public class VkVideoEncodeH265RateControlInfoEXT
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure describing H.265 stream rate control parameters.
Description

In order to provide H.265-specific stream rate control parameters, add a VkVideoEncodeH265RateControlInfoEXT structure to the pNext chain of the VkVideoEncodeRateControlInfoKHR structure in the pNext chain of the VkVideoCodingControlInfoKHR structure passed to the CmdControlVideoCodingKHR command.

The parameters from this structure act as a guidance for implementations to apply various rate control heuristics.

It is possible to infer the picture type to be used when encoding a frame, on the basis of the values provided for consecutiveBFrameCount, idrPeriod, and gopFrameCount, but this inferred picture type will not be used by implementations to override the picture type provided in CmdEncodeVideoKHR. Additionally, it is not required for the video session to be reset if the inferred picture type does not match the actual picture type.

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_VIDEO_ENCODE_H265_RATE_CONTROL_INFO_EXT
- rateControlStructure must be a valid VkVideoEncodeH265RateControlStructureFlagBitsEXT value
Layout
```
 struct VkVideoEncodeH265RateControlInfoEXT {
     VkStructureType sType();
     void const * pNext();
     uint32_t gopFrameCount();
     uint32_t idrPeriod();
     uint32_t consecutiveBFrameCount();
     VkVideoEncodeH265RateControlStructureFlagBitsEXT rateControlStructure();
     uint8_t subLayerCount();
 }
