App running with platform eglfs. Although I got the right image from function QQuickWindow::grabWindow(). but It cost seconds. I actually hope cost less than 100 milliseconds
Is there a device like /dev/fb0, I can read it directly?
By the way, my qt is version is 5.9.6. CPU is ti's am3354,working with GPU. My lcd is 1280X800 pixel. kernel version is 4.14.67.
This problem has been bothering me for a long time. Does anyone know how to do?
