pub struct Context<D: Decoder> { /* private fields */ }

Expand description

Auxiliary structure to encapsulate a decoder object and its additional data.

Implementations

source

impl<D: Decoder> Context<D>

source

pub fn by_name<T: Descriptor<OutputDecoder = D> + ?Sized>(
codecs: &Codecs<T>,
name: &str
) -> Option<Self>

Retrieves a codec descriptor from a codec list through its name, creates the relative decoder, and encapsulates it into a new Context.

source

pub fn set_extradata(&mut self, extra: &[u8])

Saves the extra data contained in a codec.

source

pub fn send_packet(&mut self, pkt: &Packet) -> Result<()>

Sends to the decoder a packet to be decoded.

source

pub fn receive_frame(&mut self) -> Result<ArcFrame>

Returns a decoded frame.

source

pub fn configure(&mut self) -> Result<()>

Configures the decoder.

source

pub fn flush(&mut self) -> Result<()>

Tells decoder to clear its internal state.

source

pub fn decoder(&self) -> &D

Returns the underlying decoder.
