VDO Ninja
Note: At the current state we can not recommend to use ninja. have a look at kevin for an alternative
VDO Ninja (previously named “OBS Ninja”) allows speakers to share their webcam or desktop over the internet using peer to peer web-rtc video streams, so the mixer can embed those streams using a browser source in OBS Studio
Voc-Hosted Service: Ninja Winkekatze
Currently Installed Version: 6

- OBS Ninja is not totally open source, for details see Issue in Github. We are currently working on a fully free version.

Features
Group Chat
Creating a new Groupchat creates a new room, for which the creator is the director.
For each Room there is one main director. It is possible to join subdirectors when there is already a main director present, but those are quite limited.
It is possible to transfer Streams from one room to another. This can be useful for e.g. creating a Waiting room and a live room. Multiple Transfers can be done quickly by selecting multiple Streams for trasfer by holding down CTRL (on Windows) or CMD (on MacOS).
Using the chroma parameter, you can change the background color of the Directors view. Use this if you have multiple rooms open, for a quick visual distinction.

Misc
Tally Light
OBS Ninja supports a Tally Light feature. This shows a red border around the preview video of the sender if the Sender is Visible in OBS (visible means either on the Live-Canvas or, if in Studio mode, on the preview Canvas).
In order to work, the Visibility of the source has to be toggled at least once already in OBS. (This means you have to switch to scenes such that the OBS Ninja Browser Source is not visible in the main window of OBS.)
TODO: Determine if sources in MultiView count as Visible.
Stats
The Stats window can be enabled either by pressing right CTRL while clicking on the video or appending the stats parameter to the URL. On Mobile devices, you can open the stats video by rapidly pressing on the screen multiple times.
The Stats window shows a lot of infos about the video stream, including but not limited to the used video codec, the resolution, the bitrate, the frames per secound, and the packet loss.
File Sharing
According to the documentation, it should be possible to share Files (Video / Audio) via OBS Ninja. As of 16.12.2020, this was not tested successfully.

Fixing Issues
GroupChat
- I can not join a Groupchat. If I am a speaker trying to join I can select a Camera and click on start, but then see only my own camera picture. The director does not see anything.
