C Specification

Bits which may be set in VkVideoEncodeH265CapabilitiesEXT::ctbSizes, indicating the CTB sizes supported by the implementation, are:

// Provided by VK_EXT_video_encode_h265
typedef enum VkVideoEncodeH265CtbSizeFlagBitsEXT {
    VK_VIDEO_ENCODE_H265_CTB_SIZE_16_BIT_EXT = 0x00000001,
    VK_VIDEO_ENCODE_H265_CTB_SIZE_32_BIT_EXT = 0x00000002,
    VK_VIDEO_ENCODE_H265_CTB_SIZE_64_BIT_EXT = 0x00000004,
} VkVideoEncodeH265CtbSizeFlagBitsEXT;


  • VK_VIDEO_ENCODE_H265_CTB_SIZE_16_BIT_EXT specifies that a CTB size of 16x16 is supported.

  • VK_VIDEO_ENCODE_H265_CTB_SIZE_32_BIT_EXT specifies that a CTB size of 32x32 is supported.

  • VK_VIDEO_ENCODE_H265_CTB_SIZE_64_BIT_EXT specifies that a CTB size of 64x64 is supported.
