Fields

reader: IMFSourceReader

stream: u32

duration: f64

rate: u32

Format the reader delivers (48000/2 when MF converts for us).

ch: u32

fifo: Vec<f32>

Decoded stereo @ SAMPLE_RATE; fifo_pos = output frame index of fifo[0] (valid when located).

fifo_pos: i64

located: bool

eof_at: Option<i64>

Output frame index where the data ends (known once EOF was hit).

origin: i64

Output frame index of the first sample = content t=0 (see MfVideo::origin).

mp4: bool

rs: Resamp

tmp: Vec<f32>

Implementations

impl MfAudio

fn fifo_end(&self) -> i64

fn seek(&mut self, f0: i64) -> bool

fn mark_eof(&mut self, f0: i64)

fn decode_more(&mut self, f0: i64) -> bool

Decode one more sample into the FIFO. False at EOF / error.

Trait Implementations

impl AudioSource for MfAudio

fn duration(&self) -> f64

fn read_at(&mut self, t: f64, out: &mut [f32])

Fill out (interleaved stereo f32 @ SAMPLE_RATE, frames = out.len()/2) starting at source time t. Zero-fill past the end. Must be cheap for sequential calls (t advancing by exactly the previous block).
