Hi all, I am brand new to Raspberry Pi but I can see it has powerful abilities. I need to setup my Pi 3 B+ and connect it to a TV as the output source and then every 15 minutes, switch the input source on the TV where the pi is connected and play a video and then switch the TV back to the original input source. Using Raspbian, I have managed to load the video mp4 file to the pi, use cron to schedule the playing of the video using omxplayer but it is glitchy. The scheduling only seems to work if I set the schedule to every minute using 5 *'s. The part that loses me is how to automatically have the TV play the video but then go back to playing live TV after the video is finished. Any and all help with this is greatly appreciated. The current setup in Cron is this: 15 * * * * omxplayer /home/pi/Videos/videofile.mp4. Thank you!
