What do I do?

Answer 1

The good news is that it is relatively easy to get both playback and encoding with AV1 under Ubuntu 18.04:

1. Playback: The repository vlc will not play AV1 files but if you install the snap version you will have that capability. Run the following from a Terminal:

   sudo snap install vlc
   

   Currently this will give you vlc 3.0.8 with AV1 playback capability.

2. Encoding: There is a guide on Ask Ubuntu which will outfit a recent version of FFmpeg with the ability to encode and decode AV1 files. This is my guide and I have just tested it again comprehensively just now and it works beautifully :)

This will give pretty up to date AV1 abilities on Ubuntu 18.04, I add a screenshot of vlc with AV1 playback on my own 18.04 system (the video was one I created myself from the 'Encoding' guide above in point 2):

It all works nicely on my system and should on yours as well :)
