Running the latest beta (1.41.4.9399) , I don’t see the HEVC options for transcoding.
What am I doing wrong?
NAS: Syno DS1621xs+
GPU: Nvidia T1000
Server Version#: Version 1.41.4.9399
Player Version#: iOS
How do you fit a T1000 in that Syno? Sideways?
Also , Did you patch DSM to accept and load the Nvidia drivers ?
It fits. I made a whole separate post about that a while back with instructions.
I used the hacked Pdbear nvidia drivers. Works amazing with Plex
Not so much for HEVC encoding though
What do your logs show about the HEVC capability test (when it probes ) ?
As for using the Beta 1.41.4, it has issues. Recommend going back to 1.41.3
Cant test unfortunately. There is no box to check for HEVC in the transcoder settings to enable it
I’m checking with Chris.
He’ll know if/where/how that should work in a Syno.
I think it should but he might have flags for the available drivers
if there are no Nvidia HEVC drivers referenced in PMS for Syno SPK then it won’t know what to do with it.
Thank you!
Do you see your gpu in the dropown in transcoder configurations?
@ChuckPa ill check tomorrow. I dont have access to the NAS right now
@chris_decker08 The dropdown is there but «any» is the only option
That explains why hevc is unavailable, we are unable to identify your gpu
Yea. I believe this is due to me patching the drivers to allow unlimited concurrent transcodes.
Is there any way around this? Any way to force these checkboxes to appear, Even when the card isnt detected?
If you can’t identify the card then you don’t know :
- How much memory it has
- If it has HEVC capability or not (or other codecs)
- Maximum bit depth (8, 10, or 12)
- Encodind support: 4:2:0, 4:2:2, or 4:4:4 (to name a few)
Without that info, you don’t know how to decode or encode.
There is unfortunately no “trust me” here. It must know what it’s dealing with because there is no software fallback like there is for H264.
Well I can identify the card.
Plex cant. So how about allowing users to manually select their card from the pulldown, rather than have Plex detect it?
Would that be possible?
That would require users know how to manually configure all the drivers.
You know how crazy that would be to support?
There are enough problems with docker containers and GPUs . lol
I think the better path here is to find out what’s wrong with the driver even if that means starting with the 2-transcode limited original and being more careful when patching it. 
Yea I get that
Ill revisit this once the feature is no longer labled experimental
Thanks for the help so far! To the both of you!
I don’t think there is anything wrong with my drivers. A nvidia-smi command returns this
Just to double check, I fired up Emby. It to finds the card just fine
Could it be that you guys are simply not looking for a discrete GPU in the Synology package, as there is no official support from Synology?
can you please restart your PMS instance and then send me your logs so I can see what exactly we are discovering GPU wise?
Sure. Is this the correct one?
Plex Media Server.log (876.2 KB)
that was indeed the correct one. On linux we currently use libdrm to discover GPUs with a handful of fallback options if we can’t identify anything. can you send me logs that include a playback so i can see which fallback is working for you?
