Typically is not possible. Those media files are basically just data files (e.g. like a .txt text file) so media players normally do not look for anything to execute inside them. And frankly people should avoid any media player attempting to execute random code found in media files.
Case in point, the old Windows Media Player + old .wmv files used to be able to direct people to random websites to download/execute malware. Leave it to Microsoft to somehow turn a movie file into malware https://security.stackexchange.com/questions/106188/can-a-rogue-wmv-file-hijack-windows-media-player
It’s not about a media player ‘attempting to execute random code’ - an exploit is found which lets it run a command that it shouldn’t. You used to be able to jailbreak phones by loading a .pdf file that used an exploit to gain root privileges and execute code. It wasn’t a feature of the PDF reader. It was a bug that could be exploited when a specific string of characters was entered to effectively crash the pdf reader and let it run its own code instead.
A txt could easily contain malware - any file could.
PDF is a complicated format, and the hacking vectors are often thanks to embedded javascript, or vulnerabilities in the parsing libraries.
'avi' is technically a container format, kind of like 'zip', it can contain more than video/audio.
That said, I've been pirating movies since the mid 1990's and haven't gotten hacked through a .avi/.mkv/etc. The 'bad stuff' was always in a obvious .exe/.bat or some sort of executable, but sometimes named to exploit people, eg 'foomovie.avi.exe'.
If in doubt, run your videos using mplayer on Linux and not on Windows, most of that stuff tends to target the easier to exploit and more commonly deployed systems, eg Windows.
Yesh - the huge majority of malware in relation to piracy is from people deliberately running 'setup.exe' from some untrusted source, ignoring or overriding AV warnings and then wondering what went wrong. Its not from movie files and it certainly not from movie files on Linux.
