Complete description of a codec as stored in the registry.

Fields

codec_id: CodecId

Canonical CodecId variant.

name: String

Short lowercase name used for string-based lookup (e.g. "av1").

long_name: Option<String>

Optional human-readable long name (e.g. "AOMedia Video 1").

fourccs: Vec<Fourcc>

All FOURCC codes associated with this codec.

can_encode: bool

Whether this codec entry supports encoding.

can_decode: bool

Whether this codec entry supports decoding.

is_lossless: bool

Whether lossless mode is available.

profiles: Vec<CodecProfile>

Named profiles supported by this codec.

max_bit_depth: u8

Maximum bit depth (e.g. 8, 10, 12).

Implementations

impl CodecDescriptor

pub fn new(codec_id: CodecId) -> Self

Create a minimal descriptor from a CodecId.

pub fn with_long_name(self, s: impl Into<String>) -> Self

Builder: set the long name.

pub fn with_fourcc(self, fourcc: Fourcc) -> Self

Builder: add a FOURCC.

pub fn with_direction(self, dir: CodecDirection) -> Self

Builder: set encode/decode direction.

pub fn with_lossless(self, lossless: bool) -> Self

Builder: override lossless flag (normally derived from CodecId::is_lossless).

pub fn with_profile(self, profile: CodecProfile) -> Self

Builder: add a profile entry.

pub fn with_max_bit_depth(self, depth: u8) -> Self

Builder: set maximum bit depth.

pub fn has_fourcc(&self, fourcc: &Fourcc) -> bool

Returns true if this descriptor supports a given FOURCC.

pub fn profile_by_name(&self, name: &str) -> Option<&CodecProfile>

Look up a profile by name (case-insensitive).

pub fn profile_by_id(&self, id: u32) -> Option<&CodecProfile>

Look up a profile by numeric id.
