I know default video player in Ubuntu can download required codecs to play MPEG4 files.

But I wonder why they are not embed this wide using codecs by default.

Suppose a user cannot access to Internet, how would they deal with this situation?

As you said, for playing MPEG4 and many decoding , it's necessary to install its codecs.

MPEG4 and many other video and audio decoding are need to install some packages like ubuntu-restricted-extras and ubuntu-restricted-addons to play them perfectly.

Let us to look around this package:

apt show ubuntu-restricted-extras

The output has these lines in it:

These software packages are from the Multiverse channel, restricted by copyright or legal issues in some countries. For more information, see http://www.ubuntu.com/ubuntu/licensing

So as you see because of copyright or legal issues in some countries , it cannot be installed by default.

Many codecs and packages are those available in the multiverse repository of Ubuntu , that's not be enable by default, because of legal issues in some countries.

But you asked about condition that user cannot access to Internet.

In this condition the user who installed Ubuntu can check the Install third party software option during Ubuntu setup.

So many codecs are installed by default without Internet access.

  • @EsmaeelE Thanks for your reply. I said "many codecs" but not "all of them". but if you haven't access to internet you can install codec's packages offline with this method : https://askubuntu.com/questions/974/how-can-i-install-software-or-packages-without-internet-offline – Ali Razmdideh Jun 04 '17 at 12:22
