C Specification

Bits which can be set in VkVideoCodingControlInfoKHR::flags, specifying the video coding control parameters to be modified, are:

// Provided by VK_KHR_video_queue
typedef enum VkVideoCodingControlFlagBitsKHR {
    VK_VIDEO_CODING_CONTROL_RESET_BIT_KHR = 0x00000001,
  // Provided by VK_KHR_video_encode_queue
    VK_VIDEO_CODING_CONTROL_ENCODE_RATE_CONTROL_BIT_KHR = 0x00000002,
  // Provided by VK_KHR_video_encode_queue
    VK_VIDEO_CODING_CONTROL_ENCODE_QUALITY_LEVEL_BIT_KHR = 0x00000004,
} VkVideoCodingControlFlagBitsKHR;

Description

  • VK_VIDEO_CODING_CONTROL_RESET_BIT_KHR indicates a request for the bound video session to be reset before other coding control parameters are applied.

  • VK_VIDEO_CODING_CONTROL_ENCODE_RATE_CONTROL_BIT_KHR indicates that the coding control parameters include video encode rate control parameters (see VkVideoEncodeRateControlInfoKHR).

  • VK_VIDEO_CODING_CONTROL_ENCODE_QUALITY_LEVEL_BIT_KHR indicates that the coding control parameters include video encode quality level parameters (see VkVideoEncodeQualityLevelInfoKHR).
