I am looking for a way that I can place a handful of mixed images (JPG) and videos (AVI?, MP4?) in a directory and loop through them continuously, in full screen, creating a slideshow from the images and playing the videos. I do require the ability to add and remove files from that directory, and have the outputting show reflecting the changes. Transition effects would be nice, but are not required. A little bit of Bash or Python scripting would be fine, but I would like to avoid a full custom software.
