HW Transcoding not working anymore (Synology Diskstation)

Plex Media Server NAS & Devices
21

I updated my DS916+ to Plex Server 1.18.3.2156 and I think things improved.

HEVC (H.265) HW transcoding to H.264 seems to work again. The deduce that from the fact that the CPU load of the DS (server) is low altough the player can only handle H.264. Also the log output hints that is really HW transcoding: TPU: hardware transcoding: final decoder: vaapi, final encoder: vaapi

HEVC 10bit HW transcoding does not work. The CPU load on the DiskStation is high and the video is playing, pausing, playing, pausing, … Also the server log shows that it does not do HW decode: TPU: hardware transcoding: final decoder: , final encoder: vaapi (note that the final decoder is left empty)

But I do not know whether HVEC 10bit ever worked or if the CPU is able to do that. Maybe that’s where the HW capability discussion from above meets in the middle and everybody is right. :slight_smile: :peace_symbol:

In the server log one can still see that there are still issues loading the iHD_drv_video.so library.

This is the output when playing a HVEC (8bit) file:

What does it mean that the Plex server tries to load libcuda.so.1? To me knowledge CUDA is only available on platforms with Nvidia chips.

22

  1. The N3710 CPU does not have HEVC capability . Goldmont (ApolloLake) is required to decode HEVC . The N3710 is Airmont microarchitecture.

  2. What you’re seeing in the logs is the transcoder searching for anything it can use.

23

Thanks! This fixed my problem. In particular, using the current version of Plex server 1.18.3.2156 on a Synology 1019+ to play back my blu-ray collection at 1080p, I observed the following:

  1. Just playing the h264 in mp4 embedded file plays fine with minimal CPU impact.
  2. Adding a Vobsub subtitle, which the player does not support, requires transcoding and results in either a completely scrambled image (with hardware transcoding enabled) or pegs the CPU at 100% and stutters ocasionally without hardware encoding.
  3. Moving that pesky iHD_drv_video.so somewhere Plex won’t find it and restarting the server appears to have done the trick.
  4. Transcoded movies with vobsub subtitles now play fine with only about 37% CPU load (which I can live with, though I hoped for something better given the specs).
24

To update everyone,

The problem with the iHD has been found. A new preview release is available.
It should only contain the iHD_drv_video.so correction.

(Linux desktop users got a small present too :wink: )

If there are still issues, please continue to delete the driver and we’ll address when everyone is back.

This release does not work well!
NAS = 918+
Client : Android Phone, Galaxy S7

I have the same garbled output when transcoding.

Let’s wait for some feedback from other users claiming all is fixed now.

Then I re-installed my previous version 18.0.1944 and all is good again…

Same here, transcoding doesn’t work with the new version either.

Please be specific about which version of which?

28

Basically every version since 18.0.1944 has issue. I tried yesterday link below

https://artifacts.plex.tv/plex-media-server-experimental/1.18.3.2175-4593fabed/synology/PlexMediaServer-1.18.3.2175-4593fabed-x86_64.spk

I also installed the version that my PMS suggested on login on the web-interface, 1.18.4.2171 with no luck, same transcoding garbage on start.

Reverting to my trusty 1.18.0.1944 fixes things.

Same for me. Hardware encoding do not work with my DS918+ and updated Plex Server to version 1.18.4.2171 still only retracts when playing back video with the hardwire transcoding turned on.

If I turn the hardware transcoder off the video works (but the DS CPU is hurt).

Where can I find the old version to Download?

31

Good question, I don’t know where to download this from Plex. They only seem to offer the latest and I could not find a nice page with a bunch of older ones where you can actually choose whice version you want to download.
I keep these SPK’s myself too so I had no trouble re-installing *.1944

Plex crew should be able to provide you with a download-link or something.

Still the option to delete the ihd driver.

34

The iHD driver was corrected in PMS 1.18.3.2175

I do not know if it corrects everyone’s issues but it does correct the problem where the driver completely failed.

35

For those experiencing complete failure - not video quality problems, Please attach the ZIP (DEBUG) logs of a captured failure.

36

Well yeah, I’ve installed now 1.18.3.2175 and deleted the Intel-driver manually so prevent transcoding garbage. All works find with the existing i965-driver.

@ChuckPa, what do you mean “The iHD driver was corrected in PMS 1.18.3.2175” ?? Obviously the transcoding garbarge not entirely, at least not on my 918+ in combination with any transcoding client. (eg. Plex app on the Samsung S7 phone)
In cases where it completely trashes PMS you might, consider is fixed, I never experienced this.

37

What we were able to find and correct (with folks out on holiday) were those cases where the iHD driver would not work at all and completely block any transcoding.

If you’re familiar with linux ldd “rpath”, this is where we found the problem. iHD could not always find the libigdgmm.so. Since that library is required for iHD to load, the entire transcode session would fail.

The problem would vary from system to system which is what made it difficult to track.

38

@ChuckPa
Hi Chuck. Already tested the other versions around with my DS918+. Transcoding worked but the problem then was with the first 30-90 sec. Artifakts Pixelated.

The iHD Driver only affects my android clients — with subs, not so the ios or tvos clients with the enhanced player (only problem with the native one).

Now what to do?
Pms Version with iHD - No transcoding with subs.
Pms Version with old or fixed Driver - Artifakts, Pixalation the first 30-90 sec.

Any clue?

Gruß Markus,

Pixelation in the iHD is a problem. What makes matters worse is there is a known problem with ApolloLake hardware which the iHD makes painful obvious.

The Synology systems do not need the iHD_drv_video.so file at all. iHD_drv_video is only required for the -9xxx family CPUs .

Confirm please: Pixelation with or without iHD driver ?

@ChuckPa
Last Time i tested the Version of chrisallen, not the latest from him 4 days ago, the one before, (Weihnachtsstress😉) it transcoded well, but it pixalated 30-90 sec before picture was normal.

I must work tonight, but can try the latest tomorrow with logs if needed.

Why did all went well versions before and not now?

Already try to reach you with PM and Mail but no luck.

Wie gehts dir?

Meld dich mal.
