Create a course

This screen is what you're greeted with. Simple enough right?

There's a few things to consider:

• TUMOnlineID
  • This field is recommended for all courses that have an associated course in TUMOnline. Setting this value allows you to make the course public to enrolled students only. Also your course will be placed more prominent on the homepage if you set this field. This is where you can find the right ID. After clicking "load info from TUMonline" other fields are filled in automatically.
• Teaching Term needs to be in the form Sommersemester YYYY or Wintersemester YYYY/YY.
• slug Is a short handle for your course. Example: Grundlagen Rechnernetze und Verteilte Systeme could have the slug grnvs. The Slug is unique per semester.

Schedule your Lectures

If you provided a course ID, the lectures are added automatically. You can always add more lectures at the bottom of the page. If you want, help your students out, add a short name to your lectures. E.g. Lecture 1: ISO/OSI model

Set up OBS

Upon opening OBS the first time, you are greeted with a setup page:

• Optimize for streaming
• Base Resulution should be 1920x1080 or at least 16:9 aspect ratio, FPS is not relevant. If you don't want to livestream a let's play, students might benefit from faster loading times if you choose 30 fps.
• Service: Custom. Uncheck Estimate bitrate with bandwidth test and fill out Server and streaming key with dummy value for now. (E.g. rtmp://live.mm.rbg.tum.de and abc). 2000 Kbps should be fine, you can get away with less if your connection can't handle the default.
• Apply settings

Get your stream Key

In the admin panel you'll find your streaming key and a server URL. These are unique for each lecture currently:

Copy both into OBS's Stream settings Server and Key respectively.

In OBS add your scenes and sources as you wish. Note that screen-capture is a lot less performant on linux devices than window-capture.

You are ready to start the stream! It's recommended to start streaming a few minutes early to give students a chance to come in in time.

Pausing your Stream

If you want to pause your stream, feel free to do so by just hitting Stop Streaming in OBS. Pauses can be up to two hours long. After this timespan, the video will be processed and uploaded as VoD. If you use a seperate scene for pausing your students don't need to reload the page when you start the stream again though.

After the Stream

Give our (and the LRZ's) infrastructure some time. Within ~1-2 hours, your stream will be marked as VoD in the admin panel. If you wish, you can now access stream stats, hide the VoD, download the recoring or cut off start and end:
