My console application handles the playback of different videos via the vlc player. As soon as the video changes, VLC exits full screen mode and switches back to full screen mode when the new video is loaded. This causes a short "flicker".
To prevent this behavior I want to force a blackscreen in this time. I tried to use
tvservice --off and
tvservice --preferred to toggle the blackscreen but this also cause a short "flicker".
Then I tried to use
vcgencmd display_power to turn the screen on / off which is better than the
tvservice but also cause a short "flicker".
Is there another way? I dont't need to turn the screen off. Just make it black to hide the vlc player when the video switch. Maybe set the brightness to 0? I only found a good solution for the official 7' touchscreen. There you can use
rpi_backlight which would be a perfect solution for my problem but I have a different screen.
