VkVideoDecodeH264PictureLayoutFlagBitsKHR

The H.264 video decode picture layout flags are defined as follows:

typedef enum VkVideoDecodeH264PictureLayoutFlagBitsKHR {
    VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_PROGRESSIVE_KHR = 0,
    VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_INTERLACED_INTERLEAVED_LINES_BIT_KHR = 0x00000001,
    VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_INTERLACED_SEPARATE_PLANES_BIT_KHR = 0x00000002,
} VkVideoDecodeH264PictureLayoutFlagBitsKHR;

pub struct VideoDecodeH264PictureLayoutFlagBitsKHR(u32);
impl VideoDecodeH264PictureLayoutFlagBitsKHR {
    pub const PROGRESSIVE: Self = 0;
    pub const INTERLACED_INTERLEAVED_LINES: Self = 0x00000001;
    pub const INTERLACED_SEPARATE_PLANES: Self = 0x00000002;
}

• VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_PROGRESSIVE_KHR specifies support for progressive content. This flag has the value 0.
• VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_INTERLACED_INTERLEAVED_LINES_BIT_KHR specifies support for or use of a picture layout for interlaced content where all lines belonging to the top field are decoded to the even-numbered lines within the picture resource, and all lines belonging to the bottom field are decoded to the odd-numbered lines within the picture resource.
• VK_VIDEO_DECODE_H264_PICTURE_LAYOUT_INTERLACED_SEPARATE_PLANES_BIT_KHR specifies support for or use of a picture layout for interlaced content where all lines belonging to a field are grouped together in a single image subregion, and the two fields comprising the frame can be stored in separate image subregions of the same image subresource or in separate image subresources.
