Firefox not playing videos on Facebook

To play video, you may need to install the required video codecs.

What package am I missing?

Chromium needs to be rebuilt I guess, because it's throwing this at me:
Code: [Select]
/usr/lib/chromium/chromium: error while loading shared libraries: libavcodec.so.58: cannot open shared object file: No such file or directory

Yeah it's about latest ffmpeg update that screw many things including firefox ability to play some video formats. You'll have to downgrade ffmpeg to a previous version 2:4.4.1-1 instead of  2:5.0-3. See the announcement section about ffmpeg to see how to roll back things to work properly like before. You may have to wait till you make any updates as you can get again that borked version of ffmpeg

Same problem here.

I have  looked at the announcement, but I don´t know where to place the
                           libplacebo-4.157.0-1-x86_64.pkg.tar.zst
nor how to use it.  May I get a link to where I can learn this ?

thanks in advance !

Follow the last @nous  method when you have to edit your  /etc/pacman.conf .That method should do the trick and roll back everything as before. After editing pacman.conf you'll have to issue 'pacman -Syyuu'  (without quotes of course)

You can skip [lib32] if you didn't use it but if you use it than leave it as is bellow.

I'm having similar issues on certain sites.  Funny enough Ungoogled Chromium not only works again with the recent update, but it also plays the videos properly, so I'm not sure what's going on as mplayer and chromium didn't work at first, but firefox was just fine, and now it's the other way around.

Installing ffmpeg-compat-58 should resolve that issue with firefox.
