Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

yellowstone v3.0.1

NPM

The RTP/RTSP client for Node.js.

npm install yellowstone --save

Getting Started

Yellowstone is a library to receive raw data from RTSP/RTP. The library (at this time) makes little attempt to parse the raw data it receives, and puts that weight on the library user themselves. Transports (such as for H264) may be suitable as-is or as a starting point for your own work.

Yellowstone was co-developed by Michael Bullington and Roger Hardiman.

Current Features

  • Raw RTP/AVP via UDP & TCP (interleaved)
    • Basic and Digest Authentication
    • Pause, Play, and Teardown (Close)
  • Simple RTCP parsing
  • Simple H264 transport parsing
  • ONVIF extensions to RTSP

In the future, Yellowstone plans to support:

  • Record and Announce Methods
  • Full Client RTSP support

Examples

An example of most API features can be found at examples/wowza.js, which will create a file named bigbuckbunny.264 in the project's root directory. To test this file with a video player, you either need a video player that supports raw H264 frames, or wrap it in a container like MP4.

While yellowstone is /not/ dependent on ffmpeg, converting the file to an .mp4 can be easily accomplished with the following command.

ffmpeg -f h264 -i bigbuckbunny.264 bigbuckbunny.mp4

If you wish to play the H264 file directly, I've had good experience personally with the IINA video player for macOS. VLC and FFPLAY also work.

Documentation

You can find auto-generated documentation in the docs folder.

Contributing

Please contribute features!

Yellowstone covers a very small subset of what's possible with RTSP/RTP. Feel free to write and submit pull requests for easy to use abstractions of protocol extensions (such as ONVIFClient), as well as core features and bug fixes.
