I can't reproduce.

okiehsch commented 1 year ago

Scratch that, I can reproduce but not consistently and not always after the second video.

gorhill commented 1 year ago

~~The video plays fine once I disable Peter Lowe's and EasyPrivacy. I am trying to figure which filter(s) from these lists is the culprit.~~

I might have made a mistake, the issue is still there with those two lists disabled. Not sure what I did that made the video play.

stephenhawk8054 commented 1 year ago

These look work for me, but I'm not even sure as the symptom doesn't look like consistent for me as well

Works for me, interesting, I need to allow the amazon request for it to work on my end.

@hagezi Can you test the proposed filters on your end?

gorhill commented 1 year ago

@stephenhawk8054 Your filters work but after a long delay.

@okiehsch Your filters work without delay.

Update: if I remove the redirection ||amazon-adsystem.com/*/apstag.js$script,redirect-rule=amazon_apstag.js:5, I get no delay with @stephenhawk8054 fitlers. So this work without excpeting amazon on my side:

Hm, I tried that, removing the redirection instead of an exception, with my filters and it didn't work, I will test again.

stephenhawk8054 commented 1 year ago

@gorhill Do you need this filter?

@okiehsch version seems like doesn't need it.

Ok, after testing removing the redirection instead of allowing the request. It works because @stephenhawk8054 has the additional exception @@||cdn.lib.getjad.io/prebid/$script,domain=filmstarts.de without it you need to allow the amazon request, which is the reason I could not reproduce at first.

hagezi commented 1 year ago

Yes, it works, i think @gorhill 's soluition is the best. Thanks!

gorhill commented 1 year ago

Should we add filmstarts.de##.main-banner to avoid the annoying layout shift?

okiehsch commented 1 year ago

the annoying layout shift?

I don't see any layout shift on my end?

stephenhawk8054 commented 1 year ago

I don't see any layout shift either but ##.main-banner does look like containing only ad elements.

gorhill commented 1 year ago

Never mind, I hadn't enabled EasyList Germany.

okiehsch commented 1 year ago

Ok, @hagezi if you update the uBO-unbreak list you can remove the filters from your personal list and the videos should play fine.

stephenhawk8054 commented 1 month ago

I think this issue is obsolete now? I can't reproduce the breakage any more.
