Do some Paella updates

[owi92]

See commits.

Note that #1284 hasn't been fixed completely, which is probably due to me not realizing the extent of the problem and subsequently only talking about the captions menu in polimediaupv/paella-core#372.

For the record, these are the differences:

• paella-core: polimediaupv/paella-core@1.49.6...1.50.2
• paella-slide-plugins: polimediaupv/paella-slide-plugins@1.48.1...1.50.1
• paella-skins: polimediaupv/paella-skins@1.48.0...1.48.1

Since I'm a bit lost: what exactly is this PR trying to solve? You link this one issue that's only partially fixed (what exactly is improved over the previous version?). But I think the timeline-separators are less blurry now or sth? But yeah, if you could list all the improvements I should see, that would be great :D

Idk if I would say that this PR is "trying to solve" anything.
The updates reduce the height of the timeline separator, probably the blurryness as well. And the thing I mentioned in my top comment. I believe that's it.

[owi92]

what exactly is improved over the previous version?

The thing that I wrote about in polimediaupv/paella-core#372.

[owi92]

PS: Apparently #1047 is also fixed with this.

Edit: Ah no, it's not. I mixed this up with the background of the slides shown when hovering over the timeline.

[LukasKalbertodt]

Ok so this improves at least a few things. The timeline separators are invisible for a few frames after opening the timeline, which is weird, but not too disruptive and can be fixed later.

When/where can I test this to check with the issues I have on my "Paella list"?

PS: Happy new year!

@oas777 Happy new year.
We changed our branch structure back in November, since then you can test this and any "recently" merged PRs on https://next.tobira.opencast.org/.

Thanks, @owi92. I would summarize

• "Slide separators" are not blurry anymore and as high as the slide segment bar, in line with Slide map progress bar marks are blurry polimediaupv/paella-slide-plugins#7 and Reduce height of progress bar slide marks polimediaupv/paella-slide-plugins#8. Not sure what this means for Remove slideMapProgressBarPlugin from configOverrides in skins/opencast/theme.json polimediaupv/paella-skins#6 as it is more technical.
• Control bar not disappearing: Solved for the subtitle symbol (Playback bar doesn't hide automatically after enabling captions polimediaupv/paella-core#372) and playback rate, but persists with "Pause" (symbol or clicking the video canvass) and "Options". Should we presume these two are features? Cf. Control elements not disappearing from Paella #1284.
• Slide preview bar: Not transparent and still having other issues described at Slide preview bar should be transparent  #1047 (comment), I would strongly advocate for this feature to be deactivated by default, given also the hover-over slide preview we have. Thoughts?

Other observations:

• German help texts in the control bar (visible upon hover-over) should all start with a capital letter, i. e. "Spielen" / "Pause" and "Zu Vollbild wechseln"; "Options" should be "Einstellungen"
• Why are the presenter videos suddenly horizontal? Cf. https://next.tobira.opencast.org/!v/IwRRv4DvMtI vs. https://tinyurl.com/2cqc58hs.
• There are up to eight (8!) icons in the video canvass for a dual video, can we deactivate (some of) them by default?

Thank you for the overview, Olaf. Regarding your summary:

• I have closed Remove slideMapProgressBarPlugin from configOverrides in skins/opencast/theme.json polimediaupv/paella-skins#6, this isn't necessary anymore if you are satisfied with the current result.
• I don't think Control elements not disappearing from Paella #1284 is a feature, we might have to bring this up again with the paella devs.
• I removed the slide preview bar in Remove frame control button plugin #1310. I agree that it's not necessary.

Regarding your other observations:

• I am fairly certain that the translations need to be fixed in paella. We cannot customize them in Tobira.
• The video with the horizontal presenter video you have linked was cropped by Lukas. Other presenter videos should still have their original format.
• Let's talk about the icons in our next meeting (and let's maybe try to keep it brief). It would be nice if you can suggest some icons to discard. If there are no objections from the others, I'll see to it.
