Plex - Error installing codec's

Hi, how are you? I have installed Plex with a hard drive, among the movies, audio, images, I have 4K (2160p) content with h.265 format, trueHD audio, when I tried to play some stuff of them I have problems, because Plex couldnt install the new codec that needs to play, I was reading the log files and I saw this:

As you can see, Plex couldn’t install the codec to play that file, how can I fix that?

If you want to see the complete log, check this plz:

Best Regards

PD. I have an Odroid C2 installed the last version of DiePi.

Hi Lenin,

Thanks for the report, seems a known issue with PMS < 1.5.1. The expected URL for downloading the codec from Plex server, returns a 404 (not found):

Which is strange, because our installer will install:

root@DietPi:~# dpkg -l | grep plex
ii  plexmediaserver-installer           armhf        Plex Media Server for Linux

It may be a bug, specific to the current build, available from repo, which we use to install PMS. Or, a temp issue with Plex’s website.

Not a solution, but as a possible workaround, you can disable transcoding on clients by selecting “Quality: Original”.

Hi Fourdee, thank you very much for the quick reply.
Firstly let me send you the best wishes, thanks for take your time to do this awesome distro.
About the problem in last post, it seems the page is available, the problem could be that the parameters that are sent to that page through GET or POST are incorrect.
If you go to that page you have this error:

[b]status="Release with version 584154a-1188 not found"[/b]

It seems the parameter “status” doesn’t match with any valid value.

In addition, it seems this problem could be fixed with an update of PMS.

In dev2day ( website shows the way to do an update:
Is it correct for DietPI?

Kind Regards
