C Specification

The H.264 video decode picture layout flags are defined with the following enum:

// Provided by VK_EXT_video_decode_h264
typedef enum VkVideoDecodeH264PictureLayoutFlagBitsEXT {
    VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_PROGRESSIVE_EXT = 0,
    VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_INTERLACED_INTERLEAVED_LINES_BIT_EXT = 0x00000001,
    VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_INTERLACED_SEPARATE_PLANES_BIT_EXT = 0x00000002,
} VkVideoDecodeH264PictureLayoutFlagBitsEXT;

Description

  • VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_PROGRESSIVE_EXT specifies support for progressive content. This flag has the value 0.

  • VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_INTERLACED_INTERLEAVED_LINES_BIT_EXT specifies support for or use of a picture layout for interlaced content where all lines belonging to the first field are decoded to the even-numbered lines within the picture resource, and all lines belonging to the second field are decoded to the odd-numbered lines within the picture resource.

  • VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_INTERLACED_SEPARATE_PLANES_BIT_EXT specifies support for or use of a picture layout for interlaced content where all lines belonging to the first field are grouped together in a single plane, followed by another plane containing all lines belonging to the second field.
