Source
pub struct BufferModel { /* private fields */ }
Expand description

Buffer model for HRD (Hypothetical Reference Decoder) compliance.

Implements the CPB (Coded Picture Buffer) model as defined in video coding standards for streaming compliance.

Implementations§

Source§

impl BufferModel

Source

pub fn new( cpb_size: u64, bitrate: u64, framerate: f64, initial_delay: f64, ) -> Self

Create a new buffer model.

Source

pub fn fill_for_frame(&mut self)

Source

pub fn remove_frame_bits(&mut self, bits: u64)

Remove bits for an encoded frame.

Source

pub fn encode_frame(&mut self, bits: u64)

Source

pub fn fullness(&self) -> f32

Get buffer fullness as fraction.

Source

pub fn level(&self) -> u64
