Quicksync Hardware Transcoding Error: 4294967279

Server Version#: 1.30.2.6563 (Linxserver.io Docker, Unraid 6.9.2)
Player Version#: Multiple (Web, Windows Desktop, Android)

I have had hardware transcoding set up with my server’s i5 -11400 for a few years now with no issues. Today I am suddenly getting the following error message (~30 seconds after starting a transcode):
Plex Desktop Client 4K Transcode Error

This does not occur all the time, but does occur every time I try to transcode 4K content and only some of the time with 1080p content. When I start trying to transcode the video playback stops, and ~30 seconds later I get the error.

From the server playback view nothing appears to be wrong. Hardware transcoding is shown and the time for the video playing continues to pass even though the screen is blank. There is about a 30 second period between when I start transcoding and the error message shows up.
Error 1

In addition I am seeing much higher CPU usage during my attempts to transcode than I normally see when hardware transcoding is working properly.

I have confirmed this happens with both remote and local connections to my server, and across windows desktop client, web client and android (which makes sense as the transcoding issue appears to be happening on the server, not client side).

I already tried uninstalling and reinstalling the plex docker but no luck. Any help is greatly appreciated.

I’m trying to hunt down a problem everyone is seeing with Hardware Trancoding related playback.

Is it possible for you to easily switch to the 1.29.2.6364-6d72b0cf6 image and retest ?

Your screenshot above looks like normal playback but having your DEBUG logs which capture the playback failure would be great. It’ll let us see what is actually happening.

Hi ChuckPa, thank you for the quick reply!

Here are my debug logs from today. Let me see if I can find a way to revert to a previous version and I’ll get back to you.

I just downgraded to version 1.29.2.6364-6d72b0cf6, problem is gone!!

Here are logs while running the older verison.

If there is anything else I can do to help troubleshoot please let me know!

@Ocman76

That’s PERFECT. thank you.

Please leave the logs there.

I’m going to be gathering up everyone’s logs.

Will do. Let me know when you’ve got what you need.

@ChuckPa Any update?

Nothing yet. I’m nursing a bad chest cold so in and out of it.
Please watch for the announcements on releases.

That’s all I can do until fully back

Many of us are finding that staying at 1.29.2.6364, until all the issues are resolved, works for what we need to stream.

Updating isn’t required nor do I see any wizz-bang new features requiring upgrades coming.

For now, I personally would prefer function over form.

Oh sorry to hear that! Hope you recover soon. Thank you for the update. I’m running 1.29.2.6364 right now with no issues so just curious.

Also getting this issue when using hardware transcoding. All working fine for now with it disabled.

Server version is 1.31.1.6733. I don’t really have the knowledge to roll back on Unraid, but if you would like logs on this version just let me know.

EDIT: Fixed for me on 1.31.1.6733-bc0674160

Still broken for me on 1.31.1.6733-bc0674160.

Confirmed still broken on the latest plex version 1.32.0.6918.

Each time I test I change the linuxserver.io docker repository to lscr.io/linuxserver/plex and the issue returns. Only setting to linuxserver/plex:1.29.2 fixes the issue.

@ChuckPa Is this issue still being worked on?

@Ocman76

You don’t have it working in Docker on Unraid.
I have PMS in Docker on Unraid and it works.

I’m using plexinc/pms-docker.
I have a problem with the LSIO - 1.32.0 image. I don’t know why; haven’t had time to dig into it. ( maybe that’s for them ? )

I’ve lost my train of thought here about where we were going.

Can you restart PMS and give me a fresh set of DEBUG logs.

I’m asking because I’ve gotten a lot smarter about the underpinnings.

I started with 1.30.0 and then did a ‘docker pull’ to upgrade it.

I just wanted to confirm that I am seeing the transcode fail issue on 1.32 as well. I’ve tested various releases as they’ve come out in recent weeks, but 1.29.2.6364-6d72b0cf6-ls146 is what I keep having to go back to.

EDIT

Just wanted to say that I switched my repo to plexinc/pms-docker and am still seeing the transcoding fail issue on v1.32.0.6918.

I can get these logs for you over the next couple of days. My server is seeing heavy usage and I hate to kick users off so I’m trying to wait for some downtime.

To clarify, you would like the debug logs from running on v1.32.0.6918 covering the transcoding failure, correct?

Correct.

I only need DEBUG server logs ZIP from the moment the PLAY button is pressed until it fails.

As soon as it fails , go download the ZIP

Here are the logs. Looks like the latest LSIO release is v1.31.0.6635-8942ba8cc because that is what I get when I pull the latest docker image. Edit: I am seeing a different Plex version listed in settings (1.32.0.6918) than in logs, I am not sure why.

Let me know if these logs have what you need to troubleshoot or if there is anything else I can help with.

That’s a server startup followed immediately by shutdown.

No playback activity in there whatsoever

  1. Settings - Server - Troubleshooting - Download Logs
  2. It will give you a ZIP file
  3. Attach that ZIP file here.

Thank you, fixed:
