Opera displays black videos on webpages such as Youtube

Hi! I'd like to ask for help.

I have problem with Opera, Youtube and playing videos. I have installed opera-ffmpeg-codecs, i have installed flash plugin for opera such as pepper-flash but i'm not able to play videos on Youtube. I hear sound but there is no video. Strange is that when video is embbed into, for an example, Facebook, i can play it without problem but switching to Youtube webpages gives me sound without video but only with black screen.

I'm not able to past debug from played video because there is black screen and no option when there is black screen instead of played movie. Could somebody help? It is only under Youtube. Can play other webpages with videos. Firefox show all correctly, no problem found.

The only way to play videos on youtube with Opera is to constantly hitting refresh key F5 and sometimes it works, but for 10 tries not even one sometimes could be successflul. I have to hit refresh key for several times, for several minutes. Coud something be done with it?

Thanks.

Terminal output? going on a limb and saying likely broken shader cache, does opening an incognito/private mode window work? Find out operas equivalent of https://bbs.archlinux.org/viewtopic.php … 2#p1650542

Could you point me how to run some youtube vid via terminal in order to see log/outputs of errors?

I'll try to delete Opera cache, but i did it via option in Opera webprowser several times.

Edit: i deleted ~/.cache/opera/Cache and ~/.cache/opera/Media Cache/ and still, black screen, cant watch - i have to constantly hit refresh key but it barely works, in fact, does not at all.

Re: Opera displays black videos on webpages such as Youtube

Ok, i tried it, i tried to watch, for an example, this vid:

https://www.youtube.com/watch?v=m871A_2aNeg

With opera under terminal, i could watch this move. When i closed it, launched normally, i had black screen with sound. On both tries i was not logged into youtube accound. Here is what the output looks like:

firekage@7500_uATX mnt]$ opera

[0108/010824.840338:ERROR:kwallet_dbus.cc(72)] Error contacting klauncher to start kwalletd5

Nothing more.

Than i closed terminal, launched again it via terminal, with the same movie and...yeah, even under terminal i could not watch this vid. It is totally random.

Here is the output again

Re: Opera displays black videos on webpages such as Youtube

I installed Opera HTML5 UNBLOCKER add-on. Now i see that all movies are launched correctly when browsing Youtube. This add-on adds support for webm format. I read that it could be problem with native bult in HMTL5 player into Opera. Don't know how to disable it, but i see that Opera supports all formats according to this:

https://www.youtube.com/html5?gl=BR&hl=pt

HTMLVideoElement
H.264
WebM VP8
Media Source Extensions
MSE & H.264
MSE & WebM VP9

and according to it, i use HTML5 player when it is possible. Maybe, like somebody wrote, it is problem with native bult in into Opera HTML5 player because with HTML5 UNBLOCKER that supports webm i can watch it. Will test again and see if it really helped.
