nanoStream and Google Chrome


In Chrome version 42 introduced in April, 2015, Google changed the default setting for NPAPI plugins like nanoStream from “enabled” to “disabled”. You can re-enable NPAPI support by changing the Chrome Flag. This setting will be removed from Chrome in September 2015, when all NPAPI plugin support from Chrome will be discontinued.

nanoStream Product Options for Web Browsers

All nanocosmos customers will be able to proceed using our nanoStream technology in desktop browser environments. We will
keep providing solutions and updates to our web based live video encoder software along with new browser technologies.

You have these options:

1) nanoStream Web Plugin

nanoStream 2.x and 3.x, as available now, are based on NPAPI and Active-X.

Please check
How to enable NPAPI plugins in Chrome to manually enable NPAPI plugins in Google Chrome.

You find the latest nanoStream Live Encoder Web Page and nanoStream plugin update 3.x here for download, which should enable NPAPI automatically during setup.

All other browsers on Windows and MacOS, Internet Explorer, Safari, Firefox remain unaffected and continue working with NPAPI. So you will always have the option to use the builtin browsers (Internet Explorer and Safari).

2) nanoStream 4 – as available in Q3/2015 will include an updated plugin which will continue to work in Chrome beyond 2015 and 2016.

3) nanoStream WebRTC extension

available now, is based on a different client technology and requires nanoStream WebRTC-RTMP server bridge.
Click here for more information to connect WebRTC clients to RTMP streaming environments.

nanocosmos will continue to provide updates to our technology based on our own product roadmap and customer feedback to maintain compatibility and interopability to existing and future technologies.

Please contact us for details or book our consulting services.

Background info about NPAPI Plugins

The NPAPI technology is based on native C/C++ code which enables system-level functions in custom plugins within browser environments. Google considers this a security risk, as it is not “sandboxed” as other technologies. Until now, NPAPI is the only plugin technology available on all browsers and desktop platforms (except Internet Explorer, which is using Active-X).

Showcase: Live Music Video Streaming for TV Broadcast

nanoStream is being used for a Live Music Video Streaming TV Show for, powered by

Based on our nanoStream Toolkit for Windows, we are using a customized encoder software to provide the best possible integration into a Live TV production environment.
The project is a cooperation between nanocosmos, Fernsehwerft Berlin and

Specific requirements were solved with the software solution which not otherwise would have been possible to easily:

  • Live Video Encoding of 2xRTMP Streams (SD and HD), and 5xHLS streams to directly ingest into a broadcast CDN
  • Seemless integration of a Meta Data ingest UI to trigger remote ad-insertions
  • flexible easy-to-user interface with preconfigured streaming setups

    The software is based on the nanoStream SDK, a easy-to-use software toolkit to create live video encoding applications.
    The HLS Encoder is being used in 2 live shows, the songbook series showing live music shows, and the roomservice series.
