Fields

frame_type: u8

frame_type — KEY_FRAME or INTRA_ONLY_FRAME in this decoder.

show_frame: bool

Whether the frame is shown.

showable_frame: bool

Whether the frame is later showable.

error_resilient_mode: bool

Whether error-resilient mode is set.

disable_cdf_update: bool

Whether CDF updates are disabled for the frame.

allow_screen_content_tools: bool

Whether screen-content tools are allowed.

frame_width: u32

Coded frame width, after any super-resolution downscale.

frame_height: u32

Implementations

impl FrameHeader

pub fn parse( r: &mut BitReader<'_>, seq: &SequenceHeader, temporal_id: u8, spatial_id: u8, ) -> Result<Self>

Parse an intra frame header, given the governing sequence header and the OBU’s temporal/spatial layer ids.

Trait Implementations

impl Clone for FrameHeader

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameHeader

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

Formats the value using the given formatter.
