MP4 Reader and Writer in Rust 🦀
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
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().values() {
println!(
"track: #{}({}) {} : {}",
track.track_id(),
track.language(),
track.track_type()?,
track.box_type()?,
);
}
Ok(())
}
