I tried playing videos in movie player but only the audio could be heard. I tried playing the video with dragon player but here also only the audio could be heard.
A message box appeared showing the following message:
Python (v2.7) requires to install plugins to play media files of the following type: H.264 decoder
I tried installing the plugin but it couldn't be installed. It isn't available in the software center too. How can I get this plugin?
