7.1. Files, images and video

These artefacts are internal Mahara ones to display:

  • links to files that you have uploaded
  • folders that contain files
  • show images
  • embed audio and video files

new in Mahara 17.04 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.

7.1.1. 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.

Note

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.

    • My files: You see all the folders and files that you have created.
    • Group files: You see all the folders and files that you are allowed to publish.
    • Institution files: If you are an institution administrator, you will see institution folders and files.
    • Site files: If you are a site administrator, you will see all site folders and files. Otherwise, you can only see the ones that are in the folder public in the Site files.
  3. License information: You see these fields if the site administrator turned on license metadata. Additionally, if you are in an institution, your institution administrator may require you to provide a license.

    • License: Your default license is displayed. You can set your default license in your account settings. You may choose a different license for each individual artefact.
    • Licensor: If you are uploading a file that somebody else created, you can attribute the work to them here and provide their name for example.

  5. Folder path: The breadcrumbs show in which folder you are currently.

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.

firefox_preferences

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)”.
