Members

Valid Usage
  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-spsStdCount-04837
    The values of spsStdCount and ppsStdCount must be less than or equal to the values of maxSpsStdCount and maxPpsStdCount, respectively

  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-maxSpsStdCount-04838
    When the maxSpsStdCount number of parameters of type StdVideoH264SequenceParameterSet in the Video Session Parameters object is reached, no additional parameters of that type can be added to the object. VK_ERROR_TOO_MANY_OBJECTS will be returned if an attempt is made to add additional data to this object at this point

  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-maxPpsStdCount-04839
    When the maxPpsStdCount number of parameters of type StdVideoH264PictureParameterSet in the Video Session Parameters object is reached, no additional parameters of that type can be added to the object. VK_ERROR_TOO_MANY_OBJECTS will be returned if an attempt is made to add additional data to this object at this point

  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-None-04840
    Each entry to be added must have a unique, to the rest of the parameter array entries and the existing parameters in the Video Session Parameters Object that is being updated, SPS-PPS IDs

  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-None-04841
    Parameter entries that already exist in Video Session Parameters object with a particular SPS-PPS IDs cannot be replaced nor updated

  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-None-04842
    When creating a new object using a Video Session Parameters as a template, the array’s parameters with the same SPS-PPS IDs as the ones from the template take precedence

  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-None-04843
    SPS/PPS parameters must comply with the limits specified in VkVideoSessionCreateInfoKHR during Video Session creation

Description

Valid Usage (Implicit)
  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H264_SESSION_PARAMETERS_ADD_INFO_EXT

  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-pSpsStd-parameter
    If pSpsStd is not NULL, pSpsStd must be a valid pointer to an array of spsStdCount StdVideoH264SequenceParameterSet values

  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-pPpsStd-parameter
    If pPpsStd is not NULL, pPpsStd must be a valid pointer to an array of ppsStdCount StdVideoH264PictureParameterSet values

  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-spsStdCount-arraylength
    spsStdCount must be greater than 0

  • VUID-VkVideoEncodeH264SessionParametersAddInfoEXT-ppsStdCount-arraylength
    ppsStdCount must be greater than 0
