C Specification

Bits which may be set in VkVideoEncodeH265CapabilitiesEXT::transformBlockSizes, indicating the transform block sizes supported by the implementation, are:

// Provided by VK_EXT_video_encode_h265
typedef enum VkVideoEncodeH265TransformBlockSizeFlagBitsEXT {
    VK_VIDEO_ENCODE_H265_TRANSFORM_BLOCK_SIZE_4_BIT_EXT = 0x00000001,
    VK_VIDEO_ENCODE_H265_TRANSFORM_BLOCK_SIZE_8_BIT_EXT = 0x00000002,
    VK_VIDEO_ENCODE_H265_TRANSFORM_BLOCK_SIZE_16_BIT_EXT = 0x00000004,
    VK_VIDEO_ENCODE_H265_TRANSFORM_BLOCK_SIZE_32_BIT_EXT = 0x00000008,
} VkVideoEncodeH265TransformBlockSizeFlagBitsEXT;

Description

  • VK_VIDEO_ENCODE_H265_TRANSFORM_BLOCK_SIZE_4_BIT_EXT specifies that a transform block size of 4x4 is supported.

  • VK_VIDEO_ENCODE_H265_TRANSFORM_BLOCK_SIZE_8_BIT_EXT specifies that a transform block size of 8x8 is supported.

  • VK_VIDEO_ENCODE_H265_TRANSFORM_BLOCK_SIZE_16_BIT_EXT specifies that a transform block size of 16x16 is supported.

  • VK_VIDEO_ENCODE_H265_TRANSFORM_BLOCK_SIZE_32_BIT_EXT specifies that a transform block size of 32x32 is supported.
