Trait av_metrics::video::Decoder

pub trait Decoder: Send + Sync {
    fn read_video_frame<T: Pixel>(&mut self) -> Result<FrameInfo<T>, ()>;
    fn read_specific_frame<T: Pixel>(
        &mut self, 
        frame_number: usize
    ) -> Result<FrameInfo<T>, ()>;
    fn get_bit_depth(&self) -> usize;
    fn get_video_details(&self) -> VideoDetails;
}

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) -> Result<FrameInfo<T>, ()>

Read the next frame from the input video.

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

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

Read a specific frame from the input video

Expected to return Err if the frame is not found.

fn get_bit_depth(&self) -> usize

Get the bit depth of the video.

fn get_video_details(&self) -> VideoDetails

Get the Video Details
