The Temasys Plugins bring support for webRTC to Desktop versions of Safari and IE.
There is no solution to provide support for iOS versions of browsers at this stage.
We do however provide support for iOS and Android native apps. Visit Skylink.io for more information.
The Temasys WebRTC plugin implements the WebRTC spec as closely as possible. It implements the latest published draft, not working draft, and in case of ambiguity, will always align its behavior with the latest stable version of chrome and firefox.
It should work with existing code with only minor changes to the site. However for a site to take advantage installing the plugin on the target computer is not enough. We provide a modified version of adapter.js, a helper file originally provided by Google and Mozilla to help interaction between browsers.
You can download the plugin installers here:
I installed the plugin, now what?
You can try it on our public demos here:
https://plugin.temasys.io/demo/ – A series of tests first provided by google that were made plugin aware.
Do you have a technical issue with the plugin? Do you have a feature request?
Let us know in our customer support portal : http://support.temasys.io.
Our plugin discussion group (discontinued) also has a wealth of information: https://groups.google.com/forum/#!forum/temasys-discuss-webrtcplugin
Do you have a commercial request? Do you want more support, to rebrand, redistribute, or embed the plugin? Do you have a feature request beyond the webRTC existing webRTC specs?
Commercial request should be sent to firstname.lastname@example.org
Like it or not, IE still matters
You can ignore reality, or you can reach more users. You can do it yourself but that’s also hard. We make it easy, so let us help!

*With the release of the latest version of Safari, Safari 12, Apple has decided to remove support for third party NPAPI plugins in Safari. This means that third party plugins, including the Temasys WebRTC Plugin for Safari, will no longer work with the new version(s) of Apple Safari. Safari versions prior to Safari 12 can continue to use the Temasys WebRTC Plugin as detailed here.

namespacing of the plugin, the webrtc interface stays the same, you dont' need to change your code
All Temasys related code is located in
All plugin related code is located in
- You should now access the plugin through Temasys.WebRTCPlugin.TemRTCPlugin
- Two different injection strategies for IE 9 (or less) and any other browser
- new popup offering to install the plugin
- WebRTCReadyCb is deprecated, you should remove it from you code. You may now call any webrtc function at any time.

Please note that our examples are using the latest version of the adapter.
- New auto-update popup (same style as for the plugin install popup)
PeerConnection::onicecandidate argument is now a RTCIceCandidate object instead of a simple dictionary
For the DataChannel to be able to send non-string element, the variable Temasys.WebRTCPlugin.TemRTCPlugin needs to be one access to the plugin
You must define Temasys.WebRTCPlugin.TemRTCPlugin as a variable, not a function, although typeof Temasys.WebRTCPlugin.TemRTCPlugin might return function
If you're using the adapter, this is already taken care of.
This declaration no longer needs to be part of your code

This declaration MUST be part of your code (if you're using our extension of adapter.js, this is already taken care of)
- The DataChannel can send the following types:
See WebRTC Plugins for more details
A new parameter is needed for the <object> plugin element:
Adding the parameter
to the plugin element will enable the listing of all devices referenced on your computer (including unplugged devices, virtual devices, and so on)
See WebRTC Plugins for more details.
