[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..

if it's a black screen then you need the latest LAV filters downloaded, it's supposed to tell you that message when it draws blank. What headset are you using to get Skybox to work?
I'm not getting vids to play outside the thumbnail in Skybox on PC Mixed reality.

ahh okay, will it fix further lag problems? I use hp reverb g1

I use reverb2 the lag is still there on 6-8k video, more so on this recent update then before the update I'm afraid. I have a rtx 3070 that gets skipped frames and mismatched audio.
We probably have a setting on in nvidia or something that is causing the stutter if it's not the high bit rate producers release. Hopefully someone will figure out what's causing it, soon.
IN the mean time check out my response to the stutter in other topics, the setting in Nvidia 3d control panel settings to Higher performance on DEOVR player might help some instances.

yes, I already checked that thread and did as you suggested :)

After testing my fixed settings:
This worked for me in many videos it improved, and in corrupt videos where some frames are not fully downloaded and fluid it improved performance in that even more so, making it more playable then before.
This might help some, I found mine was off
enable hardware acceleration:
Hardware acceleration is where certain processes - usually 3D graphics processing - is performed on specialist hardware on the graphics card (the GPU) rather than in software on the main CPU. In general you should always enable hardware acceleration as it will result in better performance of your application.
Find Hardware Accelerated GPU Scheduling in Settings
Open Start Menu and tap on Settings cog icon.
In Settings, click on 'System' and open 'Display' tab.
Under the “Multiple Displays” section, select “Graphics settings”.
Turn on “Hardware-accelerated GPU scheduling” option.
Restart the system.

but also check before restart:
First turn off in settings -Gaming-the game recordings
turn on game mode in settings-gaming-game mode
turn off in settings-gaming-captures-background recording and also turn off audio recording

Just noticed some processes running that made my controllers spin everything and cause problems, it possible these also interfere with fluid stable video play.
The process in task manager were Iobit driver updater and iobit advanced system care that intrusively load sometimes, even if you have it disabled in start up. Also some windows apps load intrusively I noticed Office was loaded in processes without my knowledge, make sure processes has no weird things loaded that might interfere or use resources unwittingly.

Okay thanks a lot, i will try everything you said and let you know. it will necessarily be something software because I had tried an 8k video with the "Virtual Home Theater" program and magically all the video fluid, without lag or blocks.

OK finally got rid of 90% of the stutter on 5-8k vids, only VR being buggy does sometimes a stutter occur, which is not the settings fault.
If you didn't pin Lav filters configuration properties to your start menu you will need to reinstall the latest filter .74.1 and choose to save to start menu then because of some glitch in the start menu it won't show up as an icon in your windows apps start menu you must choose it at the start menu "recently added" (top ofg the list), select the 3properties config files related to lav filters and select to pin them all to start so you can always change configs as needed. When installing it allows you to set the properties but without it being in your access menu only installing will allow you to change configs.
So that in mind
in LAV Video configuration you want video settings tab, go to hardware acceleration pull down and if you have Nvidia GPU you select Nvidia Cuvid, now it will use your GPU instead of maxing out your cpu. If you have another type of graphics card then choose DXVA2 copyback which will allow your blacked out hardware to be selectable to your graphics card, once again allowing gpu to accelerate your decoding of the coded video not the CPU.
Let me know if that solves your problems it did mine, an 8k video was flawless sound and all when I test it out.

I did as you suggested. there is an improvement but it is still not smooth animation

Exact same problem starting at 7k video. up to 6k actually works fine. Used statistic on MPC-Player in just win10 and it shows that Sync-Offset goes above 1k ms, then it stutters hard to sync again and whole process repeats every 7 secs or so.

Tried to turn off A/V sync to see if the video will at least play smooth in MPC. No luck so far but its WAY smoother than DeoVR while sound being heavy out of sync too but not catching up with a stutter. Something is def off syncing sound and video together.

RX 5700 XT goes around 70-80% load and resets with every stutter.

Also using LAV codecs.

Right now I'm having serious issues with mixed reality vr home scene auto turning on and erroring out the player so that is interfering but if you remove it nothing works without the app. Anyone know how to turn it off from loading up the home scene, I use the windows app desktop to load ther player in steam vr and don't need the other home scene lounge especially when it's obviously interfering.

[KingQuokka]

Valve Index, 6K VR movies just give me a black screen in deovr and I don't see any prompt to update or use an alternate codex, anyone have any suggestions?

[Z1 阿遠]

can not play video 6k or 8k too

[Delacroix]

it's a problem with the program itself. i gueaa they will need to apply a patch to support video 7k and up (?) did you do as it was suggested before?

[76561199129841526]

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.
