pi_video_looper

An application to turn your Raspberry Pi into a dedicated looping video playback device. Can be used in art installations, fairs, theatre, events, infoscreens, advertisements etc...

Works right out of the box, but also has a lot of customisation options to make it fit your use case. See the video_looper.ini configuration file for an overview of options.

If you miss a feature just post an issue here on Github. (https://github.com/adafruit/pi_video_looper)

Currently only the Legacy version of Raspberry Pi OS Lite is supported. You can download it from here: https://www.raspberrypi.com/software/operating-systems/#raspberry-pi-os-legacy

There are also pre-compiled images available from https://videolooper.de (but they might not always contain the latest version of pi_video_looper)

Changelog

v1.0.11

• fixed skip bug with image_player
• fixed possible dependency issue

new in v1.0.10

• NEW PLAYER: "Image Player" (beta)
  Displays images in a slideshow instead of playing videos. Display duration and other options can be controlled via the "image_player" section in video_looper.ini
  All other settings, like background image, color, wait time, copy mode, keyboard shortcuts, etc. should work as expected
  Currently tested formats: jpg, gif, png (others might work also - you need to adapt the extensions setting)

new in v1.0.9

• fixed: background image is reloaded in copymode without restart

new in v1.0.8

• playlist resume option
  when enabled will resume last played file on restart
• console output now has a timestamp for easier event tracking
• Keyboard key for shutdown added ("p")

new in v1.0.7

• huge improvements to CPU utilisation with keyboard_control enabled
• better randomness for random playback

new in v1.0.6

• Support for omxplayer ALSA sound output.
  Enabled by setting sound output for omxplayer to alsa in video_looper.ini. A new config key alsa.hw_device can be used to specify a non-default output device.
• Support for ALSA hardware volume control.
  The new config keys alsa.hw_vol_file and alsa.hw_vol_control can be used to set the output device volume in a text file provided with the videos.
• The sound_vol_file functionality can now be disabled by leaving the config value empty.

new in v1.0.5

• Support for M3U playlists.
  To be enabled by specifying a playlist path in config key playlist.path. It can be absolute, or relative to the file_reader's search directories (directory: path given, usb_drive: all USB drives' root).
  Paths in the playlist can be absolute, or relative to the playlist's path.
  Playlists can include a title for each item (#EXTINF directive); see next point. If something goes wrong with the playlist (file not found etc.) it will fall back to just play all files in the file_reader directory. (enable console_output for more info)

• Support for video titles (omxplayer only).
  Can display a text on top of the videos.
  To be enabled by config key omxplayer.show_titles. Without a playlist file, titles are simply the videos' filename (without extension).
  If an M3U playlist is used, then titles come from the playlist instead.

  An easy way to create M3U files is e.g. VLC. For an example M3U file see assets/example.m3u

new in v1.0.4

• new keyboard shortcut "k"
  skips the playback of current video (if a video is set to repeat it only skips one iteration)
• new keyboard shortcut "s" stops the current playback. pressing s again starts the playback
• reworked shortcut handling

new in v1.0.3

• major new feature: copymode
  files will be copied from the usb stick to the player (with fancy progress bar)
  you can choose if the current files should be deleted beforehand (replace mode is default) or if files from the stick should be added (add mode)
  the copymode is protected with a "password" which is represented with a file on the drive (set it via the video_looper.ini for more infos see "copymode explained below"

• advanced playlist feature: add _repeat_Nx to any filename (N is a positive integer) and file will be looped that many times (additional infos see below)

• added reload.sh to restart the looper and reload the settings from the ini

new in v1.0.2:

• in directory mode the directory is now monitored; if the number of files changes the playlist is regenerated (useful if the folder is filled e.g. via a network share)
• some defaults have changed
• new option for the countdown time (default is now 5 seconds)
• new option for a wait time between videos (default is 0 seconds)
• tweaks to the install script (skip the build of hello_video by using (sudo ./install.sh no_hello_video))
• cleanup of the directory structure
• added enable.sh analogous to disable.sh
• added ntfs and exfat support for the usb drive

new in v1.0.1:

• reworked for python3
• keyboard control (quitting the player)
• option for displaying an image instead of a blank screen between videos

How to install

sudo apt-get install git
git clone https://github.com/adafruit/pi_video_looper
cd pi_video_looper
sudo ./install.sh

Default player is omxplayer. Use the no_hello_video flag to install without the hello_video player (a lot faster to install):
sudo ./install.sh no_hello_video

Features and settings

To change the settings of the video looper (e.g. random playback, copy mode, advanced features) edit the /boot/video_looper.ini file, i.e. by quitting the player with 'ESC' and logging in to the Raspberry with an attached keyboard, or remotely via ssh. Then edit the configuration file with sudo nano /boot/video_looper.ini.

Alternatively insert the SD card into your computer and edit it with your preferred text editor.

copymode explained:

By default, the looper plays any video files from a USB drive in alphabetical order. With copymode, you only need a USB drive once, to copy the video files directly onto the RPi's SD card. Once enabled in the video_looper.ini, all files from an attached USB drive are copied onto the RPi. A progress bar shows you, well, the progress of the operation.

To protect the player from unauthorised access you need to create a file on the drive called "videopi". The extension doesn't matter. This file acts as a password. (The wording of this "password" can be changed in the video_looper.ini)

You might also want to decide if new files on the drive should replace existing files or get added. "Replace" means that any existing videofiles on the RPi get deleted, and only the new files remain.
This setting can be overruled by placing a file named "replace" or "add" on the drive.
The default mode is "replace".

Note: files with the same name always get overwritten.

notable things:

• you can have one video repeated X times before playing the next by adding _repeat_Nx to the filename of a video, where N is a positive number

  • with hello_video there is no gap when a video is repeated but there is a small gap between different videos
  • with omxplayer there will also be a short gap between the repeats

• if you have only one video then omxplayer will also loop seamlessly (and with audio)

keyboard commands:

The following keyboard commands are active by default (can be disabled in the video_looper.ini):

• "ESC" - stops playback and exits video_looper
• "k" - sKip - stops the playback of current file and plays next file
• "s" - Stop/Start - stops or starts playback of current file
• "p" - Power off - stop playback and shutdown RPi

troubleshooting:

• nothing happening (screen flashes once) when in copymode and new drive is plugged in?
  • check if you have the "password file" on your drive (see copymode explained above)
• log output can be found in /var/log/supervisor/. Enable detailed logging in the video_looper.ini with console_output = true.
  Use sudo tail -f /var/log/supervisor/video_looper-stdout* and sudo tail -f /var/log/supervisor/video_looper-stderr* to view the logs.
