Add Youtube/Vimeo/... videos in the ZIM

[benoit74]

Libretexts rely on Youtube /Vimeo/... videos at some places, either "inline" with an <iframe> or "external" with an <a> external link which opens the video in another tab / window.

Sample pages:

• Youtube external link and iframe (both case on same page):
  • https://geo.libretexts.org/Courses/University_of_California_Davis/GEL_109:_Sediments_and_Strata_(Sumner)/09:_Draft_Textbook/9.05:_Sediment_Transport
  • page ID 10733
  • see "Sumnerd’s Sed Transport Playlist" link for the external link
• Vimeo external link:
  • 4 videos on same page
  • https://geo.libretexts.org/Courses/Diablo_Valley_College/OCEAN-101:_Fundamentals_of_Oceanography_(Keddy)/18:_Coral_Reefs/18.04:_Symbiotic_Relationships_in_Coral_Reef_Ecosystem
  • page ID 13079
  • see e.g. "Dangerous dining" link
• Vimeo iframe:
  • https://geo.libretexts.org/Courses/Gettysburg_College/Book:_An_Introduction_to_Geology_(Johnson_Affolter_Inkenbrandt_and_Mosher)/03:_Crustal_Deformation_and_Earthquakes/3.06:_Earthquake_Essentials
  • page ID 11212
  • see "2011 Tohoku Earthquake, Mag. 9.0. Body and Surface Waves from seismicsoundlab on Vimeo"

We need to :

• download, reencode, cache on S3 these videos
• add these reencoded videos to the ZIM
• fix HTML code to use video.JS plugin to display these reencoded videos
  • in-place when an <iframe> was used
  • in a popup when an <a> was used

But first (@kelson42 @Popolechien @rgaudin ):

• do we really want / need to include all these videos in the ZIM? (I suspect this can make the ZIM quite big)
• do we want to build different flavors? (no video at all, only inline videos, all videos?)

Other question: is this something required for libretexts project? I'm quite sure we never discussed this, so maybe this is simply out of scope for now and we should just drop iframe and replace them with an external link.

Flavours: no.
Including them: well yes, I assume they're part of the teaching material. Also Vimeo has been nagging us for a while, might as well seize the occasion.

I had a look at only few videos and they are more "resources" for the ones who want to dig a bit rather than essential learning material. From my PoV, they are part of the teaching material just like all other external links, which we do not include. So your argument seems a bit weak in my PoV.

Also Vimeo has been nagging us for a while, might as well seize the occasion.

Unfortunately work on supporting Vimeo here will not help supporting Vimeo in zimit, if this is what you are referring to.

Ok let me ask the client just to confirm.

Ok here is their answer:

Scraping videos is nice, but there are clear intellectual property issues here. Youtube may host Creative Commons openly licensed videos or may use a YouTube License (https://www.termsfeed.com/blog/youtube-license-types/). The latter doesn't allow for reuse permissions that scrapping represents. So, only Creative Commons videos can be legally scrapped and distributed via your infrastructure.
So, to scrap a video, you would have to use the YouTube API to query its license (I presume there is an endpoint for this) before scraping. If it is a Creative Commons license, I am game with scraping. If YouTube license, then the best we can do is substitute a hyperlink to the video (or keep it as a hyperlink).

Not sure we can ask the Youtube API for the license, so the answer at this stage is "no videos"

OK, thank you. I will postpone this issue to "later" since we might never implement this. I've opened a dedicated issue for the addition of videos in the ZIM.
