public class VkVideoEncodeH264CapabilitiesEXT extends org.lwjgl.system.Struct<VkVideoEncodeH264CapabilitiesEXT> implements org.lwjgl.system.NativeResource
Structure specifying H.264 encode capabilities.
Description

When GetPhysicalDeviceVideoCapabilitiesKHR is called to query the capabilities with parameter videoCodecOperation specified as VIDEO_CODEC_OPERATION_ENCODE_H264_BIT_EXT, a VkVideoEncodeH264CapabilitiesEXT structure can be chained to VkVideoCapabilitiesKHR to retrieve H.264 extension specific capabilities.
