Re-assess / rollback JS fixes for videos

[BPerlakiH]

Previously we were fixing reader side the following attributes in the content <video> html tag (for iPhones on iOS 17 only):

• enforced that poster is removed
• enforced that playsinline is added

If there's a content side way to fix this, we should remove these hacks.

Is there any issue opened somewhere (in video.JS repository?) to track the fact that this is not working properly and should be fixed upstream? I don't mind to open the issue(s) if needed, but you probably have more context + these issues should be linked here so that we know when / if the issue is fixed upstream.

It's not a video.js bug ; see #916 (comment)

[benoit74]

These issues could be "worked-around" at video.JS level because all video.JS users with an iPhone 17 have the problem.

Video.JS could probably detect that condition and remove the poster / add the playsinline ; or do I miss something?

Possibly, I think all the selection criteria are available in User-Agent and video format

Here's my UA in Kiwix 3.5.1 on macOS 14.6.1 for instance

Same on Safari

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/17.6 Safari/605.1.15

Now on affected iPhone

Mozilla/5.0 (iPhone; CPU iPhone OS 17_5_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148

And on Safari

Mozilla/5.0 (iPhone; CPU iPhone OS 17_5_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/17.5 Mobile/15E148 Safari/604.1

@benoit74 I would like to move this issue in openzim/youtube or openzim/python-scraperlib. Is that OK for you?

[benoit74]

This problem is specific to apple platforms, so I don't think it really helps to move the issue.

The real problem is in these apple platforms / readers, the scraper is producing valid HTML5 code, only apple platforms are not capable to process it correctly.

And once problem is solved in video.JS, we still need to rollback JS fixes in kiwix-apple.

What is your intention by moving this issue? (if the goal is that I work on this issue rather than @BPerlakiH, then just assign me this issue, I don't mind to work on kiwix-apple issue ^^)
