When I want to play video, I use forkpty() to run a vlc player .
If I use system() , it will freeze lvgl and won’t mess up the framebuffer.
But I want lvgl do some async task at background when I run vlc.
So I need a way to pause lvgl fbdev refresh task and recovery it when vlc get job done.
Is there anyone know how to do it? Many thanks.
