Struct H264SliceHeader 

pub struct H264SliceHeader {
    pub first_mb_in_slice: u32,
    pub slice_type: u8,
    pub pic_parameter_set_id: u8,
    pub frame_num: u32,
    pub field_pic_flag: bool,
    pub bottom_field_flag: bool,
    pub idr_pic_id: Option<u32>,
    pub pic_order_cnt_lsb: u32,
}

Minimal slice header (7.3.3 + 7.4.3). Only the fields needed to (a) confirm we have an IDR access unit and (b) populate the HW backends’ picture-info structs.

Fields

first_mb_in_slice: u32

slice_type: u8

slice_type value as emitted; not modulo-5. 0..9.

pic_parameter_set_id: u8

frame_num: u32

field_pic_flag: bool

bottom_field_flag: bool

idr_pic_id: Option<u32>

Present only when this is an IDR slice (NAL type 5).

pic_order_cnt_lsb: u32

Implementations

impl H264SliceHeader

pub fn is_i_slice(&self) -> bool

True if slice_type % 5 == 2 (per 7.4.3 — slice_type values 2 and 7 are I-slices).
