Video not playing in Chromium

When I try to open chromium with a website which includes a mp4 video then the video is not played. It only shows the video control.

Maybe I miss a flag for the startupcommand for chromium:

docker run --rm -it --entrypoint chromium -v /tmp:/tmp -v /var/run/dbus:/var/run/dbus --network host --security-opt seccomp:unconfined torizon/kiosk-mode-browser@sha256:72f6077e097e188e623ffda637d467ce862232cd671291ca0623acb57154bccc --test-type --allow-insecure-localhost --disable-notifications --check-for-update-interval=315360000 --start-maximized --load-extension=/chrome-extensions/chrome-virtual-keyboard --kiosk --app=http://localhost:80

Could you please help me to find a solution for the issue ?

Thanks

Greetings @ripple,

It might be the case of an unsupported/missing codec. While the video format is MP4 the video encoding can be something different. Depending on the exact encoding chromium would need to have support for this. Is this a video off the internet or is this a test video that you made?

For reference see this similar issue: Arm64v8-debian-kiosk-mode-browser does not play mp4 files - Technical Support - Toradex Community

Converting MP4 to Webm codec solved the issue!
Thank you for the answer!

Ahh perfect glad to hear Webm just works.
