I would like to know what are some safe and easy ways to play a media (in particular, video) file that I downloaded from the internet, from an untrusted source. I know that if I use an open-source media player, like VLC, one could craft the media file in such a way to exploit a vulnerability in the media player and possibly hijack my computer. Would the Windows Movies & TV app be safer than VLC in principle, since it's not open-source? Are there any media players designed with security in mind?
