Jriver is good media player which works on IOS, Linux and on raspPI's. However, it's not free. But you can do a lot with it and it'll play movies too. I use on Jriver on my work PC to stream lossless audio to a couple of Raspberri PIs i have around my house/work. I even have it set up for streaming over the internet for when I go away on Holiday. Best thing is about this setup is that all my playlists and ratings stay synced as I'm using just the one library on my main PC.
