Vivaldi (which is a nice browser overall in my opinion) did not display video on some sites.
It appeared to be codecs.
Solution with thanks to lamarca:
At install be in the directory you downloaded in!@lamarca said in Still no video on certain sites:
Your distro does not provide that package (when it's ubuntu thing). I use the archlinux herecura repo:
If you are using x86_64, download the package below:
https://repo.herecura.eu/herecura/x86_6 ... pkg.tar.xz
extract the package
install the libffmpeg.so issuing the following command:
sudo install libffmpeg.so /opt/vivaldi
After that all works fine.
