so its not possible to fix within cromite?

Just tried to get Widevine working with Cromite for Windows.

I followed below guide, downloaded all files as needed and placed them in a Widevine: https://chromium.woolyss.com/#widevine

Afterwards I checked via chrome://components if the Widevine plugin was installed successfully. Sadly it's missing, which means per my understanding that Cromite didn't set the right flags during compilation process to support Widevine.

My suggestion is:

• Enable the flags required to support Widevine support for future Cromite versions
• Don't include the Widevine plugin
• When the user installs the Widevine plugin via above guide, it should be recognized and enabled in Cromite
• This prevents legal issues, since Widevine is not included per default

thank you, I will look into it considering that the cdm management source code is integrated into the media code I am looking at for https://github.com/uazo/cromite/issues/710

Just tested this with Ungoogled Chromium. In case of Ungoogled Chromium the Widevine component is missing, but if the Widevine folder from an existing Chrome installation is moved to the UserData folder it's recognized by the browser and working.

The "WidevineCdm" folder has to be copied to following path: C:\Users\WindowsAdmin\AppData\Local\Chromium\User Data

Afterwards it's recognized by the browser:

I can confirm Widevine videos then started all to work, maybe Cromite could get the same implementation in future? @uazo Thanks for your fast reply and interest to this request!

[uazo]

maybe Cromite could get the same implementation in future?

only if it is proven that the decryption key of the streams is not tied to the device.
