MediaKind

Enum MediaKind 

Source
pub enum MediaKind {
    Video,
    Audio,
    Subtitle,
    Data,
    Attachment,
    Unknown,
}
Expand description

What a track is, folded from AVCodecParameters.codec_type read as the integer it is on the wire.

The dependency-API half of this crate’s open-C-enum discipline. ffmpeg_next::codec::Parameters::medium() materialises an AVMediaType out of FFmpeg memory to answer the same question, and a value outside this build’s discriminant set is undefined behaviour the moment it exists — before any match on it can run. That the set is small and has been stable for years is a reason it has not bitten, not a reason it cannot.

So the read is raw and the fold is total: anything this build does not name becomes Unknown, which the callers already had to handle.

Variants§

§

Unknown

Anything this build of FFmpeg does not name, AVMEDIA_TYPE_UNKNOWN included.
