Loading… please wait.

## C Specification

Bits which may be set in VkVideoEncodeH265CapabilitiesKHR::`ctbSizes`, indicating the CTB sizes supported by the implementation, are:

    // Provided by VK_KHR_video_encode_h265
    typedef enum VkVideoEncodeH265CtbSizeFlagBitsKHR {
        VK_VIDEO_ENCODE_H265_CTB_SIZE_16_BIT_KHR = 0x00000001,
        VK_VIDEO_ENCODE_H265_CTB_SIZE_32_BIT_KHR = 0x00000002,
        VK_VIDEO_ENCODE_H265_CTB_SIZE_64_BIT_KHR = 0x00000004,
    } VkVideoEncodeH265CtbSizeFlagBitsKHR;

## Description

- VK_VIDEO_ENCODE_H265_CTB_SIZE_16_BIT_KHR specifies that a CTB size of 16x16 is supported.

- VK_VIDEO_ENCODE_H265_CTB_SIZE_32_BIT_KHR specifies that a CTB size of 32x32 is supported.

- VK_VIDEO_ENCODE_H265_CTB_SIZE_64_BIT_KHR specifies that a CTB size of 64x64 is supported.
