetPhysicalDeviceVideoFormatPropertiesKHR, as well as when creating resources to be used by video coding operations such as images, buffers, query pools, and video sessions.

The full description of a video profile is specified by an instance of this structure, and the codec-specific and auxiliary structures provided in its pNext chain.

When this structure is specified as an input parameter to GetPhysicalDeviceVideoCapabilitiesKHR, or through the pProfiles member of a VkVideoProfileListInfoKHR structure in the pNext chain of the input parameter of a query command such as GetPhysicalDeviceVideoFormatPropertiesKHR or GetPhysicalDeviceImageFormatProperties2, the following error codes indicate specific causes of the failure of the query operation:

Valid Usage
Valid Usage (Implicit)
  • sType must be STRUCTURE_TYPE_VIDEO_PROFILE_INFO_KHR
  • videoCodecOperation must be a valid VkVideoCodecOperationFlagBitsKHR value
  • chromaSubsampling must be a valid combination of VkVideoChromaSubsamplingFlagBitsKHR values
  • chromaSubsampling must not be 0
  • lumaBitDepth must be a valid combination of VkVideoComponentBitDepthFlagBitsKHR values
  • lumaBitDepth must not be 0
  • chromaBitDepth must be a valid combination of VkVideoComponentBitDepthFlagBitsKHR values

    • VkVideoProfileInfoKHR

      public VkVideoProfileInfoKHR(ByteBuffer container)
      Creates a VkVideoProfileInfoKHR 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.
