@pinportal Thanks!, I should try it. The older 2018 post below, from burnout426, is very similar and it also works on Mint 20, and I haven't noticed any side effects so far:

@drpostman A little bit better directions.

Start Opera, goto, https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases/ and download the 0.31.4-linux-x64.zip file. In Opera's download dialog, click the folder icon to show the file in the file manager. Right-click it and choose "Extract here". This will give you libffmpeg.so.

Right-click in a blank spot in the file manager and choose "open as root" and type in your password. Then, right-click on libffmpeg.so and choose cut.

Then, in the file manager, browser to "/usr/lib/x86_64-linux-gnu/opera/". Right-click in a blank spot and choose to create a new folder named lib_extra. Once the folder is created, go into it, right-click on a blank spot and choose paste. You should then see libffmpeg.so there. Then, restart Opera and goto https://youtube.com/html5 to see if h.264 support is enabled for example. Then, test out some videos. On youtube, you can right-click on a video and choose "stats for nerds" to see if it's using vp9 or h.264. Or, you can try these h.264 videos to make sure they work.

You can then close the file manager.

Is there a way to constantly display the current time and date somewhere on the top 2 or 3 rows of the browser, without having to click on an extension or add-on? I use the "Date today" extension with the "badge" enabled but it only shows the time and it is barely readable. Opening the extension displays time and date perfectly but it closes as soon as you click on the page or switch tabs. Also tried Mint 20 Cinnamon's "Time and Date" applet which does continuously display everything I need perfectly but only on the Cinnamon desktop and the browser covers it. I then have to reduce the browser window height so that I can continuously see the running time on the applet, and therefore can never run the browser in full screen mode. TIA for any advice.
