Announcements

HTTPS requirement coming soon — Due to new upcoming security policies in browsers, all OpenTok-powered web applications will have to be served from secured (HTTPS) sites to access the camera and microphone. Unsecured (HTTP) sites will no longer be able to implement voice, video, or screen sharing through the OpenTok platform.

Our current estimate is that these security policy changes will go into effect for Google Chrome in October 2015, with the release of Chrome 47. We suggest you go ahead and make the migration to reduce the chance of disruption to your application.

However, pages served over http://localhost can still access the camera and microphone (for local testing) in Chrome 47 Canary, and we assume that this will be the case in the stable version of Chrome 47.

OpenTok Plugin for Internet Explorer — The OpenTok Plugin for Internet Explorer enables OpenTok sessions in Internet Explorer. The plugin now works in Internet Explorer 9 - 11 (not supported in 64-bit mode). For information on testing your app with the OpenTok Plugin for Internet Explorer, see Developing with the OpenTok Plugin.

Discontinued support for Internet Explorer 8 — We have discontinued support for IE 8 in the OpenTok plugin for Internet Explorer.

Migrating from older versions — If you are moving code from version 2.0, see Migrating from OpenTok.js 2.0. If you are moving code from version 1.0, see Migrating from version 1.0 of the OpenTok JavaScript library.

Known issues

The following are known issues for this version of the OpenTok on WebRTC JavaScript library.

Issues subscribing to screen-sharing streams You cannot subscribe to screen-sharing streams in OpenTok.js version 2.2. To publish or subscribe to screen-sharing streams, upgrade to version 2.4.

Repositioning and resizing Publisher and Subscriber elements. Do not reparent a a Publisher or Subscriber in the HTML DOM. You can reposition these elements by changing style properties. See this information on resizing and repositioning videos.

One Publisher in the OpenTok Plugin for Internet Explorer. You can only add one Publisher (within all browser windows and tabs).

Cannot hide a Publisher or Subscriber in the OpenTok Plugin for Internet Explorer. Attempting to hide the a Publisher or Subscriber (by setting style.display to "none" or visibility to "hidden") causes Internet Explorer to crash.

Issue subscribing to your own stream in Internet Explorer. In Internet Explorer, you cannot subscribe to a stream published by your own client.

The OpenTok Plugin does not support 64-bit mode in Internet Explorer. The plugin works in the 32-bit mode only.

Sessions disconnect unexpectedly in Internet Explorer 9. We have seen this issue occur occasionally if there are other clients publishing streams in the session when the client using Internet Explorer connects. If you experience this problem, please let us know at the TokBox Plugin forum. (Please provide details, including the version of Windows, the version of Internet Explorer, the version of the Plugin, the URL of the app, and what was led up to the session disconnecting. You can get the version of the plugin by entering TBPlugin.version() in the console.)

Issue updating the OpenTok Plugin for Internet Explorer. When updating older versions of the OpenTok plug-in for Internet Explorer (prior to 2.6.0), users will be asked to install a new plug-in (instead of update). Installing the new plug-in will cause the update to take effect

audioLevelUpdated events are not dispatched by the publisher in Internet Explorer.

Issues setting video source for a Publisher in Firefox. In an page loaded via HTTPS, if the user clicks "Always Share" when granting access to the camera, you can only use that camera. You cannot set the video source to another camera.

Unable to initialize two publishers synchronously in Firefox and Internet Explorer. In Firefox and the OpenTok Plugin for Internet Explorer, while the user is being prompted to grant a publisher access to the camera and microphone, you cannot initialize another publisher. You need to wait for the first Publisher object to dispatch the accessDialogClosed event before instantiating a second publisher.

The OpenTok plugin for Internet Explorer does not work in sandboxed iframes. This is an intentional limitation of the browser. The browser blocks plugin content inside a sandboxed frame.

WebRTC is a peer-to-peer protocol, and it is possible that connections will fail to connect. The most common cause for failure is a firewall that the protocol cannot traverse. When OpenTok detects this failure, the TB object dispatches an exception event object, with the code property set to 1013.

You cannot publish using WebRTC on a page loaded from a file:// URL. You need to load the page from an http:// URL. For example, you can test a file from http://localhost if you have a web server set up on your local machine.
