Note that Opera already has a user preference for disabling autoplay, see
opera:config#Multimedia
As for stopping all playing elements, that is not related to autoplay,
since to be effective it would also have to stop elements that were
started by scripts. Possible solutions here are:
1. Requiring explicit approval for all media playback, with the
possibility of remembering approval per domain.
2. Exposing a list of all media elements associated with a document to
scripts so that extensions could find and pause all media elements.
Currently this is not possible because elements can be created by scripts
and set to play without being inserted into a document, so e.g.
document.querySelector('audio,video') does not find them.
