Hi @NPal.2​ ,

You can use gstreamer framework. ( gst-launch command )

See old post : How to run BMP files using Linux yocto on STM32MP157C-DK2 board

Wiki : https://wiki.st.com/stm32mpu/wiki/GStreamer_overview

You have also an example in Starter package / Demo launcher.

The AI demo is displaying a picture on demand by doing :

"gst-launch-1.0 filesrc location=/usr/local/demo/media/stm32cubeai.png ! pngdec ! videoconvert ! imagefreeze ! waylandsink &"

See on target : /usr/local/demo/bin/apps_launcher_example.sh

THanks for answer @PatrickF​ . The information on the page was really helpful. But is there a way i can display image on screen, as full screen? Wasn't able to get that anywhere.

Hi,

I'm not specialist, and I'm not sure it is available on proposed examples.

weston-image is just for demo and show a 'window' image you can resize using mouse (you can try connecting a mouse to the DK2).

Otherwise please see https://wiki.st.com/stm32mpu/wiki/Wayland_Weston_overview#To_go_further

There is plenty of way to use the screen (see for instance GTK demo launcher, started with /usr/local/demo/demo_launcher.py)
