1//! Extension providers: frames of formats the host's video and image
2//! decoders do not read, supplied through one contract.
3//!
4//! A provider probes bytes (never a file name) and opens a source that
5//! answers frames by source time. The host registers the providers its build
6//! includes, in priority order, and feeds their frames to the engine like any
7//! other source's; the engine and the renderer know nothing of them. Each
8//! format is a cargo feature: a build without one still renders everything
9//! else, and reports that format's sources as unsupported.
