I have a Samsung TV which can play video files from an external USB source.
Generally this works fine, however recently I've come across some mp4 files which it says it can't play. I was a little confused at first as it can usually play mp4's without a problem but on further investigation it seems the problematic files have no video codec.
Can I 'install' this codec somehow in the file?
Edit: I've added the TV model and the file info from the video files. Unfortunately I don't own the actual footage so cannot post here.
TV model at the top, followed by the working file, then the non working file. The missing video codec is obvious.
When I try to play a non working file, I get this error message.
