Congratulations, you got your brand-new TUM-Live account. What's next?

Setup your account.

You probably already got an email telling you to setup a password for TUM-Live. If not, request it at multimedia @ rbg.in.tum.de. Use the link in the email to set a password. You can now login with your email address and your password.

Create a lecture

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. But where can we find this ID? Here!. 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 and add a short name to your lecture. E.g. Lecture 1: ISO/OSI model

Set up OBS

Upon opening OBS the first time, you are greeted with a setup page. Skip this, we'll set everything individually. In OBS's settings navigate to Output and set your video bitrate to about 2000 Kbps. If you experience issues, you might get away with less. Under Video make sure that your resolution is 1920x1080 or at least in 16:9 aspect ratio.

Get your stream Key

In the admin panel you'll find your streaming key and a server URL:

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

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

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.

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 of start and end:
