Struct MediaInfo 

#[non_exhaustive]
pub struct MediaInfo {
    pub channels: Option<u16>,
    pub codec: Option<AudioCodec>,
    pub container: Option<ContainerFormat>,
    pub sample_rate: Option<u32>,
    pub variant_index: Option<u32>,
}

Media format information.

This information can be derived from:

• HLS playlist CODECS attribute (e.g., mp4a.40.2)
• File extension
• HTTP Content-Type header
• Container metadata

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

channels: Option<u16>

Number of audio channels

codec: Option<AudioCodec>

Audio codec

container: Option<ContainerFormat>

Container format (fMP4, MPEG-TS, etc.)

sample_rate: Option<u32>

Sample rate in Hz

variant_index: Option<u32>

Variant index (for ABR streams). Different variants have different init segments (ftyp/moov), so decoder must be recreated when variant changes.

Implementations

impl MediaInfo

pub fn builder() -> MediaInfoBuilder

Create an instance of MediaInfo using the builder syntax

impl MediaInfo

pub fn new( codec: Option<AudioCodec>, container: Option<ContainerFormat>, ) -> Self

Create MediaInfo with optional codec and container.

pub fn parse_mime(mime: &str) -> Option<Self>

Parse codec and container from an HTTP Content-Type value.

Distinct from AudioCodec::parse_mime, which returns the codec only. Standalone HTTP file sources can lose container information if the caller drops it on the floor; downstream Apple/Android dispatch needs both codec and container to pick a backend.

Trait Implementations

impl Clone for MediaInfo

fn clone(&self) -> MediaInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MediaInfo

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

Formats the value using the given formatter.

impl Default for MediaInfo

fn default() -> MediaInfo

Returns the “default value” for a type.

impl From<AudioCodec> for MediaInfo

Build MediaInfo from a codec alone, filling the container when it is implied by the codec for standalone (non-HLS) sources. AAC and Adpcm have ambiguous containers and leave container = None.

fn from(codec: AudioCodec) -> Self

Converts to this type from the input type.

impl PartialEq for MediaInfo

fn eq(&self, other: &MediaInfo) -> 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.
