inputstreamhelper downloaded wrong arch of libwidevinecdm.so?

[lameventanas]

I started the Netflix addon after a long time, and I was prompted to update libwidevinecdm, so I followed the wizard.
Once finished, I couldn't play the stream and I found this in the log file:

I checked the new library, it seems to be arm 64-bit:

On an identical system (without updating the library), it shows:

I'm running CoreELEC on an Odroid C-4

Same problem since I updated the widevine addon two days ago in Libreelec Kodi on a RapsberryPi 2 (for the Retrospect plugin).
Error log shows Failed to load library: /storage/.kodi/cdm/libwidevinecdm.so: wrong ELF class: ELFCLASS64

RaspberryPi 2 (uname -a: Linux LibreELEC 6.6.70 #1 SMP Mon Jan 20 00:43:39 UTC 2025 armv7l GNU/Linux)
Kodi 21.2 Omega
inputstream v 0.7.0

It seems to have picked the wrong ChromeOS recovery image to extract the libwidevinecdm.so lib.

There is no older version I can revert back to.

Regards,

Paul

I have the same issue.

I need the 32-bit binary, but inpustream.helper is downloading the 64-bit one by mistake.

I'm using webOS which is 32-bit OS using softfp with neon.

Same issue here.
I am running coreELEC with Kodi 21.2 on an Odroid N2 (Linux system with arm architecture).
It currently has a 64bit Widevine version, while it should be a 32bit.
Temporarily solved it as follows:
Check the image file overview: https://dl.google.com/dl/edgedl/chromeos/recovery/recovery.conf
Download the image for an Acer R13 Chromebook:
https://dl.google.com/dl/edgedl/chromeos/recovery/chromeos_15886.44.0_elm_recovery_stable-channel_mp-v6.bin.zip
The .zip file contains a .bin file. Extract this.
Open the .bin file with 7-zip file manager. It contains approx. 10 .img files. Extract:
2.ROOT-A.img
Open 2.ROOT-A.img and extract this file:
opt/google/chrome/WidevineCdm/_platform_specific/cros_arm64/libwidevinecdm.so

SSH into the Odroid device and copy this file to:
\storage.kodi\cdm\libwidevinecdm.so (overwriting the existing file)
Now reboot and test.

I found that inputstreamhelper keeps several backups. You can restore them via de Configuration option of the addon. I got an error message during the restore but after a reboot it was working again. Easiest temp solution.

Also affects me, on Raspberry Pi 4 with LibreELEC.

Also affects me, on Raspberry Pi 4 with LibreELEC.

Same here. For the temp fix I basically followed this post #589 (comment) by @koekiemonster99
An AI told me that Acer R13 Chromebook fits for the Pi4 LibreELEC as well.

In LibreELEC and when InputStream Helper is installed (which I assume people ending up here have), there is actually no need unzip several times down to the partitions and extract the lib manually.

Some more details, for those who struggled, like me (click to expand) ...

Just download the chromeos zip and bring it to your kodi device here:
> LibreELEC (official): 10.0.4 (RPi4.arm)
> Linux ... 5.10.110 #1 SMP Sat Jan 7 12:15:32 UTC 2023 aarch64 GNU/Linux

I did it directly within the my LibreELEC device (enable ssh and log on with the root user):

mkdir /storage/downloads
# I recommend to use such a 'near /'-path as the AddOn cannot access a hidden path like .kodi -
# e.g. the InputStream Helper AddOn usually stores the chromeos.zip downloads under 
#  /storage/.kodi/userdata/addon_data/script.module.inputstreamhelper/

cd /storage/downloads
wget https://dl.google.com/dl/edgedl/chromeos/recovery/chromeos_15886.44.0_elm_recovery_stable-channel_mp-v6.bin.zip

As explained you can also download on your PC and transfer the zip on whatever way to the Kodi device.

Now (via Kodi UI) -> Open the InputStream Helper AddOn Konfig.

System > AddOns > User AddOns > Program AddOns -> InputStream Helper
(open settings / konfig - don't remember the name )
Go to "Debug" and Select Install Widevine

Per default it would download and install the chromeos from the url you provided (one setting below -> so actually you can also copy in the URL and skip the whole download or transfer steps).
Anyway I had it on my device already, so choose no, when you start the install dialog.
It will then allow you, to select a zip manually. Go to '/storage/downloads' and select 'chromeos_15886.44.0_elm_recovery_stable-channel_mp-v6.bin.zip' let it install.

When it was finished, it asks for an update. Abort that!, otherwise you will get the latest non working one installed again.

I would disable the InputStream Helper AddOn for now. Also in the Apps like Disney+, Netflix, RTL+ (whatever you use and needs widewine) look for a setting to disable the widevine update/check, otherwise you will get bothered (and potentially trigger the update again), when you start the AddOn or a stream.

Remember all settings you disabled!
-> Once the issue is fixed, you want to use the automatic update
of widevine again.

The hana board uses aarch64 binaries, instead of arm binaries, see:
https://www.chromium.org/chromium-os/developer-library/reference/development/developer-information-for-chrome-os-devices/

I selected Acer Chromebook Spin 311 (Jacuzzi, arm):
https://dl.google.com/dl/edgedl/chromeos/recovery/chromeos_16267.51.0_jacuzzi_recovery_stable-channel_JacuzziMPKeys-v18.bin.zip

Same result :-(

More image versions:
https://chromiumdash.appspot.com/serving-builds?deviceCategory=ChromeOS

[pgillich]

I selected an older model: AOpen Chromebox Mini
I extracted the libwidevinecdm.so from https://dl.google.com/dl/edgedl/chromeos/recovery/chromeos_14388.61.0_veyron-fievel_recovery_stable-channel_fievel-mp.bin.zip

It works, but the version number is older.

Does Google build new images for 32-bit ARM yet?
