Struct Parser

pub struct Parser {
    pub last_frame_header: Option<FrameHeaderObu>,
    pub sequence_header: Option<Rc<SequenceHeaderObu>>,
    /* private fields */
}

Fields

last_frame_header: Option<FrameHeaderObu>

We keep this to implement frame_header_copy() in the specification, and to fill in StreamInfo render_width and render_height.

sequence_header: Option<Rc<SequenceHeaderObu>>

The last SequenceHeaderObu parsed.

Implementations

impl Parser

pub fn read_obu<'a>(&mut self, data: &'a [u8]) -> Result<ObuAction<'a>, String>

Parses one OBU from data, which can be in Annex B or low-overhead format.

None may eventually be returned if the OBU is to be dropped.

pub fn choose_operating_point( &mut self, operating_point: u32, ) -> Result<(), String>

Selects an operating point. Only call this after the Sequence OBU for which the operating point should apply has been parsed.

pub fn parse_frame_header_obu( &mut self, obu: &Obu<'_>, ) -> Result<FrameHeaderObu, String>

pub fn ref_frame_update(&mut self, fh: &FrameHeaderObu) -> Result<(), String>

Implements 7.20. This function should be called right after decoding a frame.

pub fn highest_operating_point(&self) -> Option<u32>

pub fn parse_obu<'a>(&mut self, obu: Obu<'a>) -> Result<ParsedObu<'a>, String>

Fully parse an OBU.

Trait Implementations

impl Clone for Parser

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 Parser

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

Formats the value using the given formatter.

impl Default for Parser

fn default() -> Self

Returns the “default value” for a type.
