Merge pull request #143 from lduarte1991/2021-03-09-new-video-ui

UI Updates for Video Annotations (VideoJS)

Live Updates

• live updates via websockets
• fixes in jwt signature checks
• hxighlighter fix in hrange for text annotations (hxighlighter v1.3.1)

Admin Hub fixes

Contains some small fixes to language in the admin hub, as well as hiding features not commonly used by the content creators to decrease complexity.

Also contains fixes to edit page for video sources, since the content disappeared in the form (though remained in the database.

Fixing Delete Annotations Bug in Text Annotations

Fixes a bug where text annotations could not be deleted once they were made because an annotation object was not passed around to the viewer.

Removing annotation length limit for instructors

v3.3.1

Updating Hxighlighter to not limit text size for instructors

UI Updates for Image Annotation (Still using Mirador 2)

• Includes new plugins for Mirador v2 in order to ensure consistency in UI across media types.
• Sidebar moved to the left and looks like in the new Text Hxighlighter UI
• Available Tags changed to Instructor tags
• A few bug fixes that are relevant for plugins used in both text and images.

Fixing Grading Issue

(Optional update if not using LTI grade passback)

If you are using the participation grading via LTI in the old UI, this update should get everything up and running again. A button was added to have user force the grade passback to the LMS via LTI. The new version is working as intended though there may be a fix later on to also add the "grade me" button.

Admin Hub Assignment Fixes

Changed type of tags property in Assignments from CharField to TextField and increased max length.
Changed wording of annotations settings from save to "continue editing" to reduce confusion amongst instructors thinking their tags were saved when they weren't.
Changed code to allow comma-separated values as tags (purely so the assignment form wouldn't break) but client-side they will NOT display correctly.

Backward Compatibility Fixes & Small UI Changes

1. Updated Hxighlighter's h-range file to forego checking global position if the variable does not exist (as it does not for annotations created before switch to WebAnnotations).
2. Added check to see if in cases where the xpath matches, but the text does not, that nonalphanumeric differences (such as extra spaces or carriage returns) are accepted as still matching.
3. Added some padding to the lower end of the previous-next button
4. Added message when editing text target objects to warn authors of the implications to any annotations that may have been made beforehand. It also disables to text and requires manual override to edit.
5. Added fix to show the proper values for video links.
