VkVideoInlineQueryInfoKHR

The VkVideoInlineQueryInfoKHR structure is defined as:

typedef struct VkVideoInlineQueryInfoKHR {
    VkStructureType sType;
    const void* pNext;
    VkQueryPool queryPool;
    uint32_t firstQuery;
    uint32_t queryCount;
} VkVideoInlineQueryInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• queryPool is VK_NULL_HANDLE or a valid handle to a VkQueryPool object that will manage the results of the queries.
• firstQuery is the query index within the query pool that will contain the query results for the first video coding operation. The query results of subsequent video coding operations will be contained by subsequent query indices.
• queryCount is the number of queries to execute.

  In practice, if queryPool is not VK_NULL_HANDLE, then queryCount will always have to match the number of video coding operations issued by the video coding command this structure is specified to, meaning that using inline queries in a video coding command will always execute a query for each issued video coding operation.

This structure can be included in the pNext chain of the input parameter structure of video coding commands.

• In the pNext chain of the pDecodeInfo parameter of the vkCmdDecodeVideoKHR command to execute a query for each video decode operation issued by the command.
• In the pNext chain of the pEncodeInfo parameter of the vkCmdEncodeVideoKHR command to execute a query for each video encode operation issued by the command.
