■ Contents (subject to change)
2020 has been a year all about remote workflows, streaming content, and imagining new approaches to solving the challenges of events – both physical and virtual. There are lots of ways to stream your own events with TouchDesigner, but where do you get started? What tools should you use? What kind of a pipeline makes sense? How can you make sure your decisions will scale easily, or work on multiple computers?

In this workshop we’ll look at a workflow that uses TouchDesigner to control OBS (Open Broadcaster Software) with WebSockets. It’s often tempting to do a whole project with just TouchDesigner, and while there are lots of ways to steam directly to the web with TD, it can often be helpful to break apart your pipeline both for efficiency and to safeguard against the unexpected. We’ll start the workshop by talking through possible video and hardware configurations, and then look at how we can use WebSockets to help create systems for remote control of OBS. We’ll see how to control OBS when it’s running on the same computer, or another machine altogether.

Finally we’ll look specifically at how we can use a Python Extension in TouchDesigner to change scenes, set transitions, adjust audio controls, control your stream and record your output. By the end of this workshop you’ll have a custom widget that you can use for streaming your own virtual events with OBS.

Topics covered in this workshop will include:

Streaming pipelines and system flow
WebSockets
Python Extensions in TouchDesigner
Custom Parameters
OBS (Open Broadcaster Software)
Controlling OBS from TouchDesigner
Changing Scenes
Setting Transitions
Adjusting Audio Levels
Start and Stop Recording
Start and Stop Streaming

Matthew Ragan

Matthew Ragan, a California native, earned his BA from the California State University in Fresno. After graduation he moved to New England where he worked with Keene State College from 2005 – 2012. His time in New England was spent working for Upward Bound, an educational outreach program, and for the Center for Engagement, Learning, and Teaching as a specialist in educational media creation and distribution. Much of his work with academic technology centered on free or affordable online tools for creating and distributing web-based content. During his time in the northeast he also trained with the New England Center for Circus Arts developing skills in partner acrobatics, static trapeze, and aerial fabric.

His personal work continues to explore the intersection of digital media, live performance, and interactive installations on scales both massive and intimate.
