fix opera's error that can not play some video files.

fix-opera.md

Error:

Opera does not play some videos and shows this error message:
"The media could not be loaded, either because the server or network failed or because the format is not supported."

Cause:

Opera has a liciensing issue. It has a libffmpeg.so library but does not works.

Solution:

There is a solution for debian based distros. Link
Opera is based on Chromium which has a working libffmpeg.so. Just replace opera's.

Tested on:

Fedora 29
Opera 58.0.3135.127
