Crate mp4

mp4 is a Rust library to read and write ISO-MP4 files.

This package contains MPEG-4 specifications defined in parts:

• ISO/IEC 14496-12 - ISO Base Media File Format (QuickTime, MPEG-4, etc)
• ISO/IEC 14496-14 - MP4 file format
• ISO/IEC 14496-17 - Streaming text format

See: mp4box for supported MP4 atoms.

Example

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(())
}
