NOt work play video 6k or 8k. WHY?

[Delacroix]

how do i play video in 6k or 8k? when I open the file the screen vr is all black and when I start the video plays only the audio but not the video. Come to solve? what should i set up or install? I have a RTX 2070Super. help me pls!

ps. if i use skybox vdeo it also works in 8k if it is lagging..

None of the other VR players in steam works for me either, but in windows the 7k files and up plays a lot better. It's weird bc 6k actually works fine for me, but everything 7k and up it just refuses to play.

They had this same problem last year to this date according to forum posts I thought was today until I saw the year.
Started happening to me too a few days ago where 5k-8k vids are crashing the player (blue screen windows app store mixed reality vr app home scene), but it seems to be crashing something in the Steamvr, so it might be some update in that app or the player. I solved my vr windows mixed reality home scene problem by shutting overlay and home scene etc in edit and putting on headset after loading everything per others solution and that seemed to work make it more stable with the player except for the 5k-8k video situation....update: I had to turn off hardware acceleration in LAV to get it from crashing but of course that brings you back to the stutter issue.

let me know if you find a fix. I'm in the same boat as you stutter wise. I have the same vr headset and gpu 3070rtx and g2reverb

Do you have intel cpu or AMD? I'm wondering if the admission by AMD about the 550 motherboards with their chip set being the reason the USB turns off and disconnects the headset from time to time and is what happens in Cuvid graphics acceleration crashes on Lav filtersas possibly the culprit to not being able to use the GPU to decode the h265 vids which eliminates stutter.
I know the solution =changing cpu to gpu acceleration in the Lav Filters, but that solution crashes the VR Player and Steam VR and sometimes the USB connection has to be swapped out.
AMD is working on it, so we'll know upon updated drivers.
If you have Intel cpu then you can try my fix and let me know if it doesn't crash the VR.
Find your lav filter video config if you pinned it to start or from k-lite codec pack the codec tweek tool (find lav config in direct show filter config) and in LAV Filters change hardware configuration pop down to NVIDIA CUVID. NOw when testing the 5k-8k vids view a bunch for a while, becuase sometimes this fix works for a few vids or few minutes then the crash or spinning occurs frequently again including telling you your fresh batteries are low already.
Let me know the result, because this might help figure out if it's the conflicting chips that is causing this.

yea its 50/50. I do have a intel

update your nvidia drivers in Geforece experience, update your windows along with the new Steamvr update they might have fixed a few issues.
Then try using Intel Quick sync as your lav hardware accelerator setting instead of cuvid or none or dxva2, see if that helps some or most stutter using the cpu, if that doesn't work use dxva2 native as the graphic acceleration relay to the intel cpu and that should be much better (smoother but sound lag still exists) as long as you don't get crashes/blue screen/uncontrolled spinning.

I have no idea what happened but now I can play video in 7k or 8k videos without lags or other problems.. the quality is really impressive!

[76561199129841526]

You might have fixed your issue through an update (windows or drivers) or it might be that sometimes it works for a short time then crashes teasing you that it's working, but you might be playing h264 videos which are being done now when I had everyone all complain to the VR producers housed web sites about the HEVC h265 compressed vids they put out. The h264 being done on 5-6k vids now are working, it's only the HEVC turning on the directx that is not. 4k in Directx is fine though so that's what makes it hard to figure out.

HP Reverb G2 and RTX 3080 GPU usage is usually around 80%.
5k 60fps videos play okay, but can't even dream of using SVP4 Pro with this.

How are you getting the GPU acceleration, what is your lav setting? It crashes on my Nvidia Cuvid lav setting same headset and rtx3070 card. Do you have Intel cpu? If so, then Maybe it's my AMD CPU that is conflicting?

5900X, RTX 3080. Latest LAV Filters, DeoVR in directshow mode, CUVID decoder.
I don't think we are doing anything differently.

I've seen that too high resolution crashes apps though.. Can't go much above ~3000x3000.
Sometimes SteamVR defaults to about 3700x3700 on Auto when you check per-app resolution..

thanks

I downloaded the Lav filter 0.76. I tried CUVID whatever, but I don't see an improvement and it says "active decoder= inactive" "active hardware accelerator = none" It always says that, does that mean something is wrong? Seems like it isn't doing anything at all

just use heresphere, there is a free trial that works great

It might be related more to file size than video quality? I find high quality files cut into smaller chunks play ok, but if they are one large file it stutters like crazy, or gives chipmunk voice.

Same here with AMD 5600X & 68000XT. I'm using Quest 2.
