Struct CabacEncoder 

pub struct CabacEncoder {
    pub contexts: Vec<CabacContext>,
    pub coder: ArithmeticCoder,
    pub bins_encoded: u64,
}

CABAC encoder with multiple context models.

Fields

contexts: Vec<CabacContext>

Context model array (indexed by context ID).

coder: ArithmeticCoder

Underlying arithmetic coder.

bins_encoded: u64

Total bins encoded.

Implementations

impl CabacEncoder

pub fn new(num_contexts: usize) -> Self

Create a CABAC encoder with num_contexts equi-probable contexts.

pub fn encode_bin(&mut self, ctx_id: usize, bin: bool) -> Vec<u8>

Encode a single bin using context ctx_id.

Returns any bytes flushed from the arithmetic coder.

pub fn encode_bypass(&mut self, bin: bool) -> Vec<u8>

Encode a bin in bypass mode (equi-probable, no context update).
