This is the Arch Linux implementation of proprietary's chromium-widevine

Credits for the code goes to them.

Installing Widevine on Chromium on GNU/Linux

Most distributions' package managers come with Chromium but without Widevine, a proprietary binary blob required for DRM protected content (e.g., Netflix or Spotify). Normally your only option to access DRM-protected content would be to use Google Chrome or Mozilla Firefox, but here are some alternate ways you can keep using stock Chromium.

Instructions are for Arch GNU/Linux; should work for other Arch-based distribution.

Installing Google Chrome and using its Widevine distribution

Install Google Chrome stable (beta or unstable won't work)

You will need a AUR(Arch user repository) helper to download Google Chrome like paru or yay

Skip this if you already have it.

yay -S google-chrome

Run script

The following script symlinks Google Chrome's Widevine library to Chromium's directory.

git clone https://github.com/Empyreann/chromium-widevine.git && \
	cd chromium-widevine && \
	./use-from-google-chrome.sh

Test Widevine

warning: restarts Chromium

killall -q chromium && \
	chromium ./test-widevine.html &

…Or manually:

  1. Restart Chromium. If it was already open, then go to chrome://restart.
  2. Make sure Protected Content is enabled in settings: chrome://settings/content/protectedContent.
  3. Open test-widevine.html from this cloned repo in Chromium.

…Alternatively, visit Netflix, Spotify, or $DEGENERATE_DRM_CONTENT_PROVIDER to see if it works directly.

Limitations

  • Some streaming sites refuse to run at all on Linux because the kernel does not provide access to chipset-level fencing of DRM decryption as provided by Microsoft and Apple systems.
  • These scripts assume a standard installation from Arch Linux packages. If you have installed Google Chrome or Chromium manually, you might have to edit the scripts.
  • Because we are installing files directly to /usr (as opposed to the more appropriate /usr/local), and we have to for Chromium to find Widevine, on system upgrades your package manager might clobber these files, and you will have to redo these steps.
  • These instructions only work for amd64 (64-bit x86_64) on GNU/Linux.

Installing Widevine alone without Google Chrome

Paste this into your shell:

git clone https://github.com/Empyreann/chromium-widevine.git && \
	cd chromium-widevine && \
	./use-standalone-widevine.sh && \
	killall -q chromium && \
	chromium ./test-widevine.html &

The first method using Google Chrome just copied one directory from its installation. Observe the Widevine directory in the Google Chrome distribution:

/opt/google/chrome/WidevineCdm
├── LICENSE
├── manifest.json
└── _platform_specific
    └── linux_x64
	        └── libwidevinecdm.so

We don't actually need the whole Google Chrome installation. We can recreate that tree in the Chromium directory (i.e., /usr/lib/chromium) with a standalone distribution of the Widevine shared library. Copying just libwidevinecdm.so into /usr/lib/chromium doesn't work.

Disadvantage of this method: You might have to manually re-run this script whenever Chromium updates to get the latest Widevine. The first method piggybacks Google Chrome's distribution which is assumed to be up-to-date and updated by the same package manager that updates Chromium. Use that method unless you really don't want Google Chrome on your system.
