VLC--the orange cone--.plays just about any and all audio and video formats that i have run across, including the early RealPlayer files i have from the early 1990s. Works on Windows, Mac OS, Linux, Android, and more. Hope that helps.
I also have used scannerlive for maybe 10 years. Works ok but have some issues that the configuration you make and save suddenly dissapears and you have to redo them again and program all the streams you had to each bank.
