To install the contents of these files on an ARMhf device, copy the tar archive over to the target machine and issue the following: |
|
|
|
sudo tar Cfx / $ARCHIVE_NAME |
|
|

After install of these libraries, issue the following two commands and restart Vivaldi: |
|
|
|
mkdir -p ~/.config/vivaldi/WidevineCdm |
|
echo '{"Path":"/opt/WidevineCdm"}' > ~/.config/vivaldi/WidevineCdm/latest-component-updated-widevine-cdm |

I've just tested this successfully with the latest Raspberry Pi OS (2020-08-20) and latest Vivaldi (3.3). Thank you very much! 👍
Edit:
Actually you don't need Vivaldi and can use Chromium. You just have to copy the
libwidevinecdm.sofile from the TGZ to the following folder on your Pi:/usr/lib/chromium-browser/
