Crate rusty_esp_video 

rusty_esp_video — esp_video / esp_h264 / CameraWebServer remade in Rust: MJPEG and H.264 (rusty_h264 embedded) encode, RTP + MJPEG-over-HTTP packetizers, P4 hardware encoder wrap. Memory safe, no_std core.

This is the facade: it re-exports the no_std core and exposes the chip backends under esp. Depend on this crate; reach into the sub-crates only when you are building a backend.

Part of Janus (Remade With Rust). Plan: docs/plans/rusty_esp_video.md.

Modules

annexb

H.264 Annex-B byte-stream helpers: find NAL units between start codes and split a stream into access units.

encoder

The encoder seam.

esp

Chip backends (esp-hal for Track B, esp-idf for Track A).

esp_core

rusty_esp_core — the shared vocabulary of the Janus ESP family.

mjpeg_http

multipart/x-mixed-replace — the CameraWebServer stream, remade.

mjpeg_reader

The receiving side of crate::mjpeg_http: a streaming parser for a multipart/x-mixed-replace JPEG stream over a caller-owned buffer.

mpegts

An MPEG-2 transport stream mux for H.264 — the container rff -i udp:// and ffmpeg read today, so a device stream can be verified end to end with the tools the house already trusts.

pacer

A frame-rate cap and a byte budget, with honest counters.

packet

The one packet type the media packages share.

policy

Which encoder for which job — the codec policy, as data and one function.

prelude

The names a sketch or firmware wants in scope.

rtp

RTP: the fixed header, payloaders for H.264 (RFC 6184, single NAL unit and FU-A fragmentation) and JPEG (RFC 2435), and the JPEG depayloader that turns RFC 2435 packets back into a JPEG file in a caller buffer.

sink

Where bytes go.

source

Where packets come from.

udp

Raw datagram framing — the Pi-hub UDP recipe, made precise.

Structs

Choice

The codec a chip should emit for a job, and what the host does after.

EncodedSource

An ImageSource feeding a VideoEncoder, with a frame-rate cap.

EncoderConfig

What a firmware asks an encoder for.

MediaPacket

A coded media packet over borrowed bytes.

Pacer

Admits at most fps frames per second.

Passthrough

The v1 encoder: a JPEG frame from the sensor is already a packet.

Enums

Codec

The coding of a packet’s bytes.

H264Path

Where the H.264 bytes come from on a given chip.

Job

What the consumer will do with the frames.

Constants

VERSION

Crate version, for capability manifests and logs.

Traits

PacketSink

Something that accepts bytes in order.

PacketSource

Something that produces coded packets on demand.

VideoEncoder

Turns frames into coded packets.

Functions

codec_for

The policy, as a function of the job and the chip.

fmt_u64_pub

Write a decimal u64 into buf; returns the digits as a &str. No alloc. Public for the backend crate’s HTTP responder.
