 If we start MPV with the command dash dash input dash IPC dash server and give it a file name, we can then play all the files in a directory and control them by sending commands to this file using SoCat. For example, we can play the next song in the playlist. We can then also cycle play pause, pause it, unpause it. We can go back a song in the list by saying playlist previous or preve. We can also seek forward in the song by seconds. We can go forward five seconds forward five seconds or the same command with a minus we can go back five seconds. In an upcoming video, I'll show you how to use this technique to control your media using the media keys on your keyboard or remotely through a network on a mobile device.
