Features of Elmedia Player:

Playlist support: Elmedia will automatically add your dragged files to the current playlist. Do this by converting the playlist to an M3U file. Choose the order of the game!

Format Compatibility: If needed, Elmedia Video Player for Mac will convert your file before streaming.
4K Casting: 4K casting support in Elmedia Player is great. Get the most out of your HDTVs, Chromecast Ultra, and streaming devices like Apple TV 4K.

Playlists via Wi-Fi: Play entire albums or entire seasons of a show by selecting it from your saved playlists.
