Struct CodecParams 

pub struct CodecParams {
    pub codec_id: CodecId,
    pub inner: CodecParamsInner,
    pub stream_index: Option<u32>,
    pub language: Option<String>,
}

Codec-agnostic parameter descriptor for a single elementary stream.

Combines a CodecId with either VideoParams, AudioParams, or a bare Data marker for subtitle/attachment streams.

Fields

codec_id: CodecId

The codec used to encode this stream.

inner: CodecParamsInner

Type-specific parameters.

stream_index: Option<u32>

Optional stream index within the container (0-based).

language: Option<String>

Optional stream language tag (BCP-47, e.g. "en", "ja").

Implementations

impl CodecParams

pub fn video(codec_id: CodecId, params: VideoParams) -> Self

Creates a CodecParams for a video stream.

pub fn audio(codec_id: CodecId, params: AudioParams) -> Self

Creates a CodecParams for an audio stream.

pub fn data(codec_id: CodecId) -> Self

Creates a CodecParams for a data/subtitle stream.

pub fn is_video(&self) -> bool

Returns true if these are video codec parameters.

pub fn is_audio(&self) -> bool

Returns true if these are audio codec parameters.

pub fn video_params(&self) -> Option<&VideoParams>

Returns a reference to the VideoParams, if present.

pub fn audio_params(&self) -> Option<&AudioParams>

Returns a reference to the AudioParams, if present.

pub fn with_stream_index(self, index: u32) -> Self

Builder-style setter for stream index.

pub fn with_language(self, lang: impl Into<String>) -> Self

Builder-style setter for language tag.

Trait Implementations

impl Clone for CodecParams

fn clone(&self) -> CodecParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CodecParams

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

Formats the value using the given formatter.

impl PartialEq for CodecParams

fn eq(&self, other: &CodecParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
