@MDAR I know why H.264 is failing for you and hope to get out a fix soon. In the mean time I can give you a work around.

If it is armhf

wget -O- https://launchpadlibrarian.net/614082413/chromium-codecs-ffmpeg-extra_103.0.5060.134-0ubuntu0.18.04.1_armhf.deb | tail -c+1157 | tar xOJ ./usr/lib/chromium-browser/libffmpeg.so > libffmpeg.so.5.3
sudo install -m755 libffmpeg.so.5.3 /opt/vivaldi/libffmpeg.so.5.3

If it is arm64

wget -O- https://launchpadlibrarian.net/614041844/chromium-codecs-ffmpeg-extra_103.0.5060.134-0ubuntu0.18.04.1_arm64.deb | tail -c+1157 | tar xOJ ./usr/lib/chromium-browser/libffmpeg.so > libffmpeg.so.5.3
sudo install -m755 libffmpeg.so.5.3 /opt/vivaldi/libffmpeg.so.5.3

Thanks @ruario

wget -O- https://launchpadlibrarian.net/614041844/chromium-codecs-ffmpeg-extra_103.0.5060.134-0ubuntu0.18.04.1_arm64.deb | tail -c+1157 | tar xOJ ./usr/lib/chromium-browser/libffmpeg.so > libffmpeg.so.5.3
sudo install -m755 libffmpeg.so.5.3 /opt/vivaldi/libffmpeg.so.5.3

That certainly works with an Odroid C4 to get the video to load and be manually played.

In chromium, there is a setting I need to adjust in order for it to AutoPlay.

Settings
Privacy
Sound = Allow

I have checked that this setting is ON in Vivaldi, but the video won't autoplay, if a websocket command is received to load and play a video.

Videos will play if I click on the Play button (as per your test page)

I'm very happy to open a port so you can access the machine I am generating the content with.

FYI
I'm trying to get this working, with Vivadli instead of Chromium

Small update.

If I start the browser in kiosk mode, it will display the video, but NOT play it.

Until

I press F11 Twice

After that, it behaves perfectly.

The only issue is that I can't automate that button press

Have you any ideas on how I can get around this?
