  • SLR choppy unusable streaming performance

@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?

  1. GPU specs.
  2. Does your machine have multiple GPU's (especially dedicated card + integrated gpu)?
  3. While running a video, what does the GPU utilization look like in performance monitor?
  4. While running a video, CPU utilization of DeoVR and the orchestrator process (ex SteamVR or what you are using instead).
  5. 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.

    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.

      2. single gpu, HMD is plugged into that, deovr worked has worked for months flawlessly with current setup
      3. GPU/CPU utilization is normal in system monitor
      4. 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
      5. 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

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

            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.

            1. LAV Filters installed
              https://github.com/Nevcairiel/LAVFilters/releases

            2. Install HVEC 265 Codec from Microsoft store

            3. Install Codec Tweak tool
              https://codecguide.com/download_other.htm

            --Settings--

            1. Codec Tweak tool, click 'Preferred Decoders' under Win7DSFilterTweaker. For h.264 and HEVC, make sure LAV is selected for both columns.
            2. 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.

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

            In DeoVR settings, can you disable DirectShow?

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

              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)

              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.

              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.

                Any effect from re-installing codecs using instructions above?

                  CraveDastry hello; personally (and I'm not the only one, maybe headsets other than quest): since December deo lag; so for me personally the only solution: use an old version of deo; and it doesn't lag.

                      CraveDastry Dang, I'm not sure what else to try. And this stuttering happens at all resolutions, or just at the highest?

                          it plays just fine at max resolution for 10 minutes or so before the problem starts

                          CraveDastry Hmm, and once the stuttering starts happening, does skipping the video forward or backing out and restarting the video temporarily fix this?
