HW transcoding isn’t working smoothly with Nvidia GPU

I don’t intentionally have subtitles turned on. I do include them in the mkv when I rip the disc. I don’t re-encode anything. I put the direct rip into my library so I get the original quality when direct playing at home.

I have several titles that take a very long time or don’t play at all. When I turn off hw transcoding it all works perfect!

Just wanted to follow up and make sure I didn’t miss any test build to resolve my P5000 (and RTX 4000 before that) transcoding issue.

I turn it on every couple of updates to see if anything has changed but so far… Nothing. Still doesn’t decode most of my media. Honestly I would be happy with hw encode only at this point.

Here is my latest logs after a playback error enabling hardware transcoding (P5000).

Plex Media Server Logs_2020-05-21_18-10-25.zip (5.8 MB)

In your latest Plex Media Server.log I do not see any Job Running: Log lines that show the h264_nvenc or *_nvdec codecs being used. One thing worth noting is that Nvidia HW Transcoding does not support zero-copy on Windows (yet) It is coming but requires some other parts of Plex Media Server to be updated first.

In your logs the last transcoded playback session you did was for Fantastic Beasts and Where to Find Them (2016) Which does not have HW transcoding enabled. If you enable this and try again, what happens with that file?

That was the title that didn’t play. It just said “error” on the dashboard. It was a remote user using a Samsung TV.

I have since did some other troubleshooting. I removed the Quadro, re-enabled the ASpeed 2400 IMPI graphics, booted without the Quadro installed, then re-installed the Quadro without any monitor plugged in and it seems to be (knock on wood) working??? It takes a few seconds longer (like up to 15 seconds) to start the stream.

I’ll continue to monitor and if I see any issues I’ll immediately pull a new log.

that is a false statement that the p2000 can not decod or encode 4k hevc your full of it i have it working on my linux box right now

you must not have a driver installed correctly check that your using the latest 440.82 and you install cuda suport that should get you up and rinning

you all so need to make shure you do a clean driver wipe of your system this is all a driver issue

i can support up to 8 simultaniuse HW trans codes of 4k hevc 10 bit 4.4.4 color space with the p2000

check out the nvidia supprted matrix https://developer.nvidia.com/video-encode-decode-gpu-support-matrix

Mine started to act up again. I noticed it is usually after someone pauses and then unpauses. The stream will toggle from playing to buffering over and over.

I would be happy with just hardware encoding.

@chrisallen
Since we already have two separate check boxes, can we just separate decode and encode? One box enables decode and one box enables encode. Neither dependent on each other.
