Struct CodecParameters 

pub struct CodecParameters {
    pub codec_id: CodecId,
    pub media_type: MediaType,
    pub sample_rate: Option<u32>,
    pub channels: Option<u16>,
    pub sample_format: Option<SampleFormat>,
    pub width: Option<u32>,
    pub height: Option<u32>,
    pub pixel_format: Option<PixelFormat>,
    pub frame_rate: Option<Rational>,
    pub extradata: Vec<u8>,
    pub bit_rate: Option<u64>,
}

Codec-level parameters shared between demuxer/muxer and en/decoder.

Fields

codec_id: CodecId

media_type: MediaType

sample_rate: Option<u32>

channels: Option<u16>

sample_format: Option<SampleFormat>

width: Option<u32>

height: Option<u32>

pixel_format: Option<PixelFormat>

frame_rate: Option<Rational>

extradata: Vec<u8>

Per-codec setup bytes (e.g., SPS/PPS, OpusHead). Format defined by codec.

bit_rate: Option<u64>

Implementations

impl CodecParameters

pub fn audio(codec_id: CodecId) -> Self

pub fn matches_core(&self, other: &CodecParameters) -> bool

True when self and other have the same codec_id and core format parameters (sample_rate/channels/sample_format for audio, width/height/pixel_format for video). Extradata and bitrate differences are tolerated — many containers rewrite extradata losslessly during a copy operation.

pub fn video(codec_id: CodecId) -> Self

Trait Implementations

impl Clone for CodecParameters

fn clone(&self) -> CodecParameters

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CodecParameters

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
