Music doesn't play in Kodi Matrix

[wormvortex]

Since upgrading to matrix the plex-for-kodi app will not play music. Videos load fine but music just opens the player and stays at 0 seconds no matter what I try and play.

Details:

• Add-on version: latest
• Kodi version: matrix
• OS Platform: libreleec
• Hardware: pi4

It looks like the playlist data coming in is wrong?

Found a way to fix it. Not sure it is the best though. I made changes in plugin.py and player.py:

~/.kodi/addons/script.plex/plugin.py

play()
#44
-        plexObject = plexobjects.PlexObject.deSerialize(base64.urlsafe_b64decode(data))
+        plexObject = plexobjects.PlexObject.deSerialize(base64.urlsafe_b64decode(data[1:]))

~/.kodi/addons/script.plexli/player.py

extractTrackInfo()

#516
-            track = plexobjects.PlexObject.deSerialize(base64.urlsafe_b64decode(data.encode('utf-8')))
+            track = plexobjects.PlexObject.deSerialize(base64.urlsafe_b64decode(data[1:].encode('utf-8')))

createTrackListItem()

#870
-        data = base64.urlsafe_b64encode(track.serialize())
+        data = base64.urlsafe_b64encode(bytearray(track.serialize(),'utf-8'))

Hope it helps.

I have an Nvidia Shield running Kodi / Plex. Where and how would I even find these files?

@jhoms That worked PERFECTLY! Thank you. I am now able to use Plex for the first time since this summer!

I do have some questions. Why did it break in the first place? And why not put this fix in the production code?

Also, my Shield says the current version is 0.3.4, but GitHub says latest version is 0.1.6. I just want to have this work - permanently and understand what the situation is.

And thanks for responding!

[jhoms]

Why did it break in the first place?

My guess is that with Matrix upgrade some python libraries got upgraded to and they work different.

And why not put this fix in the production code?

I don't know. I was just in the same situation as you, but with my little knowledge of python found a workaround. I am glad it is working for you too.

Regarding the versions, I don't know. Maybe the people who takes care of this piece of code can. They can also make this change in the original code (even find a better fix) so future upgrades work fine out of the box.

[DarkissGit]

This solution worked for me.

Add-on version: latest (0.3.4) Kodi version: Matrix v19.3 OS Platform: Android 11.0 Hardware: Nvidia Shield

Thx @jhoms

I was trying to reproduce your problem but in my installation is working fine, so it is hard for me to find a way to fix it. Sorry.

[Kotva666]

I have the same problem which as you can see has been there since 2021 ... today I installed the new libreelec on RPi4 and the plex script on it, everything works except the music itself. Is it such a problem for the developers to care and fix this bug? When I download the Composite add-on I can play the audio in it without any problems.
