retina

High-level RTSP multimedia RTSP streaming library, in Rust. Good support for IP surveillance cameras, as needed by Moonfire NVR.

Progress:

• client support
• • digest authentication
• • RTP over TCP via RTSP interleaved channels.
• • RTP over UDP. (Shouldn't be hard but I haven't needed it.)
• • SRTP
• • ONVIF backchannel support (for sending audio).
• server support
• async
• • tokio
• • async-std. (Most of the crate's code is independent of the async library, so I don't expect this would be too hard to add.)
• codec depacketization
• • video: H.264
• • • SVC
• • • periodic infra refresh
• • • partitioned slices
• • audio
• • • AAC
• • • • interleaving
• • • RFC 3551 codecs: G.711,G.723, L8/L16
• • application: ONVIF metadata
• uniform, documented API. (Currently haphazard in terms of naming, what fields are exposed directly vs use an accessors, etc.)
• rich errors. (Currently uses untyped errors with the deprecated failure crate; some error messages are quite detailed, others aren't.)
• released versions of all deps. (crates.io publishing requirement.)
• good functional testing coverage. (Currently lightly / unevenly tested. The depacketizers have no test coverage, and there's at least one place left that can panic on bad input.)
• fuzz testing

Help welcome!

Why "retina"?

It's a working name. Other ideas welcome. I started by looking at dictionary words with the letters R, T, S, and P in order and picking out ones related to video:

$ egrep '^r.*t.*s.*p' /usr/share/dict/words'
retinoscope	close but too long, thus retina
retrospect	good name for an NVR, but I already picked Moonfire
rotascope	misspelling of "rotascope" (animation tool) or archaic name for "gyroscope"?
