Best practice: streaming server for educational videos at Universities

[EN]In this paper we present a video streaming solution. It describes the functionality of streaming server at our university and the workflow to embed videos into the learning platform Moodle. By the server-side role management teachers can get access to upload their recorded lectures to the server. Videos will be converted into different streaming formats and embed into the learning platform with provided embed code. The number of teachers who use this proposal is continuously growing at our university. Beside the lecture scripts the videos watched often by the students what the numbers of video accesses in the Moodle course and the streaming server traffic significantly show.
