Holds every container format known to a running engine.

Implementations

impl FormatRegistry

pub fn new() -> FormatRegistry

pub fn register(&mut self, format: Format)

pub fn by_name(&self, name: &str) -> Option<&Format>

pub fn by_extension(&self, ext: &str) -> Option<&Format>

Find a format whose extension list contains ext (case-insensitive, no leading dot). The cheap “guess by filename” path; probe inspects content instead.

pub fn probe(&self, data: &[u8]) -> Option<&Format>

Identify a format by sniffing a byte prefix: the registered format whose probe returns the highest positive score wins. Returns None if nothing recognizes the data.

pub fn open_demuxer(&self, name: &str, input: Input) -> Result<Box<dyn Demuxer>>

Open a demuxer for the format named name.

pub fn open_muxer(&self, name: &str, output: Output) -> Result<Box<dyn Muxer>>

Open a muxer for the format named name.

pub fn iter(&self) -> impl Iterator<Item = &Format>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
