This user guide helps you to play u:stream recordings via the u:stream Player.


The screenshot shows a test stream in which both the camera and the projector image are recorded.
Which variants are actually offered depends on which selection the teachers make for streaming the course.

You can see the following elements here:

  • video area
  • Timeline with chapter indicators
  • Controls (play, pause, volume etc.)
  • Title of recording with date
  • Description, keyboard shortcuts, slide text

Video section

Depending on which recording variant was selected, you will see the recording of the camera, beamer image or both sources here.
If no image source was selected (i.e. only audio was recorded), this area remains black.

Timeline with chapter indicators

The timeline can be controlled by clicking and dragging the slider.

The chapter indicators are automatically created by the system when strong changes in the beamer image or cuts in the camera image are detected (for example, during a source change). The indicators are used for orientation in the stream and can be addressed directly by clicking on the area in front of the indicator.

Control buttons

  • Zurück (Back) = Jump to previous chapter
  • Play/Pause = Start or pause the stream
  • Vorwärts (Forward) = Jump to next chapter

Time indicator
In the middle area you can enter a time in the format hh:mm:ss. By pressing Enter, the video jumps to the specified timecode.


  • You can zoom into the video by selecting a zoom level from the drop-down menu (100, 150, 200 and 300 % zoom are possible here). Clicking on Reset in the drop-down menu restores the original zoom level (100 %).
  • Alternatively, you can move the mouse over the video and use the scroll wheel to zoom in or out.
  • The image section can be moved by dragging it with the mouse (while holding down the left mouse button).

Set speed

  • Changing the speed is only possible if this option has been activated by the teacher.
  • The speed can be reduced to 75% or increased up to 300%. The remaining running time of the video at increased/decreased speed is indicated in brackets. For example: 200% (00:45:00)
