Module keyframe 

Keyframe and Group of Pictures analysis.

This module provides KeyFrameMetadata and GroupOfPicturesInfo for inspecting the keyframe distribution and Group of Pictures structure of a video stream without full-frame decoding.

Example

use unbundle::{MediaFile, UnbundleError};

let mut unbundler = MediaFile::open("input.mp4")?;
let group_of_pictures = unbundler.video().analyze_group_of_pictures()?;
println!("Total keyframes: {}", group_of_pictures.keyframes.len());
println!("Average Group of Pictures size: {:.1}", group_of_pictures.average_group_of_pictures_size);
println!("Max Group of Pictures size: {}", group_of_pictures.max_group_of_pictures_size);

Structs

Summary of the Group of Pictures structure.
