Well, i have been working all day trying to find a way to use the Le Potato as a Digital Photo Frame on a Samsung 50" 4k TV and so far any software I have tried to download and install just exhibits errors or missing libraries that I can’t seem to get installed. You all have any ideas of what I can use or point me in a direction of someone who has done this?
I had the same issue doing the same thing with a Pi Zero.
What I settled on was using Feh picture viewer to do a slideshow.
This is untested since I do not have my Potato with me here at work, but you can try the following if you are using a stock Raspbian distro.
- Install feh
sudo apt insntall feh
- If lxterminal isn’t installed install that too
sudo apt install lxterminal
- Place some pictures in
/home/slideshow/display
for testing (created the directory) - Open a terminal window and type in
feh -Y -x -q -D 10 -B black -F -Z -r 120 /home/slideshow/display
Do not touch the mouse. If this starts a slideshow you are all set. It should start the slideshow, display each picture for 10 seconds. It will rescan the directory every 120 seconds for changes, and restart the slide show if new photos have been added or removed.
If you want it to auto start you should be able to do the following on a stock raspbin install
Navigate toetc/xdg/autostart
Create a new text document in this folder and name itSlideShow.desktop
(you may need to sudo to do this)
Edit the new document with the one lineExec=lxterminal -e "feh -Y -x -q -D 10 -B black -F -Z -R 120 /home/slideshow/display"
(you may need to sudo to do this)
On boot this should start the slideshow in full screen, displaying each image for 10 seconds, and rescanning the directory every 120 seconds for new additions.
I highly recommend that you also set up wifi and set up an FTP server. Grant the FTP user access to the slideshow directory of images so you can change them whenever you want by connecting to it remotely and just adding or removing from the directory.
I use this exact method for the display in the lobby of the small business I work at, and it has been running great. Once in a while the FTP server will crash but the display continues to work.
One thing to note, any touch of a keyboard or mouse input will stop Feh and return to desktop. It is more of a screen saver than an image viewer, but it works great if the system is running with neither attached.
We recommend running weston and then a gstreamer pipeline to display the photos. You can tweak the pipeline settings and perform color transforms and such. Bare framebuffer slideshows are subject to limitations of the application in terms of color space and scaling algorithms.
