EAC3 Audio - License has expired

[llajas]

Describe the bug Hi! Thanks for the work on this project. Recently it was brought to my attention that multiple streams were failing on transcode. I was able to test and reproduce the issue and noticed that it only occurred on transcoded media with EAC3 encoded Dolby audio. Upon closer look at the worker logs, I noticed a message pointing towards a license expiration:

Received task request

This ultimately results in the following error:

After digging through the repo, I saw that there was a prior issue which is the same as what is described here - 'https://github.com/pabloromeo/clusterplex/issues/244'.

While I understand the bash scripting here at play, I unfortunately don't know where to obtain the latest version of the EAE to submit a pull request to update the hardcoded value for testing.

To Reproduce Steps to reproduce the behavior:

1. Attempt to play any media with Dolby EAC3 audio encoding
2. Player receives an error when attempting to transcode (Direct play/stream works fine, as expected).

Expected behavior Media plays and dispatches the transcode job to a worker pod with the applicable and up-to-date codec.

Screenshots N/A

Desktop (please complete the following information):

• OS: Fedora Server
• Version: 38

Additional context As mentioned, this seems to be a duplicate of 'https://github.com/pabloromeo/clusterplex/issues/244'. I'm more than happy to submit a PR if there is a known source for the latest EAE codec release (Although I'm sure given the bash script that there have been prior attempts at automating this 🙂 ). I don't think it matters, but my deployment is through ArgoCD/Helm and is in REMOTE only mode to dispatch the jobs to worker nodes equipped w/ a Nvidia GPU. Let me know if any other details are required here for debugging. Happy to provide what I have.

Good catch! I'll try to update to a more recent version ASAP. Unfortunately no, there is no official source that can be tracked, so it's a bit of trial and error and seeing which version gets installed by a standalone Plex install at the moment.

[pabloromeo]

Try the latest version: https://github.com/pabloromeo/clusterplex/releases/tag/v1.4.10

EAE has been updated to version 2001.

@pabloromeo works like a charm after updating. Thank you! 🍻
