When you have the SPK: Uninstall w KEEP option Backup Databases in case you have DB issues Install lower version Give some extra time for DB to revert to pre 1.40

Sorry, I don’t know how to download an old version. The plex web site allow only the latter version to download. How can I retrieve the 1.32.8 plex version for DSM ? Tkanks a lot for your previous fast answer.

I retrieved an old 1.32.8 version of plex. All is installed and works very well (video transcoding WITH HDR Tone Mapping) ! Thanks a lot ! For those who need an older version of PSM for Synology : axlecrusher/plex_download_urls/blob/master/archives/linux-x86_64.synology-dsm7.md # l…

So when do we get to peek under your hat? :grinning: Is there going to be an update soon resolving HDR tone mapping? I’m using an ARC A380 and at some point things broke and I didn’t realize why I was suddenly getting huge CPU spikes. Turning off tone mapping for now.

Sneak peaks always happen at the State Fair :cowboy_hat_face: We have existing CPUs we’re still ironing out problems with. As previously stated , these are priority #1. There are a couple other transcoder features which are waiting to deploy to you all. These were pushed back due to the CPU…

@ChuckPa Now with 1.40.5.8796 it seems it doesn’t even even fallback to software transcoding. The segmentation fault exits out the whole plexmediaserver, not just that one transcoding process. But yeah, I guess I’ll keep tone mapping turned off for now, just to be safe. Is there any way y’all can r…

@jakeman2048 If you want 1.40.2 then you’re free to stick with it until we do add ARC GPU support. Arc GPUs working with 1.40.2 is a fluke. We didn’t test or plan for it. Some folks just got lucky because of what’s installed already on their machines. The transcoder will not be reverted. D…

@ChuckPa Any chance you can elaborate on exactly what these tone mapping options do from the latest release? (Tone Mapping) Added a preference to select tone mapping algorithm to use. Only available on some platforms/devices. (PM-1431)

Yes, Very simple: The current default (and only) choice is Mobius tone mapping algorithm. This usually leads to over saturated colors . It almost makes the resultant H264 unwatchable. What we are adding is where you can select the algorithm you want: – Mobius – Hable (much more realisti…

Same happened to me. Revert your image to 1.40.2.
