Function av_metrics::video::ciede::calculate_video_ciede

pub fn calculate_video_ciede<D: Decoder, F: Fn(usize) + Send>(
    decoder1: &mut D,
    decoder2: &mut D,
    frame_limit: Option<usize>,
    progress_callback: F
) -> Result<f64, Box<dyn Error>>

Calculate the CIEDE2000 metric between two video clips. Higher is better.

This will return at the end of the shorter of the two clips, comparing any frames up to that point.

Optionally, frame_limit can be set to only compare the first frame_limit frames in each video.
