Someone on GitHub has helped me successfully play a video, pause it and play a second video and unpause the first using Will Price's OMXPlayer-Wrapper for omxplayer. What I want to do know is expand this code to add more videos for different scenarios as a front end to an interactive program for the children in my class (I am a teacher).
The original program works fine but as soon as I copy and edit it when I try and run it I get the "no module named keyb" error.
The working code has a python2 tag '#!/usr/bin/env python2 and I was opening and saving it using IDLE 3 thinking that this was causing the issue I then tried IDLE 2 and I have the exact same issue.
Here is the edited code - all I have changed is the name and location of the video 'Buddy/wait.m4v'.
Code: Select all
#!/usr/bin/env python2
# Modified jonnyalpha code by jehutting
# See jonnyalpha's code at will price python-omxplayer-wrapper issue #90
# Original code uses gpiozero's PIR in stead of keyboard keys.
# Removed also unused camera code.
# Makes use of user longagofaraway "Allow control of multiple instances via dbus #89"
# pull request!
