VkVideoSessionCreateInfoKHR

The VkVideoSessionCreateInfoKHR structure is defined as:

typedef struct VkVideoSessionCreateInfoKHR {
    VkStructureType sType;
    const void* pNext;
    uint32_t queueFamilyIndex;
    VkVideoSessionCreateFlagsKHR flags;
    const VkVideoProfileInfoKHR* pVideoProfile;
    VkFormat pictureFormat;
    VkExtent2D maxCodedExtent;
    VkFormat referencePictureFormat;
    uint32_t maxDpbSlots;
    uint32_t maxActiveReferencePictures;
    const VkExtensionProperties* pStdHeaderVersion;
} VkVideoSessionCreateInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• queueFamilyIndex is the index of the queue family the created video session will be used with.
• flags is a bitmask of VkVideoSessionCreateFlagBitsKHR specifying creation flags.
• pVideoProfile is a pointer to a VkVideoProfileInfoKHR structure specifying the video profile the created video session will be used with.
• pictureFormat is the image format the created video session will be used with. If pVideoProfile→videoCodecOperation specifies a decode operation, then pictureFormat is the image format of decode output pictures usable with the created video session. If pVideoProfile→videoCodecOperation specifies an encode operation, then pictureFormat is the image format of encode input pictures usable with the created video session.
• maxCodedExtent is the maximum width and height of the coded frames the created video session will be used with.
• referencePictureFormat is the image format of reference pictures stored in the DPB the created video session will be used with.
• maxDpbSlots is the maximum number of DPB Slots that can be used with the created video session.
• maxActiveReferencePictures is the maximum number of active reference pictures that can be used in a single video coding operation using the created video session.
• pStdHeaderVersion is a pointer to a VkExtensionProperties structure requesting the Video Std header version to use for the videoCodecOperation specified in pVideoProfile.
