Trait av_metrics::video::decode::Decoder

pub trait Decoder: Send {
    // Required methods
    fn read_video_frame<T: Pixel>(&mut self) -> Option<Frame<T>>;
    fn get_bit_depth(&self) -> usize;
    fn get_video_details(&self) -> VideoDetails;

    // Provided method
    fn read_specific_frame<T: Pixel>(
        &mut self,
        frame_number: usize
    ) -> Option<Frame<T>> { ... }
}

A trait for allowing metrics to decode generic video formats.

Currently, y4m decoding support using the y4m crate is built-in to this crate. This trait is extensible so users may implement their own decoders.

Required Methods

fn read_video_frame<T: Pixel>(&mut self) -> Option<Frame<T>>

Read the next frame from the input video.

Expected to return Err if the end of the video is reached.

fn get_bit_depth(&self) -> usize

Get the bit depth of the video.

fn get_video_details(&self) -> VideoDetails

Get the Video Details

Provided Methods

fn read_specific_frame<T: Pixel>( &mut self, frame_number: usize ) -> Option<Frame<T>>

Read a specific frame from the input video

Expected to return Err if the frame is not found.
