Fetches the latest Linux Widevine binary so that it can be used by Vivaldi.

intro-latest-widevine.md

With the release of Vivaldi 2.2, this page is now obsolete and unmaintained. Widevine is fetched automatically on post install of our official packages. The information below and the script are left for historical reasons but will not be updated.

If you are using something newer than Vivaldi 2.2, you should not be using this script as there is simply no need. Any need you think you have for it would be a bug IMHO and thus should be logged in a bug report. Before you do so however, you should also checkout the Vivaldi help page on Widevine, on Linux

Summary

A bunch of people asked how they could use this script with pure Chromium on Ubuntu. The following is a quick guide. Though I still suggest you at least try Vivaldi. Who knows, you might like it. Worried about proprietary componants? Remember that libwidevinecdm.so is a binary blob you are taking from Chrome, so by following this guide you will have already made your distro less "pure". Also all our additions to the Chromium base are open source and our UI, while not open, is written in HTML/CSS/JS. Thus you can see exactly what we are doing (no funny business).

If you still want to run Chromium, the following explains how it is done.

Note: For ARM(hf) use this instead. Beware it requires a +2Gb download of a ChromeOS recovery image. You can actually run it on a “regular” (x86 or x86_64 Linux) PC as it will create an archive file that can be copied to the target machine.

Chromium setup

• Install the package "chromium-codecs-ffmpeg-extra" to provide H.264/MP4 support (used by videos on Netflix)—replaced with a snap in Ubuntu 19.10 onwards. After install, you need to restart Chromium. You can confirm that it is installed and working correctly by going to https://help.vivaldi.com/article/html5-proprietary-media-on-linux/ and checking that the video plays.

• Next run the script (latest-widevine.sh). This will create the file "WidevineCdm" in "/opt/google/chrome".

• Not needed on most distro : Replace the "WidevineCdm" provided by Chromium with a symlink to the file from Chrome:

sudo rm -fr /usr/lib/chromium-browser/WidevineCdm
sudo ln -fs /opt/google/chrome/WidevineCdm /usr/lib/chromium-browser/WidevineCdm 

Note: The path is typically "/usr/lib64/chromium/WidevineCdm" on non Debian/Ubuntu based distros.

• You can confirm that DRM'd H.264/MP4 content is now playable by going to https://bitmovin.com/demos/drm and see that the DRM video is played.

Damn you Netflix!

The final complication is that Netflix does not expect pure Chromium to be able to be able play videos and hence they do a stupid thing. If they detect that Chromium is accesing a video, they point you to install Silverlight! This is particularly dumb because: you are running Linux (no Silverlight); Silverlight is an NPAPI plugin and Chrom(e|ium) only supports PPAPI. You will need to work around this.

• Delete any cookies or data associated with Netflix. If you have failed to play videos once, then Netflix stores information about this in a cookie and you won't be able to play vidoes, even once your system is now correctly configured. Another "WTF‽" moment from the Netflix team.

• Via a user agent editing extention or by starting Chromium with the -user-agent switch, remove the reference to "Ubuntu Chromium/XX.0.XXXX.XX", e.g.

/usr/lib/chromium-browser/chromium-browser --user-agent='Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.99 Safari/537.36'

Note: An extenstion is best otherwise you will need to start Chromium from the command line every time or edit the .desktop file to include this switch.

One final point. Every time Chromium upgrades it will replace the WidevineCdm symlink with its own file. Thus you will need to remove it and re-create the symlink. I would also suggest re-running latest-widevine.sh at that point, to check for new versions and upgrade if needed.

Chromium 79 ( as chrome ) needs 4.10.1610.0 but widevine website returns latest is 4.10.1582.2

So we cannot rely on

https://dl.google.com/widevine-cdm/versions.txt

to know the latest and extract it.

We have to grep the version from widevine-check-version.sh

79 does not need 4.10.1610.0. It runs absolutely fine with 4.10.1582.2. Google often give themselves a newer version than what they publish for third parties to use but as of right now 4.10.1582.2 works on every site I have tested

Correct, the same is true for ARM-based images for Chromebooks. In most (if not all) cases it is important to have a recent version that is still supported. See https://www.widevine.com/news

Yeah for Vivaldi ARM users we still have to extract from ChromeOS as there is no normal public source outside of this

https://gist.github.com/ruario/19a28d98d29d34ec9b184c42e5f8bf29

Sorry my mistake then.

Also , mozilla supply an alternative to get binaries :

https://hg.mozilla.org/releases/mozilla-beta/log/default/toolkit/content/gmp-sources/widevinecdm.json

@freechelmi Vivaldi also fetches those automatically on all the same platforms as Firefox. If you use Vivaldi on desktop you get them fetched and installed by default. That is the reason this script is not really maintained much by me anymore. Vivaldi does not need it.

@freechelmi Also Firefox almost certainly updates their json based on reading https://dl.google.com/widevine-cdm/versions.txt. So it is not really any kind of alternative.

Thanks

I try to maintain this script for chromium users

OK I understand why the script does not work.
the widevine plugin does not get loaded of the licence file and manifest are not present.
Il will update the script on my fork to add those files.

@freechelmi: Thanks, I updated it

Thanks @ruario ! That really simplify the code .

I see that you remove the netflix warning but here netflix still redirect to https://help.netflix.com/fr/node/23742 with chromium user agent .

I saw that vivaldi was smarter by including the chrome UA

@freechelmi: Ah, ok! I have now undone that change to the intro.

Yes, I took the opportunity to simplify it a little as a lot of the old code related to extraction was from before I realised I could just use python. Really no need for so many fallbacks given you would be hard pushed to find a Linux distro suitable for Vivaldi that does not also include python.

@freechelmi: I'm guessing (but have not tested because I don't have a machine to verify to hand), that it should now be possible to install and configure this for Chromium, without the need for admin privileges.

Run the script like so to install into your user directory:

WIDEVINE_INSTALL_DIR="$HOME/.local/lib/WidevineCdm" ./latest-widevine.sh

Create the Widevine configuration directory (if not already present):

mkdir -p "${XDG_CONFIG_HOME:-$HOME/.config}/chromium/WidevineCdm"

Create or update the json config file to point at your new, single user install of Widevine

echo "{\"Path\":\"$HOME/.local/lib/WidevineCdm\"}" > "${XDG_CONFIG_HOME:-$HOME/.config}/chromium/WidevineCdm/latest-component-updated-widevine-cdm"

Load demo.castlabs.com and attempt to play the videos that are tagged with “DRM”.

@ruario works fantastically. I was searching for an hour to find a proper solution, and nothing worked except this exhaustive guide.
The only thing I did different (because I didn't scroll down far enough to find the latest-widevine.sh script) is I used this instead (which probably results in the same thing):

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
dpkg -x google-chrome-stable_current_amd64.deb .
sudo cp -r ./opt/google/chrome/WidevineCdm /usr/lib/chromium-browser/

Thanks!
