Trait afi::Decoder

pub trait Decoder<T>where
    Self: Sized,{
    fn new(data: T, colors: ColorChannels) -> Option<Self>;
    fn run(
        &mut self,
        audio: &mut Option<Audio>,
        video: &mut Option<Video>
    ) -> Option<bool>;
    fn get(&self) -> Index;
    fn set(&mut self, index: Index);
}

A trait for implementing decoding audio, video or both.

Required Methods

fn new(data: T, colors: ColorChannels) -> Option<Self>

Create a new decoder for this format. None is returned when the decoder can’t handle data’s format: try a different decoder.

fn run(
    &mut self,
    audio: &mut Option<Audio>,
    video: &mut Option<Video>
) -> Option<bool>

Decode a frame. None is returned if the file is corrupt, Some(true) if it succeeded, and Some(false) if it can’t add anymore frames because the input file ended. audio and video should initially be set to None.

fn get(&self) -> Index

Get the frame number (24 frames per second).

fn set(&mut self, index: Index)

Set the frame number to seek forward or backwards.
