Sometime ago, I wrote a little daemon program for Raspberry Pi to continuously slide show a bunch of images. The project was intended to be commercial – utilizing Raspberry Pi with its powerful GPU and low power requirements and targeted shop owners who have full-HD monitors continuously flipping through a set of image advertisements 24-hours a week.
I have decided to release the project under public domain hence you may use it any way you like. The program uses OpenCV for image loading and hence supports all image formats that OpenCV can load. Slide show blending occurs in GPU using dispmanx APIs hence completely bypasses both the CPU and XWindow server for smooth performance.
Before you try to compile the source, make sure:
- OpenCV libraries are installed
- Understand that the program is intended to be a daemon
- Understand that the program can run without loading any display/window manager
