Opencast Summit 2025 Graz: Call for Participation

Large parts of the summit will have an unconference style, with a lot of room for discussions and working groups. You can also already suggest sessions in advance following the link above, but you will still be able to suggest topics ad-hoc on site where we will schedule the unconference sessions according to interest.

Moving from Google Groups to GitHub Discussions

It is finally time to do the move from Google Groups to GitHub
Discussions. The groups users@opencast.org and dev@opencast.org have been archives and are only accessible read-only from now on. For any further discussions or questions, please go to:

Not all groups have been migrated. Some sub-communities like anwender@ or lms@ still exist on Google Groups for now. We can migrate additional groups if those communities want that.

If there are any problems, ping us on Matrix.

Matrix room (Chat)

Not a replacement, but an additional place for quick questions or just to chat is our Matrix community. Join the Matrix space #opencastproject:matrix.org and in particular, the community channel #opencast-community:matrix.org.

Also, the room #opencast-announcements:matrix.org will from now on get a copy of messages posted here and sent to the announcements list.

See you on GitHub!

Admin Interface BugBash: Thank you!

This week lots of community members participated in an Opencast BugBash to help to improve the new admin interface and get rid of a lot of minor, yet annoying little bugs which were still present in the project.

The event turnout was great. We had admins probe for problems and report not only those but a lot of big ideas for small improvements which can make the life of admins easier. We had developers, including some new ones, picking up the reported issues and fixing what needed to be fixed. And finally, we had community members reviewing the new patches to ensure they actually fix the issues and do not cause new ones.

Further Work

The new version of the admin interface will be part of Opencast 16.0 which is to be released next week. If more patches make it in, there will likely be another admin interface release in preparation for that.

While we have fixed so much, there is quite a bit of work remaining. We identified many issues and a number of them are still open and needs fixing. We also have open patches awaiting reviews. This means that your help is still appreciated.

If you want to help in any way (testing, development, money), but don’t know how to best address this, don’t hesitate to talk to the Opencast Board.

Finally, let me close this post with another thank you everyone for all your help!

Admin Interface BugBash on June 4-5, 2024

The new admin interface has a bunch of minor, but still very annoying
bugs. To address this, there will be an Opencast BugBash focused on
the new interface (though no one will complain if you fix other bugs).

The idea for these two days is to bring together as many people as possible to identify bugs, fix them and review the resulting patches so that we can get them into Opencast prior to the release of Opencast 16.

If you want to help, that would be great. We need…

  • admins and users testing the new user interface to create issues
  • developers to fix issues and create pull requests

To participate just show up at the meetings, visit our Matrix channel at #opencast-community:matrix.org or just work in GitHub.

You cannot make it but want to help regardless?

  • You can already start identifying problems and file them as an issue. Please also file usability issues, or other suggestions for improvements.
  • You can put money into hiring developers from the usual suspects when
    it comes to experience with Opencast development.
  • You can help to translate the admin interface on Crowdin.
