@xzero said in [Solved]Solving the problem of the Opera browser with video playback in Ubuntu and similar distributions (Linux Mint, KDE neon):

Can confirm this solved the issue for me.
I figured out how to use snap library, as @mr-matt-eastwood suggested.

On Manjaro Linux 20, opera directory is /usr/lib/opera.
You don't have to delete original libffmpeg.so file, but just rename it to whatever (including extension).

Steps:

# If you cannot use sudo -i, then just prefix your commands with sudo
sudo -i 
# Close your browser by hand. Following command will ensure no Opera processes are running in the background
killall opera
cd /usr/lib/opera
# Some software automatically loads any .so/.dll file that is present. Not sure for Opera, but just in case
mv libffmpeg.so libffmpeg.so_original
snap install chromium-ffmpeg
# Please note that chromium-ffmpeg-95241 path might differ. Just pickup one with highest number. 
ln -sf /snap/chromium-ffmpeg/current/chromium-ffmpeg-95241/chromium-ffmpeg/libffmpeg.so libffmpeg.so

Works like charm.

This worked like charm. Only change I noticed is opera path: /usr/lib/x86_64-linux-gnu/opera for version 100.0.4815.76
