Hello. I've been trying to set up a Raspberry Pi 4 4GB for displaying a playlist of looping videos that are in 1080P. I've been using VLC and it works fantastically... That is until it freezes at roughly 30 minutes to 4 hours of looping the same videos, forcing me to Ctrl + Alt + Delete and exiting out of VLC. I've tried different output settings and tried all the recommended things online to no luck. The Raspberry Pi does have some heat sinks (on top of the hotter chips) and a fan as well to try and not get it too hot. I do understand that this forum is mostly just for Ubuntu Mate issues and not for third party software but admittedly, I've never had an issue similar to this one when I tried to use VLC on other distros or platforms. Other than that, I've had little to no problems with Ubuntu Mate.
