When I try to watch mp4 videos they play with no problem at first, but after a while of watching a couple videos they load, but I can't play them with motion and its stuck on pause even when the play symbol is on, I can skip through the video parts to see pictures of the video though but it doesn't play. I'm using lubuntu and my kernel is Linux Roedelius 4.15.0-20-generic #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux, ubuntu 18.04 bionic
I'd appreciate any help with this. This has only been happening recently after an update.
