Struct SliceHeader 

pub struct SliceHeader {
    pub slice_type: SliceType,
    pub frame_num: u16,
    pub pic_parameter_set_id: u8,
    pub field_pic_flag: bool,
    pub bottom_field_flag: bool,
    pub idr_pic_id: Option<u16>,
    pub nal_ref_idc: u8,
}

Parsed fields from a slice header.

Fields

slice_type: SliceType

Slice type.

frame_num: u16

frame_num syntax element (wraps at MaxFrameNum).

pic_parameter_set_id: u8

PPS id referenced by this slice.

field_pic_flag: bool

field_pic_flag: true when this slice belongs to a field (not a frame).

bottom_field_flag: bool

bottom_field_flag: relevant only when field_pic_flag is true.

idr_pic_id: Option<u16>

IDR picture id (only meaningful for IDR slices).

nal_ref_idc: u8

nal_ref_idc from the enclosing NAL unit (0 = non-reference).

Implementations

impl SliceHeader

pub fn is_reference(&self) -> bool

Returns true if this slice is a reference slice (nal_ref_idc > 0).

pub fn is_idr(&self) -> bool

Returns true if this slice is an IDR slice.

pub fn is_keyframe(&self) -> bool

Returns true if this is a key-frame (IDR or I-slice that is reference).

Trait Implementations

impl Clone for SliceHeader

fn clone(&self) -> SliceHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SliceHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
