Sorry for the late reply. I was away for a while. Thanks for your support.
So I found out a few things but I am still having trouble:
-
I was using Ubuntu Core stable version which was the problem why I was not able to see anything on the screen. Seems that the edge version is required to get mir-kiosk and graphical snaps running.
-
I’ve installed mir-kiosk for wayland support and I can also see something on my screen when I try out mir-kiosk-apps
-
My mpv snap is here [1]
-
When executing the mpv snap “mpv-casept.mpv SampleVideo.mp4 --vo=wayland” I get the following message:
[vo/wayland/wayland] failed to connect to a wayland server: check if a wayland compositor is running Error opening/initializing the selected video_out (--vo) device. -
Executing the mpv snap with sudo gets me further and I see the first frame of the video on the screen. Afterwards no further frames are shown and in the logs the following is shown:
[vo/wayland/wayland] can't draw, back buffer is busy
Some additional information:
-
I’ve tried to build mpv with the --enable-rpi flag but I am running into:
You manually enabled the feature 'rpi', but the autodetection check failed. Failed to run './waf configure --enable-rpi' for 'mpv': Exited with code 1. Verify that the part is using the correct parameters and try again. -
Do I need to follow the approach described in https://www.raspberrypi.org/forums/viewtopic.php?t=199775 and install the GLES and EGL files from the official raspberry pi github page + change the wscript file?
I am trying further to get mpv running on rpi with Ubuntu Core but maybe you have some advices for me. Thanks.
