Xbmc: no playback possible on ARM devices (License update not successful)

Hi
Same issue here - however, the logs show:

I also have the same Problem.
At yesterday the Plugin worked properply

Updating Widevine library solved this for me on LibreELEC (community): 8.90.2 (S905.arm) with KODI Leia 18.0-ALPHA1 Git:4e01f3d.

Script to extract updated widevine library from Chromebook recovery image:

#!/bin/bash
curl -s https://dl.google.com/dl/edgedl/chromeos/recovery/recovery.conf | grep -A 12 'Acer Chromebook R13' | grep -o 'https.*' | xargs curl | zcat > /tmp/image.bin
mkdir /tmp/chromeos
MOUNTCMD=$(fdisk -l /tmp/image.bin 2> /dev/null | grep 'bin3 ' | awk '{print "mount -o loop,ro,offset="$2*512" /tmp/image.bin /tmp/chromeos"}')
echo $MOUNTCMD
$(sudo $MOUNTCMD)
cp /tmp/chromeos/opt/google/chrome/libwidevinecdm*.so .
sudo umount /tmp/chromeos
rmdir /tmp/chromeos
rm /tmp/image.bin

Note: This script does not run on LibreELEC. I used Ubuntu to extract the files and copied them to LibreELEC into folder ~/.kodi/cdm/:

LibreELEC:~ # ls -l ~/.kodi/cdm/l*
-rwxr-xr-x    1 root     root       7440588 Jan 18 13:14 /storage/.kodi/cdm/libwidevinecdm.so
-rwxr-xr-x    1 root     root       5122508 Jan 18 12:26 /storage/.kodi/cdm/libwidevinecdm.so.lastused
-rwxr-xr-x    1 root     root         67700 Jan 18 13:14 /storage/.kodi/cdm/libwidevinecdmadapter.so

Those .so do not work on the Rpi3 & LE (just to spare time should someone else feel tempted to try).
Also tried the .so from a Samsung image from the same forum thread, no go, it just crashes LE.

That's actually a common issue on ARM devices with old widevine library.
I've added the inputstream helper script with commit 5a59d53ef5276be0a980fef369f63b27f4352d94, which should download and install the newest library automatically (it does the same like the script, which @jbond47 posted above).
But it didn't work on RPi's at the moment on all other ARM devices it should working.

Thank you Sandmann,
Sorry to ask but do you mean "But it [still] doesn't work on RPi's at the moment.."

If so, then it sounds like RPi's are not the best platform for this job. ;-/

Until last week it worked for RPi's running Libreelec 9 Millhouse Builds. Then changed Amazon anything, so we had to update the widevine library to a newer version. And this version doesn't work for now.

But the Kodi devs working on a solution.

Super. Wir warten gespannt !
(ps: My German is just good enough to follow the kodinerds.net thread and get 99% of it, but sometimes miss key detail ;-) )

@RobbesU could you point me towards that kodinerds thread.

(German is my mothers-tongue. So feel free to ask me about that 1% ;) )

thx!

Starting with Milhouse LE Build 207 this issue has been fixed for Rpi

Super. (Having followed kodinerds.net it looks like it wasn't all that straightforward)
Danke!
