ff_filter/graph/composition/mod.rs
1//! Multi-track video composition and audio mixing.
2//!
3//! This module provides [`MultiTrackComposer`] for compositing multiple video
4//! layers onto a solid-colour canvas, and [`MultiTrackAudioMixer`] for mixing
5//! multiple audio tracks into a single output stream.
6//!
7//! Both types produce source-only `FilterGraph` instances — call
8//! `FilterGraph::pull_video` or `FilterGraph::pull_audio` in a loop to
9//! extract output frames.
