Crate rff_format 

rff-format — the container (muxer/demuxer) abstraction layer (FFmpeg’s libavformat core, minus the formats themselves).

A container is the file wrapper (AVI, MP4, Matroska, …) that interleaves one or more elementary streams. This crate defines:

• Stream — the description of one elementary stream inside a container,
• Demuxer — reads a container, exposing streams and Packets,
• Muxer — writes streams + packets back into a container,
• FormatRegistry — what individual format crates register into.

Concrete formats live in their own crates (rff-format-avi, …).

Structs

Format

Static description of a container format and its read/write support.

FormatRegistry

Holds every container format known to a running engine.

Stream

Description of one elementary stream within a container.

Traits

Demuxer

Reads a container format: parses the header into Streams, then yields Packets until the input is exhausted.

Muxer

Writes a container format: declare streams, write packets, finalize.

Type Aliases

DemuxerFactory

Factory opening a demuxer over an input byte source.

Input

A byte source a demuxer reads from. (Box<dyn Read + Send> keeps the trait object-safe and lets inputs be files, network streams, or in-memory buffers.)

MuxerFactory

Factory opening a muxer over an output byte sink.

Output

A byte sink a muxer writes to.

ProbeFn

Content sniffer: scores how strongly a byte prefix looks like this format, 0 (no match) to 100 (certain) — mirrors FFmpeg’s AVInputFormat::read_probe.
