DD-1698 + DD-1699: 1.4-DANS-PATCH-1 video

[jo-pol]

Differences between directories v1.4 and v1.4-DANS-PATCH-1

• preview.css (max-width/height) DD-1699
• video.js (subtitles, even in draft) DD-1698
  • When a user received permission for the video but not (asked) for the vtt files, the language tags show up but don´t work
  • inline preview does not count as download, preview on separate page does count as download. This behaviour did not change but I doubt it is correct as the new page still has a download button.
  • user friendly mime type for vtt appears as "unknown" should be something like "Web Video Text Track"

  • Still has "???" where this PR now has "default" and uses first language as default if other options fail

default track

• desired languages: &locale=en from the url has precedence over preferred languages as set in the browser
• available languages extracted from "baseName.en.vtt", "baseName.de-CH.vtt" or "baseName.vtt", 'de-CH' sorted before 'de'
• per language first a full match is tried, then the main language
• when no match is found the vtt without language is used if available
• when still having no default and only one vtt is provided, that one is used

Test data

• too large: download sample_1280x720.mp4 from https://toolsfairy.com/video-test/sample-mp4-files
