These artefacts are internal Mahara ones to display:

If you are on a mobile device and select to upload a file, you can take a photo or make a video or audio recording (Android only for audio) directly.

4.2.1.1. Embedded media

Display an embedded video or audio file from your uploaded files. Mahara comes with the Video.js media player that allows for the display of a number of file formats without having another player installed on the device.

Bemerkung

The site administrator must allow media formats. Some of them can be displayed directly within Mahara while others need additional software installed on a device. See the list of allowed media formats.

Videos placed onto a page in this block scale to the width of their column. They also scale automatically when your browser space gets smaller.

Only the files that you are allowed to embed are displayed. If you uploaded a mp4 file but it does not show here, you may have to check if it has the correct codec. Only H.264 mp4 files can be embedded.

iOS devices can even be trickier as these devices may only recognize the MPEG4 ‚Baseline‘ profile rather than the ‚High‘ profile. You can read the Apple specifications and convert a video if needed using Handbrake. Newer iOS devices (from the iPhone 5S on) should play ‚High‘ profile videos.

If you have trouble embedding a PDF file, you might have come across an issue that others have also experienced. The mimetype of the PDF may not be recognized correctly. The correct ‚mimetype‘ is ‚pdf‘, but programmes can circumvent using this mimetype for PDFs to ensure that their file is downloaded instead of viewed in the browser for example. There is not an easy fix to this issue, and the discussion of possible solutions has started.

In the meantime, you can delete the incorrect mimetypes from your browser and ensure that only ‚PDF‘ is left.

Follow these steps to delete the incorrect mimetypes:

  1. Close Firefox.

  2. Locate your profile folder.

  3. Open the mimeTypes.rdf file in a text editor.

  4. Search for pdf.

  5. Leave only the entry that is application/pdf.

  6. Delete all other PDF references by deleting everything for that entry from <RDF:Description ...> to </RDF:Description>.

  7. Open Firefox and go to Preferences → Applications.

  8. Search for pdf. You should now only see one entry that reads ‚Portable Document Format (PDF)‘.
