SLR choppy unusable streaming performance

harigeharry how and where?

diwanga Well the best way is to make an exclusive 5G wifi SSID in your house (don't share the same SSID with 2.4G) and connect to that. Look up your modem/router manual on how to do that. If you're connected to 2.4G you're most likely connected at 72mbps, which will result in about 50-55 mbps effective max which WILL cause stuttering on higher mbps files like the SLR originals. That's what's happened to me. I then noticed that when I connected to 5G, it actually connects at 200 mbps and things were suddenly working well.

Of course your problem might be a different one but first thing to do is to make sure you're connected to an exclusive 5G SSID.

JangoSLR > Direct Ethernet Connection: If you're using Wi-Fi, try switching to a direct Ethernet connection.

Is this some kind of canned AI bot response? Tell me how I’m supposed to connect to an Ethernet cable on my headset? I’d love you to breakdown this “support” and explain how this is remotely useful. We’ll wait.

Do you people actually test the issues people report?

diwanga Tell me how I’m supposed to connect to an Ethernet cable on my headset?

Probably referring exclusively to PCVR (headset connected directly to PC, then PC on ethernet).

JangoSLR

diwanga We’re currently in the process of completely restructuring our support to make it better and more efficient for you. I’m still new to the team, and while I’m doing my best, I may make mistakes from time to time.
Please accept my apologies, and I promise I’ll keep improving to provide you with better service in the future. 🤗

diwanga tell them how

Yup, making people hunt around for it isn't helpful.
He's maybe referring to Deo VR Settings >> Privacy >> Clear browser cache on exit

Tried clearing the cache, no effect.
Lowering the video resolution is unacceptable as a solution, I pay a yearly membership to stream at the highest quality available and I have the hardwire and internet connection to support it.
Router is not throttling
Already on 1gbps ethernet.

issue occurs across all videos, doesn't seem to be tied to any specific video.

JangoSLR

Thank you very much for providing the information. I’ve informed the team, and we hope to resolve the issue as soon as possible. If I have any updates or ETA, I’ll get back to you.

CraveDastry What is your set-up by the way? Since you say that you are connected to ethernet, it seems you are not using DeoVR on a headset like Quest 2/3.

netcat

@CraveDastry Probably already verified, but can you check the video is playing using H265 encoding and not 264?
It might be hard to troubleshoot. Your headset (bigscreen beyond) is not super common, and most folks here won't be familiar with it. It might help to get an idea of your overall hardware setup.
It sounds like you're using a PC connection to play the content. Can you provide details on your PC specs?

GPU specs.
Does your machine have multiple GPU's (especially dedicated card + integrated gpu)?
While running a video, what does the GPU utilization look like in performance monitor?
While running a video, CPU utilization of DeoVR and the orchestrator process (ex SteamVR or what you are using instead).
Type of cable you are using for connecting to your PC. If USB, check the usb port version that you are plugging into. Also note if you are using any hubs/adapters.

4090
single gpu, HMD is plugged into that, deovr worked has worked for months flawlessly with current setup
GPU/CPU utilization is normal in system monitor
in SteamVR (bigscreen beyond is a native SteamVr device) I do get frame spikes once the stuttering issue begins in Deovr and the frame rate monitor in DeoVr oscillates wildly
HMD is displayport and 2x USB 3.0s both USB's are plugged in mobo 3.0 ports. Notably I can play high end PCVR without issue so I don't think I'm experiencing a system wide performance issue, it seems to be limited to deovr specifically and once the streaming video begins freezing the issue persists

CraveDastry

netcat oh and I've tried H265 and 264 and the issue seems to persist with either one but generally Im on 265

harigeharry

Maybe try saving the video (max quality) to your PC and play it from there in DeoVR (using a windows share). If that still stutters, try playing the video in 2d on the PC. This could be useful in helping you to find out what the problem is, because this obviously is a problem on your end in your setup somewhere.

CraveDastry

harigeharry locally saved files play just fine in DeoVr so it appears to be a streaming issue

netcat

Yeah, it does sound like a DeoVr specific issue, and not system wide. And unfortunately I don't have a lot of expertise in SteamVr.

But I do have one suggestion - this may be a faulty codec issue. Can you try re-installing your codecs using the instructions below? Then re-install deovr as well for good measure?
You may have done this already in the past, but it's possible that an update in the meantime messed something up so that they are not working with DeoVR correctly. Even if other apps are fine.

LAV Filters installed
https://github.com/Nevcairiel/LAVFilters/releases
Install HVEC 265 Codec from Microsoft store
Install Codec Tweak tool
https://codecguide.com/download_other.htm

--Settings--

Codec Tweak tool, click 'Preferred Decoders' under Win7DSFilterTweaker. For h.264 and HEVC, make sure LAV is selected for both columns.
In LAV Video Configuration, enable hardware acceleration, D3D11.

Also, one other small thing. After the above, also set the process priority in task manager to 'High' for both steamVR and DeoVR.

Very curious to hear if this makes a difference at all.

While we're at it, let's also rule out network stability/packet loss. Can you run this test for 30 minutes, and share the results:

CraveDastry

netcat performed the test, didnt have a video call but I streamed a high bitrate video the whole time

Total packets Sent: 11392, Received: 11392

Call Quality Estimation:
Overall estimated call quality score based on round trip delay, jitter and packet loss rate.
4.5: Excellent (Imperceptible)
4.0: Good (Perceptible but not annoying)
3.0: Fair (Slightly annoying)
2.0: Poor (Annoying)
1.0: Bad (Very Annoying)

Your Results: Average Score: 4.39, Minimum Score: 4.39,

Packet Loss Rate(%):
Packet loss happens when a packet does not arrive, arrives out of order, or arrives too late.

10.0: Might cause frozen video and broken audio.
= 2.0: Might cause low video fps, and audio quality might be affected.
< 2.0: Video/Audio quality will not be affected.

Your Results: Average Loss(%): 0.00, Highest Loss(%): 0.00,

Average Round Trip Time(ms):
Time it took to send a packet to server then receive it back.

300: Might cause unnatural delays in an audio conversation and disconnect between audio and video.

Your Results: Average Delay(ms): 20.1, Max Delay(ms): 23.0,

Average Jitter(ms):
Inconsistent arrival of packets between two endpoints.

50: Might cause certain packets of information to drop or sent out of order, leading to a jumbled conversation.

Your Results: Average Jitter(ms): 1.64, Max Jitter(ms): 7.00,

Sorry, one more. Last one I promise (sorry to spam thread)!

In DeoVR settings, can you disable DirectShow?

CraveDastry

netcat already tried disabling directshow to no effect
