Additional Features

In this section, you can configure the chunkuploader, the access to Opencast Studio, the access to Opencast Editor, the visibility of episodes, the activity module settings, the settings for transcriptions as well as some other features.

Settings for the chunkuploader

If you also have the chunkuploader installed, you configure it in this section.

Enable Chunkupload: If enabled, it will be possible, to upload videos using the chunkupload plugin. Defaults to yes.
Video size limit: Limits the file size of uploaded videos through the chunkupload. The default is 2.0 GB.
Offer filepicker as alternative: If this option is enabled, a checkbox, labeled as 'Use Moodle default file picker to access all repositories' will be shown below the chunkupload widget. As soon as this checkbox is checked, the chunkupload widget is hidden and the Moodle default file picker is shown, giving access to all Moodle repositories. Defaults to yes.

Opencast Studio integration

In this section, you can enable the feature, to add Opencast Studio support to the block. The options are:

Show the link to opencast studio: This option renders a button to Opencast Studio in the block content and the block overview. Defaults to no.
Redirect to Studio in a new tab: If enabled, the Opencast Studio opens in a new tab. Defaults to yes.
Opencast Studio Base URL: The base URL, to be used to call Opencast Studio. The base URL of the associated Opencast instance is used, if empty. Defaults to empty.
Show a redirect back button in Studio: When enabled, Opencast Studio then renders an additional button "Exit and go back" after up- or downloading the recording. Defaults to no.
Label for Studio's return button: This label works as a short description, where the return link leads to. This label will be appended to the Opencast Studio return button text. If empty, the Moodle site name will be passed as label. Defaults to empty.
Custom Studio return endpoint URL: If empty, the return URL redirects back to the same Moodle Opencast block overview, where the request comes from. A custom endpoint URL will then be passed to Opencast Studio as return URL, if configured. In this case, an admin is able, to use two placeholders including [OCINSTANCEID] and [COURSEID]. Please NOTE: The URL must be relative to wwwroot. Defaults to /blocks/opencast/index.php?courseid=[COURSEID]&ocinstanceid=[OCINSTANCEID].
Custom Studio settings filename: This custom settings filename will be appended to the query, when redirecting to Opencast Studio. Afterwards Opencast Studio looks for that filename relative to its directory and reads its settings from that file. Note, that this feature requires Opencast 14.2 or later. Defaults to empty.

If LTI is configured in the Opencast API plugin, the access to Opencast Studio is initiated with LTI, so that users are directly authenticated.

Recommendation: It is possible, to configure Opencast Studio, to add certain ACLs to the recorded videos. It is recommended, to add the same ACLs to recorded videos as to uploaded videos via the block.

Opencast Editor integration

In this section, you can enable the feature, to add Opencast Editor support to the block. The options are:

Show the link to opencast editor in the action menu: This option renders a button to Opencast Editor in the block content and the block overview. The other settings of this section and the LTI credentials have to be configured as well. Defaults to no.
Opencast Editor Base URL: The base URL to be used, to call the Opencast Editor. The base URL of the associated Opencast instance is used, if empty. Defaults to empty.
Opencast Editor Endpoint: The Opencast Editor endpoint, to access the editor. The mediapackage ID will be added at the end of that URL. Defaults to /editor-ui/index.html?mediaPackageId=.

If LTI is configured in the Opencast API plugin, the access to the Opencast Editor is initiated with LTI, so that users are directly authenticated.

Engage player integration

If you use this configuration, the video titles in the block overview are displayed as links to the Engage player. If LTI is configured in the Opencast API plugin, the user will be authenticated with LTI before being redirected to the Engage player.

URl of the Opencast Engage server: Absolute URL to the Engage server. If empty, the video titles in the overview are not linked to the Engage player. Defaults to empty.

Notifications

In this section, you can configure, whether teachers should receive notifications about the processing status of videos after upload.

Allow event process status notification: This option allows the system, to send notifications about the status of uploaded videos from Opencast during the process to the users. This option only includes the uploader of the video in the user list. To notify all teachers of the course, the setting Notify all course teachers about the event process status should be enabled. This feature is realized through a scheduled task, that is recommended to run every minute. Defaults to no.
Notify all course teachers about the event process status: With this option, apart from the uploader of the video, all the teachers of the course, where the video is uploaded from, get notified about the Opencast processing status (see the setting Allow event process status notification). Defaults to no.
Cleanup notification jobs after (Days): This setting sets a deadline in days for the jobs, that are not yet completed. After the deadline was reached, the job will be deleted despite its process state. This features helps, to remove the pending notification jobs from the list, and it is done through a scheduled task, that is recommended to run once a day. Defaults to 0.
NOTE: (zero) "0" value disables the setting.

Allow episode group restriction: If enabled, teachers can not only control the visibility of an Opencast episode for all course users, but can also restrict the visibility to particular course groups. Defaults to yes.
Waiting time for scheduled visibility change (Minutes): It defines a minimum waiting time (in minutes), that a scheduled visibility change process should wait. This time span will be added to the current time for the scheduled video change date field in the add video form. It will also be used, to validate that field. Based on how fast the Opencast instance processes the videos, this waiting time could be configured. Defaults to 20.
NOTE: When empty or (zero) "0", the default value is used.
