Opencast is an open-source video-management system, mostly used in higher education. It has a wide variety of learning management integration (Moodle, Ilias, Stud.IP, LTI), includes a browser-based recording tool (Opencast Studio) and supports automated recordings in classrooms. The Opencast player supports the playback of multiple synchronous video-streams and features several other unique features, like a zoom into the video.

The purpose of the Worpress-Opencast-Plugin is an easy to use, secure and reliable integration of Opencast into WordPress for administrators, authors and viewers. The plugin features the ability to upload videos to Opencast, create videos with Opencast Studio and easily include the Opencast Player and restrict access to the recordings based on Worpress roles.

There is currently no public WordPress demo instance with the Opencast-plugin installed available.
