Improve Usage of Subtitles

1 Requirements

Subtitles in Export Files

Chrome does not allow the mediaelment.js player to load srt-files per ajax from local sources (file://), see ILIAS bug .
A workaround could be to put the content of srt files directly into the html page that contains the video and to patch mediaelement.js to load this local srt content instead of getting it from the files.

Multiple SRT Upload

It should be possible to upload a .zip-file containing multiple srt-files into a media object.

• ILIAS searches for language suffixes, e.g. „..._en.srt“ to assign the files to the corresponding languages.
• ILIAS displays a confirmation screen that shows all files and their identified languages.

It should also be possible to upload a zip file containing multiple srt files into a learning module.

• ILIAS again checks for language suffixes. Additionally ILIAS checks if the rest of the filename corresponds to filenames of video files used in the learning module.
• Again ILIAS shows a confirmation screen with all identified assignments before moving the files into the media objects.

3 Discussion

JourFixe, ILIAS [jourfixe], 13 July 2015: We support the feature request. Alex should check, if it is possible to get rid of the mediaelement.js patch, since the value added (subtitles in HTML exports) is not that big, however Chrome is one of the most used browsers nowadays. Additionally in learning modules the import features should be gathered under a new "Import" main tab. We schedule this feature for 5.1.
