public class VkVideoEncodeInfoKHR extends org.lwjgl.system.Struct<VkVideoEncodeInfoKHR> implements org.lwjgl.system.NativeResource
Structure to chain codec-specific structures to.
Description

The coded size of the encode operation is specified in codedExtent of srcPictureResource.

Multiple CmdEncodeVideoKHR commands may be recorded within a Vulkan Video Encode Context. The execution of each CmdEncodeVideoKHR command will result in generating codec-specific bitstream units. These bitstream units are generated consecutively into the bitstream buffer specified in dstBuffer of a VkVideoEncodeInfoKHR structure within the CmdBeginVideoCodingKHR command. The produced bitstream is the sum of all these bitstream units, including any padding between the bitstream units. Any bitstream padding must be filled with data compliant to the codec standard so as not to cause any syntax errors during decoding of the bitstream units with the padding included. The range of the bitstream buffer written can be queried via video encode feedback queries.

Valid Usage
  • The bound video session must not be in uninitialized state at the time the command is executed on the device

    • VkVideoEncodeInfoKHR

      public VkVideoEncodeInfoKHR(ByteBuffer container)
      Creates a VkVideoEncodeInfoKHR 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.
