opera and chrome with Widevine. In earlier versions this
was done by using a static version of libwidevinecdm.so inside the opera .deb file. Today this is handled dynamicly.

looking for "opera 86 widevine_cdm_component_installer" i came across a webpage https://malaysiandigest.com/how-to-enable-widevine-content-decryption-module-in-opera/ which hinted to check : opera://components

opening that url opens a page, which next immediately started updating all kind of things :

opening and updating above components will fix your streaming problems.

This has become a serious problem for Opera, Chrome and Edge, Only Firefox works correctly. The newest Opera, Chrome and Edge seem to be unable to play embed video on the local webserver using the <video> HTML5 tag. I got the following log messasges :

crashrecovery.org/:1 Unchecked runtime.lastError: Invalid color name.
crashrecovery.org/:1 Error handling response: TypeError: Cannot destructure property 'h' of 'undefined' as it is undefined.

pixel.gif:1 Failed to load resource: the server responded with a status of 404 (Not Found)

Older versions of Opera have no problem with the <video> HTML5 tag. The last working opera is opera-stable_78.0.4093.184 From opera-stable_79.0.4143.22 and higher, up and until the latest, opera-stable_82.0.4227.43, above error message occurs, where the <video> embed looks like this :

• There is no sound running this verson on ubuntu 20.04 with opera-stable 89.0.4447.71
• obviously there is sound when running google-chrome-stable 103.0.5060.134-1 on ubuntu 20.04.

This software is in some places and environments controversial.
Is it possible to add a command-line switch :

--with-feature:tiktok=off ?

It looks like the latest opera has introduced some problematic code . As a test i installed a older version of opera and chromium-codecs-ffmpeg-extra

ubuntu@ubuntu:~$ dpkg -l | grep opera-stable
ii  opera-stable                               74.0.3911.218                       amd64        Fast, secure, easy-to-use web browser
ubuntu@ubuntu:~$ dpkg -l | grep chromium
ii  chromium-codecs-ffmpeg-extra               87.0.4280.66-0ubuntu0.18.04.1       amd64        Extra ffmpeg codecs for the Chromium Browser
ubuntu@ubuntu:~$

And the same website npo.nl plays all media perfectly.

I installed opera-stable 75.0.3969.149 on Ubuntu 20.04 LTS (GNU/Linux 5.4.0-42-generic x86_64) together with chromium-codecs-ffmpeg-extra 89.0.4389.90-0ubuntu0.18.04.2 This combination of previous versions would let me play DRM video content just fine, Since April 10
i get the following error message :
DRM: KeySystem Access Denied! -- Key system access denied! Unsupported keySystem or supportedConfigurations.

More details of ubuntu system and browser :

Whenever a new opera version is availabe I do a fast check on a dutch website npo.nl, to see whether live streaming and watching old programs work. On Ubuntu 18.04 all works fine in combination with chromium-codecs-ffmpeg-extra.
Ubuntu 18.04 :
chromium-codecs-ffmpeg-extra_87.0.4280.66-0ubuntu0.18.04.1_amd64.deb
opera-stable_73.0.3856.344_amd64.deb
Ubuntu 20.04 :
chromium-codecs-ffmpeg-extra_1%3a85.0.4183.83-0ubuntu0.20.04.2_amd64.deb
opera-stable_73.0.3856.344_amd64.deb (same version)
On Ubuntu 20.04 the DRM protected video content refuses to stream and or play.

Any tips how to get the newest opera to work properly on the most recent LTS edition of Ubuntu ?
