I have attempted to install the H.264 decoder so that I can open my Dashcam videos. I ventured into that dark and mysterious place called "Terminal".

I encountered a problem that said that my package needed to be reinstalled. It ended up that I had nothing other than the Apt-get command that won't go away.

I use Ubuntu Beaver 18.04, which I can operate reasonably well in the normal stuff but I knew I should have stayed out of the terminal.

Write your answers slowly as I am 81 and read slowly, and understand a lot slower.

to play dashcam videos .....you may like to install a media player like vlc?

try copy and paste from this tutorial

Assuming the link is still valid as I do not use Ubuntu the lines to copy and paste into your terminal are:

If you get any errors

copy and paste from your terminal into your reply so we can see where you might have issues please

Thank you for your reply, however when I finally got to 'do you want to continue Y/N I pressed Y and then the command line said abort.

I use Ubuntu Beaver 18.04

Thank you for your reply, however when I finally got to 'do you want to continue Y/N I pressed Y and then the command line said abort.

I use Ubuntu Beaver 18.04 I did copy and Paste

I now find myself in this situation: I am in the terminal and the final command line states: Sudo apt-get install ubuntu-restricted-extras

If I try to close the terminal I get: There is a process running in this terminal. Closing the terminal will kill it. )Close terminal or Cancel.)

the process was still running but I guess you did not see my reply so close the terminal is fine.

1) lets see if you have at least installed some of the dependencies to run vlc?

I will show mine so you know what to expect....I have more installed....more is better but not a problem

so pretending you get similar results......lets try a different way to get the restricted package?

ignore the release 12.04 you should see a similar image as showing in the link

ahh there is a youtube movie for 18.04

good luck

You don't need the terminal to install a standard media player on ubuntu.
And yes, the h264 codec is pretty standard nowadays and any media player should support it; VLC and mpv definitely do.
