HDR HW Tone Mapping broken...again

[bm77525-kr]

Expected Behavior

HDR Tone Mapping should still use hardware transcode

Current Behavior

When HDR tone mapping is enabled, software transcode is used

Steps to Reproduce

1.Add the /dev/dri device to the container
2.Enable HDR tone mapping
3.Play something with HDR and force it to transcode

Environment

OS: Ubuntu 20.04.1
CPU architecture: x86_64
How docker service was installed:
Official docker repo

Running Plex 1.28.1.6041 (latest tag)

4k non-HDR continues to work via hardware decode

It works when pinning the version back to version-1.28.0.5999-97678ded3

As mentioned in previous issues regarding this, the only thing that's changed is the Plex version, please report the issue to them.

Happy to, but looking at the most recent previous issue , that wasn't mentioned at all and was fix by a code change to this repo?

[j0nnymoe]

Yea that was done and one of the dependencies was pinned to a specific version. Since then the only change to the image is a Plex update.

I can confirm that this worked for me as well (Synology DS220+ w/ celeron J4025). NOTE for idiots like me: You have to pin the version using the VERSION env variable, not by changing to an older image. If you use an old image but VERSION=latest or similar, the image will update plex as soon as it starts, and you will still have the bug.

You can set the version var to docker and it won't do any updates during init

Newer public version also broke HDR Tone Mapping.
The official Plex container also have this issue

Why does this keep happening? Anyone know if the Plex team is aware of the issue?

It's just Plex being Plex

Anyone know if the Plex team is aware of the issue?

But with Plex Team it is unknown if the transcoder team is working actively on the issue

Let's just hope this is the case.
I've got the issue too. Need to revert to 1.28.0.5999-97678ded3 too.
For those who are thinking how to do it, juste set the VERSION environment variable to this number :

    environment:
      - VERSION=1.28.0.5999-97678ded3
            # docker : Let Docker handle the Plex Version, we keep our Dockerhub Endpoint up to date
            #          with the latest public builds.
            # latest : will update plex to the latest version available that you are entitled to.
            # public : will update plexpass users to the latest public version, useful for plexpass users
            #          that don't want to be on the bleeding edge but still want the latest public updates.
            # <specific-version>: will select a specific version (eg 0.9.12.4.1192-9a47d21) of plex to
            #                     install, note you cannot use this to access plexpass versions if you do not
            #                     have plexpass.

Hello,
Does the new Plex Media Server 1.28.2.6106 works correctly with hw transcode ?
I'm not upgrading for now, I wouldn't like to know 😀

For me it doesn’t solve the issue. Still doesn’t work.
