Holo Video Chat

Holo Video Chat is a port of WebRTC Video Chat for the HoloLens 2. It adds Universal Windows Platform support for the C# API’s ICall, IMediaNetwork and IVideoInput.

Use it as standalone to connect several UWP applications or in combination with WebRTC Video Chat to connect to classic Windows, Mac, iOS or Android. Streaming directly to a browser is also possible with the open source library awrtc_browser.


The asset also includes example apps using MRTK 2.8:

The UWP CallApp example is a 1-to-1 video chat embedded in a MRTK Slate. It can be used to create several parallel active connections from HoloLens 2 to other supported platforms.

The HoloGuide example is a HoloLens 2 specific app that allows the user to share their physical camera optionally with holograms, eye tracking and audio. This is an ideal starting point to develop your own applications for remote training and support.
