 +To create the autostart open:
 +  $ sudo nano /etc/rc.local
  
 +and write before "exit 0" the following:
 +  printf "  \n"
 +  printf "    =============================================\n"
 +  printf "    =             MY VIDEO LOOP                 =\n"
 +  printf "    =                                           =\n"

 +  printf "    =============================================\n"
 +  printf " \n"
 +
 +If one wants to run an additional program these line should be added:
 +  # start LEDs blinking
 +  printf "start to blink an LED on GPIO 27\n"
 +  /home/pi/python/blink_02.py &
 +e.g.:
 +   $ wget http://www.dernulleffekt.de/programme/blink_02.py.tar
 +   $ tar xf blink_02.py.tar
 +   $ sudo chown root:root blink_02.py
 +   $ sudo chmod 755 blink_02.py
 +
 +And to start the omxplayer add that:
 +  # start the omxplayer
 +  printf "start the video loop\n"
 +  omxplayer /home/pi/video/myvideo.mp4 &
 +
 +To run the omxplayer in the background one has to add the "&" at the end of the line.\\
 +
 +Copy the video to /home/pi/video. It should be has to be an mp4 (H264) format.\\

 +==== all in one USB cable ====
 +
 +To power and simultaneously connect an USB hub to the Raspberry Pi Zero with just a single USB cable one needs an [[https://en.wikipedia.org/wiki/USB_On-The-Go|USB-OTG]] cable.\\
 +
 +
 +An other possibility would be this [[raspberry:pi_zero_usb-otg|Pi Zero USB-OTG Hack]].\\
