VkVideoDecodeH264PictureLayoutFlagBitsEXT - H.264 video decode picture layout flags

Loading… please wait.

## 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.
