Text file returned as video/mp2t about file-mimeinfo HOT 1 CLOSED

Hi, thanks for opening your issue.
The problem is that the 'magic' tests are detecting your file as video/mp2t. You can check this with the --debug --all flags; the --debug provides you with more info about where the result was obtained from and the --all flag makes sure that all types of detection are used.

By default, mimetype will try to use the mimeinfo database from freedesktop, that source correctly determines the file as being 'text'. You do not have the mimeinfo database installed, you can install it on Ubuntu using apt install desktop-file-utils. It is pre-installed with most graphical desktops on Ubuntu.

The magic database, which incorrectly labels the file as video/mp2t, is not part of this Perl module; it is used by the file command. However the file command uses different heuristics before it tries to use the magic database, it uses a stat first.

I hope this helps... even if a little.
