Supported Formats for Media Objects
Pagina overzicht
[Verbergen]1 Initial Problem
Traditionally ILIAS allows to upload all kind of file types to media objects. However it is unclear how all these types are supported or rendered when embedded, e.g in pages. Some formats needed special browser plugins, others have been abandonded by the web community completely (applets, flash).
2 Conceptual Summary
ILIAS will only support the following file types for being uploaded/referenced as media objects:
- Images: png, jpeg, gif, svg, webp
- Audio: mp3
- Video: mp4, youtube (external reference), vimeo (external reference)
- HTML (iframe)
- PDF (limited, since behaviour of embedded PDF viewers highly depend on OS/browser)
Here some examples of file types / reference types that will not be supported (anymore):
- Flash, Java Applets, wav, webm, quicktime, ogg, Flickr, Google Docs, pptx, xlsx, docx, general "embedd" tag
3 User Interface Modifications
3.1 List of Affected Views
- Administration > Repository and Objects > Settings
- Media Pool / Page Editor > Add Media Object
3.2 User Interface Details
3.2.1 Administration > Repository and Objects > Settings
The input for "Allowed File Types" will be removed. The input for "Forbidden File Types will list the currently supported types.
3.2.2 Media Pool / Page Editor > Add Media Object
The creation dialogs will only accept the defined file types.
3.3 New User Interface Concepts
No new interface concepts
3.4 Accessibility Implications
No accessibility implications. The limitation to a defined set of file types will make it easier to address these in the future specifically.
4 Technical Information
No technical issues.
5 Privacy
Current state of privacy in Media Object service see https://github.com/ILIAS-eLearning/ILIAS/blob/trunk/Services/MediaObjects/PRIVACY.md.
This feature does not implement any privacy related changes.
6 Security
The limitation on certain file types will increase security.

9 Discussion
JourFixe, ILIAS [jourfixe], 03 APR 2023: We highly appreciate this suggestion and schedule the feature for ILIAS 9. We would like to support WebM, too - in case this format will be supported by the KS Audio/Video Player.
