Enable DRM playback on Chromium/UngoogledChromium" Flatpak

enable_drm.md

Kudos

Based on this script.

I decided to put it here because it is more findeable.

Changes

This fix works on Chromium too, not just for UngoogledChromium. Thus, I have added a check that will install webdevine on chromium if found, otherwise on UngoogledChromium.

Script

#!/usr/bin/env bash

# Exit on error and forbid unset variables
set -eu

# Get latest WideVine Version by getting last line in https://dl.google.com/widevine-cdm/versions.txt
_widevine_ver="$(wget -qO- https://dl.google.com/widevine-cdm/versions.txt | tail -n1)"

# Get the architecture of the current machine
ARCH="$(uname -m)"
case "$ARCH" in
        x86_64) WIDEVINE_ARCH="x64"
                CHROMIUM_ARCH="x64"
                ;;

        *)      echo "The architecture $ARCH is not supported." >&2
                exit 1
                ;;
esac

# Download WideVine into a temporary file and use trap to delete it on exit
widevine_zip="$(mktemp)"

wget -O "$widevine_zip" "https://dl.google.com/widevine-cdm/${_widevine_ver}-linux-${WIDEVINE_ARCH}.zip"
