IINA is simply great. It's video player that just work. The same experience when I use PotPlayer on Windows.
My experience with VLC never good. Even the modern version. It somehow feels...clunky? Some random error randomly happened. As the matter of fact, I just download the latest version and test it about 5 minutes ago on my iMac, open some video, and BAM, some weird glitch happened on my screen (like graphic card error) It disappear when I quit it though.
Yet everyone, every tech author always recommended it. Maybe I'm just unlucky? :/
