I’m running Anthias (latest version) on Raspberry Pi OS Lite (Bookworm), installed via the official Docker method.
My setup:
Raspberry Pi 5 connected via HDMI to a 4K TV
Issue:
Whenever there is a transition from an image to a video or from a video back to an image, the TV displays an OSD message in the top-right corner indicating an input mode switch (e.g., “VIDEOCORE 1920x1080”).
Observations:
This issue does not occur when the Raspberry Pi is connected to a native 1080p monitor or TV.
I attempted to force the resolution by adding:
video=HDMI-A-1:1920x1080@60 video=HDMI-A-2:1920x1080@60
to /boot/firmware/cmdline.txt, but it did not help.
When I force 4K resolution both in /boot/firmware/cmdline.txt and in ~/.screenly/screenly.conf, the OSD message no longer appears. However, this requires using 4K videos.
Limitation:
I cannot use 4K videos because hardware acceleration on Raspberry Pi 5 is not working properly, and playback stutters (see related issue: #2612).
Question:
Is there a way to prevent the HDMI mode switching (and the resulting OSD message) while staying at 1080p output? Any recommended configuration or workaround would be greatly appreciated.
Thank you for your help.
Best regards,
Tomasi
