Does Dragon Player support MP4 on Fedora?

[Jeffrey Walton]

Hi Everyone,

I have an MP4 clip that I am trying to watch on F41. When I double
click the MP4, Dragon Player opens with two buttons: Play File and
Play Stream. (It does not show the MP4 that caused Dragon Player to
launch). I cannot seem to get the MP4 to play, even if I select Play
File and browse to the file that was previously double clicked.

This seems to be the default setup of Fedora with KDE. I did not
manually install Dragon Player or change file associations. The Fedora
docs for Dragon Player are here, but they don't have much information:
https://fedoraproject.org/wiki/User_Guide_-_Playing_Multimedia#Dragon_Player.

Is Dragon Player supposed to play MP4 files? Or is there an incorrect
file association? Or maybe something else?
