Streaming your jam on Mixer

For 2019, Mixer are headline sponsors for Global Game Jam. We will be using Mixer as our main streaming platform this year. TODO add in Mixer link and directory link.

There are two elements to this - managing your own jam stream, and broadcasting on the GGJ central stream.

Also we encourage all sites to show the central GGJ stream on a screen or projected on the wall - so your jammers can seen snapshots from sites all around the world!

If you do stream, be careful you don't reveal the theme until the time is right!

Setting up a stream for your jam site

If you have the internet bandwidth and the equipment, it is worth setting up a stream for your site, so that others from around the world can check in to see how you are doing. See just below for the technical requirements.

The central GGJ stream will be featuring sites all around the world throughout the event! Each site who is accepted will get between 30-60 minutes to showcase what they are doing. We encourage all sites to apply, and ask for active participation, so maybe interview jammers, showcasing project, a tour round your building - something that will be fun and engaging for our viewers. Applications to be part of the central stream open early December, and the link will be added here when ready.

Technical requirments <-- TODO check these are up to date

To get your site broadcasting you will need:

  • A computer to stream from, preferably one not being used for any other tasks

  • A suitable camera to capture video for your stream

  • Broadcasting software to stream your video feed to the world

  • A reasonably fast and reliable internet connection

  • A Mixer account

  • The Global Game Jam and Mixer code of conduct


The recommended specs for a streaming computer are as follows:

  • CPU: Intel Core i5-4670 or AMD Equivalent (use this tool to compare your CPU)


  • OS: Windows 7 or later

  • GPU should support DirectX 10 and up

If you can, we recommend that you have a computer set aside exclusively for streaming. If your computer doesn’t have to share resources among multiple tasks, you will produce a smoother, higher quality video feed.


The Logitech C920 is a widely-used webcam by broadcasters. For streamers using a camera with an HDMI connection, we recommend the Magewell USB 3.0 dongle.

Broadcasting software

To broadcast, you'll need broadcasting software. This is the program that will encode video and audio information from your camera feed and send it to a streaming platform for broadcasting. There are several software solutions to choose from, including:

Once you choose your software, spend some time getting to know it. Play with the settings, and run some test streams and ask for volunteers to watch it and give feedback on the video and audio quality. Don’t leave your stream setup until the first day of the jam only to find that something isn’t working!

Internet connection

Venue bandwidth: For a smooth stream, 5 Mb/s upload is recommended, and if possible it should be an isolated connection that is not impacted by traffic from other users. If you notice that your streaming software is dropping frames at any point, consider lowering the video quality.

Accounts set up

Mixer account

Of course, you’ll need a Mixer account. Read more about how to set this up on the Mixer getting started guide.

Register for the GGJ directory page

In order to be featured on the Global Game Jam® directory, you will need to <-- TODO add this once we know how

Mixer server

It is usually best to connect to the ingest server closest to your venue, <-- TODO how doo sites find their nearest mixer server, and how do they connect?

Be sure to set the “Live stream link” on your GGJ site page to the URL of your Mixer stream page. This way, anybody visiting your page will be able to easily find your stream.

Code of conduct

Before starting your stream, please read the GGJ inclusiveness policy and code of conduct and adhere to them at all times during broadcast. These documents exist so that everybody can have an enjoyable and safe game jam, so any site broadcast that breaches them may be removed from the directory without warning. You will also need to adhere to Mixer Rules of user conduct and Code of Conduct.
