YU Kaltura Media Package

"YU Kaltura Media Package" is a third-party's Kaltura plugin package (a series of plugins) for Moodle 2.9 or later. This package is developed by the Center for Information Infrastructure, Yamaguchi University. By using this package, users can upload media to the Kaltura server, and easily embed the media in Moodle courses. Moreover, this package provides some useful functions. Since this package does not require Kaltura Application Framework (KAF), can work with Kaltura Community Edition (CE) and other editions.

In order to use this package, administrators must install "YU Kaltura Media Local Libraries" and "YU Kaltura Media Gallery". These plugins provide functions such as uploading, playing back and deleting media files to users.

In addition, the administrators can install "YU Kaltura Media Assignment", "YU Kaltura Media Resource", and "YU Kaltura Media for Atto". These plugins provide teachers ability of creating resource and activity modules which use kaltura media in their Moodle courses. And, user can embed his/her media into text area (introduction or page content) through the Atto HTML editor.

Please note that there is a chance this module will not work on some Moodle environment. Also, this package is only available in English and Japanese. Stay tuned to future versions for other language supports.

Original plugin package ("Kaltura Video Package") has better functions than ours and is easy to use. So that, for customers of the "Kaltura SaaS Edition", use the original plugin package is the better.

YU Kaltura Media for Atto

This is a sub-plugin for the Atto HTML editor. By using this plugin, users can embed Kaltura media into text content. For example, introduction of resource/activity content, page content, label content, report as online text, feedback comment, etc. Users can embed existing Kaltura media into text area of the Atto. In addition, they can upload new media and can embed it. For PCs, users can record new media by using a webcam, and can upload the media. Then, they can embed the media into text area of the Atto.

    Dear users,

    We have released the YU Kaltura Media Package version 1.4.1.

    Recently, many users upload their media to our Kaltura system.
    Since the upload data goes through the front node, the increase of the uploaded media deteriorates the delivery performance of front nodes.

    So that, we have added upload URI as a plugin configuration item.
    By separating the upload node and the front node, it is possible to reduce the effect of upload on the delivery performance.
    If the upload URI is empty, the uploaded media goes to the server URI.

    Dear users,

    We have fixed the "YU Kaltura Media Resource" plugin (mod_kalmediares).
    In latest version (1.4.1R2), our plugin can update number of playback even on full-screen mode video.
