I would like to present images and videos from one folder in Ubuntu just the way one is familiar with from smart phones/tablets.
Perfect would be if the The GNOME image viewer would be able to include videos with the most common formats with a still image into its preview/slideshow and would play them with a button-hit or mouse click. So the idea is to have images and videos in the same slideshow/fullscreen-view as in Android or iOS MediaViewers.
I found Slideshow and video application but this predetermines the duration a image is shown. I would like to present the next image/video in the folder manually (also in fullscreen) and would like to start video-playback manually as well.
