pub struct VorbisConfig {
    pub channels: u8,
    pub sample_rate: u32,
    pub bitrate_maximum: i32,
    pub bitrate_nominal: i32,
    pub bitrate_minimum: i32,

    pub identification_header: Vec<u8>,
    pub comment_header: Vec<u8>,

    /* private fields */
}

The three Vorbis I header packets and what zvidlib reads from them.

Fields

channels: u8

sample_rate: u32

bitrate_maximum: i32

The identification header’s maximum, nominal and minimum bit rates, in bits a second; zero where the stream does not say.

bitrate_nominal: i32

bitrate_minimum: i32

block_sizes: (u16, u16)

The short and long block sizes, in samples.

identification_header: Vec<u8>

comment_header: Vec<u8>

setup_header: Vec<u8>

Implementations

impl VorbisConfig

pub fn from_headers( identification_header: Vec<u8>, comment_header: Vec<u8>, setup_header: Vec<u8>, ) -> Result<VorbisConfig, Error>

Validates and parses the three header packets.

pub fn from_codec_private(codec_private: &[u8]) -> Result<VorbisConfig, Error>

Parses the three header packets Xiph-laced, the form Matroska and WebM CodecPrivate use: a byte holding the packet count less one (two), the first two packets’ sizes as runs of 255 ending in a smaller byte, then the packets.

pub fn to_codec_private(&self) -> Vec<u8>

Writes the three header packets Xiph-laced, as Matroska and WebM CodecPrivate and a WebCodecs decoder description take them.

pub fn packet_block_size(&self, packet: &[u8]) -> Result<u16, Error>

The block size an audio packet codes, read from its mode number.

pub fn encoded_samples( &self, packets: Vec<Vec<u8>>, ) -> Result<Vec<EncodedAudioSample>, Error>

Assigns each audio packet, in stream order, the interval of decoded samples it produces: none for the first, and for every later one a quarter of its block size plus a quarter of the previous packet’s.
