Implementations§

Source§

impl Mp3Decoder

Source

pub fn new() -> Self

Create a new MP3 decoder

Source

pub fn find_sync(data: &[u8], start: usize) -> Option<usize>

Find the next MP3 frame sync in the data

Scans for the 0xFFE0 sync word. Returns the byte offset of the sync.

Source

pub fn decode_frame(&mut self, data: &[u8]) -> CodecResult<usize>

Decode a single MP3 frame

Returns the number of bytes consumed from the input.

Source

pub fn decode_all(&mut self, data: &[u8]) -> CodecResult<(u32, u8, Vec<i16>)>

Decode an entire MP3 file to PCM

Returns (sample_rate, channels, pcm_samples).

Source

pub fn output(&self) -> &[i16]

Get the decoded PCM output from the last frame

Source

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

Get the sample rate from the last decoded frame

Source

pub fn channels(&self) -> Option<u8>

Get the number of channels from the last decoded frame
