Video player: jet audio (alternative media player classic+ultimate decoding)

Audio player: foobar2000 (optional listening)

There are no or few advertisements, and the functions are comprehensive (many playable formats, many practical functions, and some customization). Take up as little resources as possible. The player here refers to the player in the traditional sense, which mainly plays local files, rather than the one that searches for network TV online (in fact, it is not a pure player).

For reference only.
