[Release 8] Upload Thumbnail (Preview)

[ferishili]

This PR fixes #291,

Description

When uploading a video, user is now able to either upload a thumbnail file or select a timepoint in the video to extract thumbnail from.

How it works

Configurations

• In Plugins configuration, there is now a new sub tab under Settings > Thumbnails
• In that config page:
  • admin should enable the thumbnail upload
  • admin needs to select the accepted file types for the thumbnail file to be uploaded
  • admin needs to select a mode to provide the possible ways of uploading thumbnail (either by timepoint or file upload)

Opencast Configuration

This feature depends on installing new workflows and encoding profiles in the Opencast System. Please use this document for more info:

Documentation_ Upload of thumbnail.pdf

Encoding

• /etc/opencast/encoding/manual-thumb.properties

fast workflow (if in use)

• /etc/opencast/workflows/fast-with-thumbnail-support.xml

schedule-and-upload workflow (if in use)

• /etc/opencast/workflows/schedule-and-upload-with-thumbnail-support.xml
• /etc/opencast/workflows/partial-publish-with-thumbnail-support.xml

Upload page

• There is a new section in upload page called "Thumbnail"
• depending on the admin selection for mode, users will see:
  • a switchable group of ui components if "Both modes" is selected, by which users can only select one way: either by uploading a file via File Input or selecting a timepoint via Timepicker.
  • Only a file input if "File Upload" is selected
  • Only a Timepicker input if the "Timepoint" is selected.
• The "straightToPublishing" workflow param value from the configuration is also reflected in this page, by providing related infos or disabling the section if the value is set to always inactive!

NOTE: As for uploading the file, we had to use ingest mechanism, therefore, you would need to make sure that the uplaod by ingest is configured in your Opencast!

How to test:

• Opencast 15 and above.
• ILIAS 8
• Patch this PR.
• Configuring the thumbnails settings in plugin config. (Check different options and their outcomes)
• Upload video:
  • Upload thumbnail
  • Select a timepoint (the timepoint is smart, which means it gets the duration of the selected video and does not allow you to go beyond the duration by each you select a video)!
  • Both modes should also cover the above scenarios.

NOTE: Please help adjust or improve the German texts!

We tested it and had some issues with applying the new workflows to our configurations. It works now, but it could cause issues with customized setups.

ILIAS version: (v8.12 2024-05-28) PHP version: [PHP 7.4.33] Plugin version: [8.0.3] Opencast version [15.5.0] Browser: [chrome]

[ferishili]

Thank you @tscheere Happy to hear that. It is worth noticing that, the workflows are based on the default workflows shipped with the opencast, therefore, it requires obtaining any customization applied to those old-workflows in your setups!

[ferishili]

@dagraf, is there anything needed here? I am labeling this as ready to merge, just adjust it if something is still needed.

[dagraf]

No. Since @tscheere did test and approve this PR it is ready to merge.
