i can’t get HW transcoding to work! not sure what it is i am missing here. help is truly appreciatedPlex Media Server Logs_2019-02-27_14-05-18.zip (1.8 MB)
Thanks for including the logs
They do show
Feb 27, 2019 13:09:54.788 [0x7fe4dfbef700] ERROR - [FFMPEG] - No NVENC capable devices found
Feb 27, 2019 13:09:54.788 [0x7fe4dfbef700] WARN - avcodec_open2 returned -542398533 for encoder 'h264_nvenc'
I don’t use nVidia on Linux workstations but do have it in the NAS. The nVidia GPU drivers must be on the LD_LIBRARY_PATH somewhere for it to work.
If you are doing a normal installation, they should show up in /lib or /lib64 (system defaults).
Thanks allot for your response, could you please elaborate on what it is I’m supposed to do to get Plex to recognize the drivers? (Copy or point Plex towards them) I installed the drivers the usual way through the official Nvidia PPA. Also rolled them back a couple of times to eliminate doubt. Lspci shows Nvidia properly and it’s the prime vga the system is using. nvidia-ims reports positive output.
Another note, I’m not sure if it’s important, I can’t get a video signal out of the quadro
Thx
The nvidia drivers should be on the default /lib64 and /lib LD_LIBRARY paths
If they aren’t installed there anymore, we’ll need to symlink them in.
Did you rerun ldconfig to have it update the links after installing and then reboot ?
On the QNAP boxes, which I just did this for 2 weeks ago, I appended the path to the drivers on LD_LIBRARY_PATH. This was an unusual but necessary step due to how QNAP does things. Their drivers end up in /opt
Hmmm … interesting, I didn’t ldconfig, I’ll also check the paths and will report back. Appreciate the tip.
The drivers aren’t there, Could you be kind enough to guide me symlink the drivers to lib64 and /lib LD_LIBRARY paths? I’m unable to get it done. Thanks a million
Does nvidia-smi report the card properly? Did you reboot after installing the drivers?
Example nvidia-smi output:

Edit: You should not need to do anything after installing the drivers successfully and nvdia-smi reporting the card is there. Everything should be put into the proper paths.
Thanks for the feedback, nvidia-smi reports that the device and the driver are installed properly but still no go. i also tried modifying the path as chuck suggested with
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/lib/nvidia-390"
but i still can’t seem to be able to add a symlink for the drivers to lib and lib64
any assistance would be appreciated.
Have you tried using a newer diver?
410 downloaded from nvidia says that Quadro P600 isn’t supported, detected or something similar i really can’t remember.
i attempted a clean ubuntu server 18.04 install, still not getting anywhere.
You may want to verify that the older diver works properly with 18.04.
what ChuckPA mentioned makes total sense, the driver is well installed and recognized by the system, it’s Plex that can’t seem to link to it.
i’m holding for his wisdom on how to link the drivers properly with /lib64 and /lib LD_LIBRARY
but hey! thanks allot for your input and don’t hold back if you have any other ideas.
p600 is listed as a supported device on the even the latest nvidia drivers, so if you had errors involved with a newer driver then you should probably investigate that first.

edit; sorry p600 is supported
and for what it is worth, p400 is what I have and works fine with latest driver.
i saw that and that’s why i attempted the installation but the driver installer prompt says the device is going to be ignored 
is that normal? should i bite and proceed anyway?
if there is some message the driver installer is telling you, you should probably write it down and google it.
if it says something about 32bit compatibility then that can be safely ignored if you are on a 64bit os.
I’ve been googling to my heart’s content for the past two days. although nvidia says it is compatible, the installer mentions that the Quadro P600 is supported through the legact 380.xx driver. i tried the 418 driver a few minutes ago just to confirm
no i didn’t get any 32bit compatibility issues, i’m running a 64bit system anyway.
very weird.
you might try @ https://github.com/keylase/nvidia-patch and start with the newest driver listed and go backwards.
(don’t worry about the patch itself until you can get the card working)
The drivers link back to the official nvidia repositories, I guess they are all about the patch, I’ll give the patch a shot, maybe the replacement libraries would override whatever is holding the system back. Thanks for the tip. Cheers.
the patch is not going to fix it if the driver install says it doesn’t support the card.
the patch is a very simply modification of a few bit of data related only to the encoder code. the patch does not replace any libraries, it modified a file (making a backup copy first), thats it.
what I meant by providing the link was a list of known good linux drivers.
start with the newer ones if they dont’ work, uninstall and install the next older.
or start with the oldest and go forward, either way, you should be able to see what driver starts giving you the error.
What’s bugging me is that I don’t have any issues with the card nor the latest driver supported, it is Plex that can’t seem to recognize the card or see the drivers. I have tried to install the drivers from both the Official Ubuntu PPA and direct .run file versions from the nvidia website.
Good to know how the patch works though and I’ll try the drivers they provide, fingers crossed and thanks allot once again.
