I am using 20.04 GNOME. I tried to delete VLC with aptitude, which also somehow deleted h.264 decoder required to play some videos.
So I can't play videos on my machine any more. I've downloaded everything from h.264
as sudo apt install gstreamer1.0-libav
, sudo add-apt-repository ppa: mc3man / trusty-media
. They appear as downloaded but there is no h.264
.
How do I install h.264 decoder so I can play the videos again?
sudo apt install vlc
to get current version for your Ubuntu. I would remove the Trusty (Ubuntu 14.04) PPA and try again. – WinEunuuchs2Unix Jun 08 '20 at 02:01
