4K HDR to 1080p SDR w/ PGS burn-in

Nvidia-smi is an instantaneous snapshot of the activity.

I only need nvidia-smi to confirm the drivers & kernel are in sync and the card is seen.

May I see the DEBUG log files which capture a transcoded playback ?

So it’s your display driver too?

scarbrtj · September 11, 2022, 9:46pm

If you’re asking if my Plex server is hooked up to a display, yes

ChuckPa · September 11, 2022, 9:48pm

I run my machine completely headless and in “ubuntu server” so I don’t have all the screwy BS which is Gnome. (It is quite a load on the machine)

Please grab the logs when you can and attach here so I can look through them

scarbrtj · September 11, 2022, 9:54pm

I actually drive three screens with my RTX 5000. One 1920x1080, the other two 1280x720.

Thank you for the logs:

Yes, it’s being seen and used for the video transcoding element

I see all the data getting pushed to be transcoded.
The client goes only a few blocks then gives up.

Notice the “PUT” (video sent to transcoder)
Notice the “GET” (where the player pulls the data)
A new session is started (there are now 3 sessions active)

The more I look through this,

This does not look like a server problem
Expressing that 480p / 1.5 Mbps works. <— symptom.
Let’s confirm definitively, the network status

Now.

IGNORE the transcoder speed. It will often be 0.0 (sloth mode)

Humor me please:

Install iperf3 and run in server mode iperf3 -s on the Linux macine
on each client:

iperf3 -c IP.addr.of.Server -t 20
iperf3 -c IP.addr.of.Server -t 20 -R

now we can confirm there are no networking or other latency problems between player and server.

I expected the LAN to be fine. Anything 8+ is good given the other traffic on the server.

Now how about the remotes which have this problem when trying to transcode?

scarbrtj · September 12, 2022, 3:34am

If by remote do you mean a client that is not on my local LAN? It doesn’t matter if the client is on, or not on, my LAN (and I have 1Gb upload/download internet connexn). PGS doesn’t burn in w/o a hiccup in the video (ie buffering) every ~15-30s when it’s a 4K HDR to SDR transcode.

Have we answered the question… is anyone burning PGS with 4K HDR to SDR (I guess, besides me, when I turn the quality down to 1.5 Mbps).

I have built a server with a i9-9900K, one with a 10980XE… I have tried Windows, I have tried Linux… I have tried 32GB RAM, 64 GB… I have tried quadros, I have tried a 3090ti… I have tried DAS and NAS … I can not get PGS subs to burn with 4K being tonemapped down.

I was checking the other thread. Seems video buffers too for your server when 4K HDR to 1080p SDR 20Mbps with PGS burn (with the Roku client)? This has been the Plex behavior … forever afaik…

ChuckPa · September 12, 2022, 5:14am

That’s a problem with the roku client. I’ve spoken to the Roku dev and given him a sample file to work with.

I am going to PM you that same sample file.

It’s the same file I now show here.

Same behavior with my Chrome client: about 15-20s of smooth playback, about 5s of buffer… repeat. Transcode never gets above 1.0… and same behavior in Edge.

ChuckPa · September 12, 2022, 6:26am

Turn off the HDR tone mapping.

What happens.

Where I’m going with this is probably going to upset you.

Tonemapping is either done in the Intel GPU (normal opencl graphics) or software.
You don’t have Intel OpenCL. (Does AMD have standard OpenCL drivers for you?)
Turning off HDR tone mapping should confirm you’re getting software SDR and burying the CPU

You can verify the behavior (with on and off) using normal ‘top’, not ‘htop’, and interval set to 5 seconds.

If it’s not the HDR-SDR then it’s the Nvidia GPU drivers.

Process of elimination given a controlled source.

Info:
On Intel CPUs below CometLake (where Intel changed how their internal normal GPU was accessed) the Beignet package uses OpenCL (opencl-icd-libopencl1) to talk to the hardware.

Starting with their -10xxx CPUs, the access to the regular GPU and OpenCL side of it changed. They created a whole new toolkit to do it: Intel Compute Runtime.

Based on this, the challenge is to figure out the recipe, if one exists, for AMD; which Plex does not support in spite of what the internal GPU can do.

scarbrtj · September 12, 2022, 12:32pm

When I turn HDR tone mapping off, you may not believe me, but the HDR STILL TONEMAPS TO SDR. Why would that be? The behavior of video stuttering/buffering every 15-20s is gone. Tone mapping seems prior; video not desaturated (looks great in fact). Transcode speed surpasses 1.0 indicating video is not prone to buffering. (Below I am playing back at 20 Mbps in Chrome at home in LAN and another user is accessing offsite by cell.)

@ChuckPa … this is very confusing. Is turning off tonemapping the answer? Again video does still tonemap even if I turn it off.

Before I try further troubleshooting, we already know Roku “stumbles” (even with your server which on paper is a lot weaker than the one I am running). Are you saying your server doesn’t buffer or “stumble” when using Chrome or Edge as a client when doing 4K HDR played back at 20 Mbps with PGS burn in and tonemap turned on? I have asked this question here…

Have we answered the question… is anyone burning PGS with 4K HDR to SDR

… multiple times. Would love an answer lol. I have plenty of high power intel pc’s lying around that I can load PMS on…

ChuckPa · September 12, 2022, 3:04pm

Answer:

If you have an Intel CPU — YES, it works

I am likely saying this not 100% correctly but

When you turn off HDR tone mapping (as explained to me)

Writes a flag in the first block of the manifest to signifiy H.264 10bit instead of 8 bit standard
Then transcodes HEVC BT 2020 → H.264 10-bit
Lets the device, especially the browsers, tone map on their own (which many can do now)

On Intel,

When enabled with Beignet/OpenCL, the real HDR tone mapping is done in hardware when enabled
When not enabled, tone mapping is handled by the player as it displays H.264 10-b it

scarbrtj · September 12, 2022, 9:37pm

It looks like, at least, I don’t have server buffering anymore by turning off HDR tonemapping. I keep HW encode and decode turned on.

Just to restate: the video tonemaps properly. But by turning off tonemapping, I can now achieve HDR->SDR with PGS burnin using a Ryzen processor, Quadro card, and Ubuntu.

@ChuckPa … you guys really need to check HDR sources with PGS playback on multiple clients. Today I discovered w/ PGS burnin on Xbox S, it forces a 4K->1080p resolution downgrade w/ PGSs. Even with directplay and directstream turned on. HDR source plays directly when PGSs don’t get invoked.

scarbrtj · December 4, 2022, 9:21pm

EPILOGUE

Now that 64bit windows and PMS does tonemapping, I loaded the latest PMS on a i9-9900KF Z390 PC with a Quadro RTX4000. I tried to play Train to Busan 4K with subs on another PC on the same network transcoding to 20Mbps (burn subs, obv). There was stuttering and the PC could not keep up; about 20s of smooth play, 15-20s of pause, rinse, repeat…
