C Specification

When creating a Video Session object with VkVideoSessionCreateInfoKHR::pVideoProfile->videoCodecOperation specified as VK_VIDEO_CODEC_OPERATION_ENCODE_H265_BIT_EXT, add a VkVideoEncodeH265SessionCreateInfoEXT structure to the pNext chain of the VkVideoSessionCreateInfoKHR structure passed to vkCreateVideoSessionKHR in order to specify the H.265-specific video encoder session creation parameters.

The VkVideoEncodeH265SessionCreateInfoEXT structure is defined as:

// Provided by VK_EXT_video_encode_h265
typedef struct VkVideoEncodeH265SessionCreateInfoEXT {
    VkStructureType                    sType;
    const void*                        pNext;
    VkVideoEncodeH265CreateFlagsEXT    flags;
    const VkExtensionProperties*       pStdExtensionVersion;
} VkVideoEncodeH265SessionCreateInfoEXT;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • flags is reserved for future use.

  • pStdExtensionVersion is a pointer to a VkExtensionProperties structure specifying the H.265 codec extension version.

Description

Valid Usage (Implicit)

  • VUID-VkVideoEncodeH265SessionCreateInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H265_SESSION_CREATE_INFO_EXT

  • VUID-VkVideoEncodeH265SessionCreateInfoEXT-flags-zerobitmask
    flags must be 0

  • VUID-VkVideoEncodeH265SessionCreateInfoEXT-pStdExtensionVersion-parameter
    pStdExtensionVersion must be a valid pointer to a valid VkExtensionProperties structure
