Installation

Install Raspberry Pi OS on your Raspberry Pi. Follow the installation guide.
Download the Video Pi package and its dependencies and transfer them to the Raspberry Pi:

video-pi

omxiv

udevil-0.4.5

On the Raspberry Pi, install the packages:

 sudo apt install ./omxiv_*.deb
 sudo apt install ./udevil_*.deb
 sudo apt install ./video-pi_*.deb

Be aware that the video-pi package installs several files in the home directory. If these files exist, they will be overwritten:

 ~/.config/autostart/video-pi-devmon.desktop
 ~/.config/pcmanfm/LXDE-pi/desktop-items-0.conf
 ~/.config/pcmanfm/LXDE-pi/pcmanfm.conf
 ~/Desktop/raspi-config.desktop

User guide

Starting Video Pi

Make sure the HDMI or S-Video cable is connected before you power on the device.
Plug in the power source.

When Video Pi finishes startup, it will show a desktop with dark background and the red Video Pi logo.

Changing video output resolution

Connect a USB mouse and keyboard.
Click the configuration icon in the top left corner of the desktop. Use the keyboard to navigate the interface. Screen resolution settings are under Advanced.

Video playback

To start playing videos, connect a USB stick with the video files. Video Pi will play all files in alphabetical order. When it finishes the last file, it will start again with the first file without any break.

When a USB stick is connected before the device starts, Video Pi will start playing the videos immediatelly after starting up (you don’t need to disconnect the USB stick and connect it again).

To play the videos in particular order, name your files with numbers or lowercase letters. Non-latin characters (with diacritics, in cyrillic etc) as well as special characters (punctuation etc) are discouraged.

Video Pi supports Full HD (1080p) video resolution.

The loop (repeat all) function cannot be turned off.

Image slideshow

You can put image files on the USB stick too (even mix video and image files). Each image will be shown for 5 seconds.

Audio output

To adjust audio volume, disconnect the USB stick and then use the blue icon on the right side of the top system panel. Right-click the icon to change whether the sound will play from HDMI or from the 3.5mm jack.

FAQ

Video playback is not smooth

Make sure your power supply is strong enough.
Try different encoding options when rendering the video. Videos transcoded in VLC with the setting Video for MPEG4 1080p TV/device are tested to play well.
Lastly, you can try overclocking your Raspberry Pi.

Changing the time between images in a slideshow

You can change the setting only by editing the files /usr/bin/video-pi-play and /usr/bin/video-pi-play-images-only.
