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).
# 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.
