```rust use std::fs::File; use smmotionphoto::SmMotion;
// open file let photofile = File::open("photo.jpg").unwrap(); let mut sm = SmMotion::with(&photofile).unwrap(); println!("JPEG file contains video? {:?}", sm.hasvideo()); let mut videofile = File::create("video.mp4").unwrap(); // dump mp4 from jpeg sm.dumpvideofile(&mut videofile).unwrap(); // get video duration (no dump needed) println!("{:?}", sm.getvideofileduration()); // get MP4 file context println!("{:?}", sm.findvideocontext()); // You can also save index and use it afterwards let mut smcached = SmMotion::withprecalculated(&photofile, 3366251).unwrap(); println!("{:?}", smcached.getvideofile_duration()); ```
