VkVideoEncodeH264SessionParametersGetInfoKHR

The VkVideoEncodeH264SessionParametersGetInfoKHR structure is defined as:

typedef struct VkVideoEncodeH264SessionParametersGetInfoKHR {
    VkStructureType sType;
    const void* pNext;
    VkBool32 writeStdSPS;
    VkBool32 writeStdPPS;
    uint32_t stdSPSId;
    uint32_t stdPPSId;
} VkVideoEncodeH264SessionParametersGetInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• writeStdSPS indicates whether the encoded H.264 sequence parameter set identified by stdSPSId is requested to be retrieved.
• writeStdPPS indicates whether the encoded H.264 picture parameter set identified by the pair constructed from stdSPSId and stdPPSId is requested to be retrieved.
• stdSPSId specifies the H.264 sequence parameter set ID used to identify the retrieved H.264 sequence and/or picture parameter set(s).
• stdPPSId specifies the H.264 picture parameter set ID used to identify the retrieved H.264 picture parameter set when writeStdPPS is VK_TRUE.

When this structure is specified in the pNext chain of the VkVideoEncodeSessionParametersGetInfoKHR structure passed to vkGetEncodedVideoSessionParametersKHR, the command will write encoded parameter data to the output buffer in the following order:

1. The H.264 sequence parameter set identified by stdSPSId, if writeStdSPS is VK_TRUE.
2. The H.264 picture parameter set identified by the pair constructed from stdSPSId and stdPPSId, if writeStdPPS is VK_TRUE.
