Hi,
after some update last week my chromium youtube broke down. Video is loading, but black screen is forever. Firefox works well. Chromium 73.0.3683.75 (openSUSE Build) (64b). Leap15.
Everything else works fine.
Some hint, please?

Youtube videos seem to be fine in chromium here (same version). I’m not sure what is the difference between our systems.
I need to know, which package is in use in youtube playing, I have another PC desktop with same OS and repositories, there is youtube ok. I could compare them.
E.g. sample that doesnt play:
http://www.youtube.com/watch?v=9o0imRANjm0
That plays fine here. Well, I can’t stand the sound track, but apart from that it plays fine and the visuals are good. Just not my taste in music.
You might try redoing the switch to packman:
zypper dup --from packman --allow-vendor-change
to see if that helps.

It was only sample, I understand you.
I ran command you wrote, result: nothing to do
Hi
I Firefox I see vp9 and opus for codecs;
Video from first page doesnt play, but all three video samples from test page play correctly.
I :\
In statistics for experts I noticed that video in codecs avc1.4d400d (133) / mp4a.40.2 (140) works well, but video in* Codecs vp09.00.51.08.01.01.01.01 (242) / opus (251)* doesn work. Any idea, please?

What is it?
I cannot access http://opensuse-guide.org/repo/openSUSE_Leap_15.0/ .
Old unupdated repo? Maybe it is better to delete it?
I cannot visit that in a browser. But zypper, Yast etc all seem able to access it. The only package I have from there is “libdvdcss2”. Just leave it there in your repo list.

IMO
When a problem occurs, should take a moment and consider what changed on the machine.
If you suspect codecs, then the above steps can help troubleshoot,
But,
Perhaps as important… particularly on machines which were installed years ago is to verify that you’re using HTML5 to access YouTube and not Flash.
To verify,
Visit the following page with your browser
https://www.youtube.com/html5
No one should be using Flash anymore… Except for some older videos which were compiled only that way…

Sorry, I dont really know, which video I should download. I visited the page you told me https://help.vivaldi.com/article/html5-proprietary-media-on-linux/ , there are one video window that doesnt play, when I visit next page http:// HTML5 tests - video all videos on the page play very well. But I dont understand what reason is to download Vivaldi browser. Youtube used to play for me, but some time ago, after some update (I didnt remeber when exactlly) broke down.
Sorry for my ignorance. Thanks
