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 tested as well today with Vivaldi 3.4.2066.94 and Widevine 4.10.1679.0 on a Rpi 4. Lib is loaded and DRM passes the test but Netflix deny the access with this stupid error.
As mentioned above, it's cause by the User Agent. The User Agent Switcher extension in Chrome Store are not working properly (they must be very badly coded, this is just a HTTP header 🤦)
Switching the user agent from the CLI is simpler and working fine :
