nanoStream Webcaster Client Release 5.11.0

We have released the nanoStream Webcaster Client 5.11.0.

Release Notes

This new version adds a new feature to the nanoStream Webcaster live streaming platform. You can now add a new source type based on HTML5 canvas or other stream sources to enable user-generated live sources, separate to live camera or device screens.

To use this feature, a new API call was added. It adds flexibility in terms of what
you can present to your customers and covers a wide range of additional use cases: setMediaStream().

Possible Use Cases

• Mixing of different video sources into one stream
• PIP (picture in picture)
• Mix of different audio sources
  
• Preprocessing of video and audio in the browser
• Video overlays, e.g. rendering animations, drawings, watermarks and logos
• Use any HTML5 canvas as a live source

General Workflow

1) Acquire different video/image and/or audio sources
2) Mix sources into one MediaStream

• Video: in a canvas, write your render loop where you mix the sources via HTML canvas drawing
• Audio: with the WebAudio API

3) Pass the resulting stream to the webcaster API

Resources

• Access audio and video devices
  
• Capture a screen share or an application window    
• Creating a MediaStream from an HTML canvas
• Create MediaStreams with the WebAudio API

Samples & Documentation

Please refer to the following, included samples:

• “webcast_external_mixing_sample.html” or online via this link (please replace XXX with your API key)
• “webcast_external_stream.html” or online via this link (please replace XXX with your API key)
  

Restrictions

• You are in control of the resolution and framerate of the stream, the render loop is in your control.
• You are responsible to write a render loop that roughly maintains the target framerate.
• The mixed stream must not change resolution during the webcast (before calling stopBroadcast()).
• The mixed stream must not be ended or deleted during the webcast.
• The browser tab has to be in focus while the webcast is running (tab-throttling).

5.11.0
Added

• API call setMediaStream(): Allows passing an external MediaStream object to the API. The stream will be used for broadcasting instead of the internally created stream via startPreview().
