Question

I just copy pasted this media player in python .When I am running this using the command python mediaplayer.py (mediaplayer.py is my filwename) there is no output .Can anyone tell why?

Answer 1

It is not meant to be used as you posted it.

The class needs to be instantiated, and possibly run in a main loop of some sort.

In addition, as you can see on the line import MplayerCtrl as mpc, it isn’t a stand-alone.

Please post at minimum a link to where you downloaded it.

Also, be aware it appears to be a wrapper around a real media player that implements a wxPython interface, not a full media player, so you’ll still need the actual application (I assume mplayer based on the naming) for it to do anything.
