Example

```rust use std::fs::File; use std::io::{BufReader}; use mp4::{Result};

fn main() -> Result<()> { let f = File::open("tests/samples/minimal.mp4").unwrap(); let size = f.metadata()?.len(); let reader = BufReader::new(f);

let mp4 = mp4::Mp4Reader::read_header(reader, size)?;

// Print boxes.
println!("major brand: {}", mp4.ftyp.major_brand);
println!("timescale: {}", mp4.moov.mvhd.timescale);

// Use available methods.
println!("size: {}", mp4.size());

let mut compatible_brands = String::new();
for brand in mp4.compatible_brands().iter() {
    compatible_brands.push_str(&brand.to_string());
    compatible_brands.push_str(",");
}
println!("compatible brands: {}", compatible_brands);
println!("duration: {:?}", mp4.duration());

// Track info.
for track in mp4.tracks().iter() {
    println!(
        "track: #{}({}) {} : {}",
        track.track_id(),
        track.language(),
        track.track_type()?,
        track.box_type()?,
    );
}
Ok(())

} ```
