Struct chd::codecs::RawFlacCodec

pub struct RawFlacCodec { /* private fields */ }

Available on codec_api only.

Raw FLAC (flac) decompression codec.

Format details

Raw FLAC expects the first byte as either ‘L’ (0x4C) or ‘B’ (0x42) to indicate the endianness of the output data, followed by the compressed FLAC data.

FLAC compressed audio data is assumed to be 2-channel 16-bit signed integer PCM. The audio data is decompressed in interleaved format, with the left channel first, then the right channel for each sample, for 32 bits each sample.

Buffer Restrictions

Each compressed FLAC hunk decompresses to a hunk-sized chunk. The input buffer must contain enough samples to fill the hunk-sized output buffer.

Trait Implementations

impl CodecImplementation for RawFlacCodec

fn new(hunk_bytes: u32) -> Result<Self>

Creates a new instance of this codec for the provided hunk size.

fn decompress( &mut self, input: &[u8], output: &mut [u8] ) -> Result<DecompressResult>

Decompress compressed bytes from the input buffer into the output buffer.

impl CompressionCodecType for RawFlacCodec

fn codec_type(&self) -> CodecType

where Self: Sized,

Returns the known CodecType that this codec implements.
