@bhepler said in Ghost Overlay / OMXPlayerTransparency: Video of the ghost in the mirror can be found here: https://youtu.be/6hb1N1tYcPc As an aside, this morning I changed the command to omxplayer -p -o local --loop --alpha 85 boo.mp4 to cut the sound from the video file. It woke me up when the mirror switched on this morning at 5 AM. Realy nice solution! Looks awesome! Could you sum up all the things needed for that? Reading through this 4 Pages is very difficulty. Would be very thankful.

Hey! Deactivate screensaver if not done yet. That may be a cause. How do you controll the display? Are you using a command like /opt/vc/nin/tvservice -o and /opt/vc/nin/tvservice -p or just tvservice -o? And is the display connected via hdmi? If that’s the case you could try the following: In /boot/config.txt add hdmi_blanking=1 and reboot. Now try HDMI Output OFF with vcgencmd display_power 0 and HDMI Output ON with vcgencmd display_power 1 instead of the command above. Descript here. :)
