1//! Elements that produce buffers.
2//!
3//! Three shapes live here. Readers pull from something that already exists —
4//! a container, an RTSP stream, a capture device, or the application itself
5//! through [`AppSource`]. Generators synthesize
6//! ([`TestVideoSource`], [`TestAudioSource`]). And fan-in elements
7//! ([`AudioMixer`] and the video compositors) are sources with inputs: they
8//! accept buffers from several upstream branches and emit one combined stream
9//! on their own schedule.
10//!
11//! [`Pipeline::new`](crate::pipeline::Pipeline::new) builds the common
12//! single-source case. [`PipelineBuilder`](crate::pipeline::PipelineBuilder)
13//! can register one or more of these in the same pipeline; each one's
14//! [`SourceElement::run`](crate::element::SourceElement::run) loop drives its
15//! own branches on a separate background thread.
