Struct Decoder 

pub struct Decoder { /* private fields */ }

A WMA v2 decoder for one stream. Give it the packets in order with decode_packet, then call flush once at the end.

Implementations

impl Decoder

pub fn new(p: &Params) -> Result<Self>

A decoder for a stream with these parameters. It fails when the format tag is not WMA v2 or the parameters are not supported.

pub fn channels(&self) -> usize

The number of channels.

pub fn sample_rate(&self) -> u32

The sample rate, in samples per second.

pub fn delay(&self) -> usize

Codec delay in samples per channel: the first two frames only prime the overlap and are not output.

pub fn frame_len(&self) -> usize

Samples per channel produced by each frame.

pub fn decode_packet(&mut self, packet: &[u8], out: &mut Vec<f32>) -> Result<()>

Decode one packet (block_align bytes), appending interleaved samples in [-1, 1) to out. On error nothing is appended and the bit reservoir is dropped, so the next packet starts cleanly.

pub fn flush(&mut self, out: &mut Vec<f32>)

Emit the final overlap tail (one frame) after the last packet and reset.

pub fn reset(&mut self)

Forget all stream state, e.g. before seeking.
