GoCast vs PuMuKIT

GoCast is a self-hosted platform for streaming and recording lectures. Organizations can run it on their own servers, keeping streaming data processing and storage under their control. It can automatically stream auditorium lectures according to schedules, while lecturers can also stream using OBS, Zoom, or other software. Lecturers manage videos through a self-service interface, and course and student enrollment information can be imported from CAMPUSonline. Live streams are recorded automatically, and video-on-demand uploads are supported. Post-processing can detect silence, create searchable transcripts, and generate thumbnails. Live chat lets listeners ask questions and upvote them; lecturers can run polls and mark or hide questions. Course access can be public, limited to enrolled or invited users, or restricted to users logged in with an LRZ ID. GoCast is open source under the MIT license and listed as free. Deployment requires worker or runner servers and shared storage. Its self-streaming guide warns that streams may be unreliable and recordings may be corrupted, and recommends keeping a local copy.

PuMuKIT is a free, open-source video platform for organizations with large collections of video or audio. It can run a complete media site on an organization's own infrastructure, with a customizable portal for browsing by series and category. Portal widgets can surface related, most-viewed, and recently added videos. Publisher tools include drag-and-drop cataloguing, autocomplete, interactive forms, and UNESCO science and technology tags. An Opencast module supports presenting and cataloguing Opencast videos in the portal. The site describes distribution to services such as YouTube and iTunes U and learning systems including Moodle and Open edX. Organizations can provide live event channels and keep recordings available on demand. Playback supports HTML5 and Flash, with the portal described as usable in desktop browsers and on Android, iPhone, and iPad. The downloads page lists PuMuKIT 4.2.4 as the latest stable release and recommends it for production. Version 4.x is based on Symfony 5 and MongoDB. Community support is offered through mailing lists in English and Spanish. Older 1.x, 2.x, and 3.x versions are not community-supported.
