Sorry if this has been asked, but Google is failing me. I'm looking for a mosaic video player that can stream a 2 x 2 grid of video given 4 different m3u8 URLs on a Mac or PC. I can't find any answers online, so I'm wondering if anyone has a good setup here that can help me.
The number 1 app is duplex iptv. Why Everybody sleeping on this app? It's for a devices except Roku because Roku hates iptv apps. It's for windows 10, Xbox one, firestick, android phone, and ios. It's a universal app. It has picture in picture, EPG, recording ability. Number 1 iptv player.
Best-player.eu has split screen and PiP which is pretty good, only on windows I think though (about £2 from Windows store, but best player I've come across)
You can install Android app OTT Navigator ( r/OttNavigator ) via the NOX Player - it supports studio mode with multiple streams at the same time.
