Opencast 6: Release Notes
- Asset Manager Storage Layers - The Asset Manager now supports multiple storage layers natively. This allows users to move data from local storage to remote storage within Opencast. These moves can be triggered manually, or via a built-in timer. Currently we support local file storage, and AWS S3 storage.
- Video Editor - Thumbnails - When displaying lists of videos, thumbnails are usually used to make such lists more appealing. The video editor allows the user to choose between the default thumbnail (automatically created), a snapshot thumbnail (extract at current position from video stream) or an uploaded thumbnail. This allows the user to get the best thumbnails for his videos with as little effort as possible.
- Video Editor - Track selection - In case multiple tracks have been ingested, the video editor allows the user to choose which tracks should be processed. In case of a dual track lecture recording, the presenter track could be exluded from publication in case the recorded person would want this.
- Keyboard Shortcuts - A per page keyboard shortcut list is available so that users can at any time and page see what keyboard shortcuts are currenlty available.
- External API 1.1.0 - For the first time, Opencast takes advantage of its state-of-the-art versioned API by introducing the External API 1.1.0. The new version extends the API to support scheduling of events and access to workflows. The filter and sort facilities have been extended and additional fields are directly delivered by some core requests with allows clients to access them way faster. The External API 1.0.0 is still supported relieving existing clients from the need to be timely adapted.
- Processing Settings Persistency - A new persistence layer for processing settings has been introduced. This allows the Admin UI to not just provide processing settings as input when starting workflows, but also to display processing settings on event basis.
- Capture Agent Access Management - The Admin UI now supports access management for capture agents. This features addresses the need to allow unprivileged users to access the Admin UI to manage their own content and cut videos without allowing them to schedule events or change the scheduling as this task is usually in the responsibility of a dedicated team. It is also possible to permit users access to specific subsets of the available capture agents.

- The introduction of capture agent access management implies that unprivileged users do not have access to any capture agents by default. To allow otherwise unprivileged users to interact with event scheduling, you need to configure their access permissions appropriately. For more details, take a look at the capture agent access management documentation.
