Ungoogled Chromium Flatpak support

[InvisibleRasta]

I tried this for ungoogled chromium flatpak and it is not working. Any suggestion on how to get it working?
Also the ungoogled chromium website has a guide but not for flaptak
Thank you

I used this script and I got widevine 4.10.2710.0 in my /home/user/.var/app/io.github.ungoogled_software.ungoogled_chromium/config/chromium/WidevineCdm/and Spotify worked for me.

test-widevine.html result:

DRM stream test result:

On Ungoogled Chromium Flatpak, Version 127.0.6533.119 (Official Build, ungoogled-chromium) (64-bit)

Make sure "Sites can play protected content" in chrome://settings/content/protectedContent, close ungoogled-chromium, run the script, and check test-widevine.html

UPDATE: The latest version string fetched from dl.google.com may not be available, so try the previous or older versions. You can hard-code the version with something like:

_widevine_ver="4.10.2830.0"

The script mentioned above was removed from the ungoogled-chromium-flatpak repo. An older version that worked for me can be found here: https://github.com/ungoogled-software/ungoogled-chromium-flatpak/blob/6dc5b79cc4f84de935f4d5a1f0a9df38b59b6986/widevine-install.sh. In case the repo is ever gone, here's a copy of the 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)"
#_widevine_ver="4.10.2830.0"

# 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="$(mktemp)"
trap 'rm -f "${widevine_zip:?}"' EXIT
wget -O "$widevine_zip" "https://dl.google.com/widevine-cdm/${_widevine_ver}-linux-${WIDEVINE_ARCH}.zip"

# Install WideVine from zip file into UngoogledChromium flatpak
_install_prefix="$HOME/.var/app/io.github.ungoogled_software.ungoogled_chromium/config/chromium/WidevineCdm/${_widevine_ver}"
unzip -p "$widevine_zip" libwidevinecdm.so | install -Dm644 "/dev/stdin" "${_install_prefix}/_platform_specific/linux_$CHROMIUM_ARCH/libwidevinecdm.so"
unzip -p "$widevine_zip" manifest.json     | install  -m644 "/dev/stdin" "${_install_prefix}/manifest.json"
unzip -p "$widevine_zip" LICENSE.txt       | install  -m644 "/dev/stdin" "${_install_prefix}/LICENSE.txt"

When I run the command, I end up with a directory structure like so:

user@host:~/.var/app/io.github.ungoogled_software.ungoogled_chromium/config/chromium/WidevineCdm> tree -a
.
├── 4.10.2891.0
│   ├── LICENSE.txt
│   ├── manifest.json
│   └── _platform_specific
│       └── linux_x64
│           └── libwidevinecdm.so
└── latest-component-updated-widevine-cdm

4 directories, 4 files

At first it didn't work for me, so make sure that Ungoogled Chromium exits completely before you re-open it. I'm not sure if this helped, but I copied the contents of 4.10.2891.0 to its parent directory, and that was the first success for me. I later removed those copied files, and it continues to work, so that was probably a red herring.
