Module format 

Container format support for muxing and demuxing.

This module provides functionality for reading (demuxing) and writing (muxing) multimedia container formats. It wraps FFmpeg’s libavformat library with safe Rust interfaces.

Main Components

• Context - Format context managing streams and container metadata
• stream - Individual media streams within a container
• chapter - Chapter/bookmark support for seekable formats
• format - Container format information and discovery

Common Operations

Opening Files for Reading

Use input() to open a media file for reading:

let mut input = ffmpeg::format::input(&"video.mp4")?;

// Find best video stream
let stream = input.streams().best(Type::Video).unwrap();
let decoder = stream.codec().decoder().video()?;

Opening Files for Writing

Use output() to create a new media file:

let mut output = ffmpeg::format::output(&"output.mp4")?;

// Add video stream
let mut stream = output.add_stream(encoder)?;
stream.set_parameters(&encoder);

output.write_header()?;
// ... write packets ...
output.write_trailer()?;
