No videos after upgrading to PinballX ver 6.99

[Knievel]

Hi folks been awhile. I finally upgraded to a Win10 PC and decided to upgrade PinballX as well.

Seems to be working fine other than no videos showing - playfield, backglass or DMD.

I am coming from a really old PinballX version so maybe something has changed?

I installed the LAV filters from the download provided here. My videos are all F4V format.

Any ideas would be appreciated...

Please attach copies of your pinballx.ini and log.txt files when reporting an issue.

Have you tried converting some of your videos to .mp4 format?

Hi no I haven't. Could try it tomorrow if that might fix it. 

Would you know the easiest way to convert?

Thanks

@Knievel Can you post a screenshot of your 'LAV Video Configuration' screen and one of the flv videos as an example as well.

Tom's Convert-IT can probably convert files to mp4 (not sure), if not as a single file test you can probably just convert one online somewhere (you might get a watermark but it's just for a test and it can be deleted later)

Actually it might just be a bad nvidia driver update.

I just updated nvidia from v581.93 to v591.74 and i now have just black instead of videos playing. I imagine rolling back the nvidia driver will fix it, but i'm out of time to investigate further.

You can do single or batch file conversions - wizard driven and very straight forward. I would start with one or two files to test. Since the extension will be changed for the output (instead of EXAMPLE.F4V it will be EXAMPLE.MP4), you can convert from F4V to MP4 within the same location.

This wouldn't help, but I just wanted to mention it:

Since this summer, I have been using my powerful desktop PC for pinball as well. All was working, but a couple of weeks ago I noticed I no longer had video in the front end. I checked and reinstalled LAV, but no luck. I'm not sure if it's a 6.99 issue or something else. I'm not at my PC to post files, and I'm not sure if it is related to this issue, but I have never had this before.

I wonder if its newer video card drivers? i will do some testing.

[Knievel]

Ah yes! it was the Nvidia driver. I had installed the newest available for my card (591.74).

Uninstalled that and Windows installed it's default driver (576.52). All good now

Thanks everyone!

[Tom Speirs]

Well, just a temporary fix. ill look at it.

Hi, I'm having the same problem. With the latest NVIDIA driver, the videos aren't displaying. I uninstalled it, and it works with the driver that Windows installs.

[Mike_da_Spike]

I'm having the same issue. As a test, I removed the NVIDIA driver, and it works, but I need the NVIDIA driver as I use the PC for other things as well. So for now, I won't have videos in the frontend,  until this is solved.

Was this after an Express or Complete install of the latest driver?

[ingadri]

This happens in both installation options.

[Draco1962]

There's quite a bit of fallout with this driver and causing black screens in game play as well. Reverting to the previous may be the only option until Nvidia provides a fix.

I mostly do custom installs, unless I don't have much time. Then I will do an express install. I've already had it for weeks. I will try to test with older drivers

Anyone experiencing this error should report it to Nvidia - there is a dedicated thread:

GeForce GRD 591.74 Feedback Thread ( | NVIDIA GeForce Forums

Not sure if this is directly related for the issues encountered with PinballX, there is mention of issues with Steam that DLSS4.5 Model M causes the black screen for games there, while reverting to DLSS4 Model K appears to resolve it:

I’m still using GeForce driver 591.74 but have updated my LAV driver from version 0.77.2 (available on the PinballX website) to 0.81 (Download link). Now the videos are playing again

Could someone experiencing issues with the latest GeForce driver try to reproduce the problem, then install the 0.81 driver and see if it resolves it?

The link is from github https://github.com/Nevcairiel/LAVFilters/ but it shows the following :

I just click on the three dots on the right side (they appear when you hover over them) and click 'Keep'.

A second warning will appear, and you’ll need to click on 'Keep Anyway'.


I hope this works for other people as well.

Strange. Videos aren't working for me with LAV 0.81 and nvidia 591.74. Tried a reboot just in case.

This is just testing on a desktop with a RTX4060.

My LAV settings (which i think are default)

I do have Hardware accelerated GPU scheduling enabled in windows display/graphics/advanced graphics settings, maybe that's a factor?

[Mike_da_Spike]

I thought I'd found the silver bullet for my system, but I rebooted my machine and all screens were black again (so no video).

Not sure why it worked in the first place.

add me to the list of video problems after latest nvidia drivers.......

but unlike others rolling back nvidia driver is not helping.....I did get videos back after a complete video card driver uninstall,  but installed nvidia drivers from early December and videos are black again.

I also had a windows update at the same time, uninstalled that but no luck....... tried system restore....that won't work because I emptied the recycle bin apparenty......not fun times...

[keithhov]

got videos back using NVidia drivers from November...monitor positions and backglass positions all out of wack but not too hard to fix....I do have about 20 custom back glass postions because I have 4:3 backglass monitor................will check back here when it's safe to update drivers.......

First time I have ever seen Draco suggest going backwards on a driver!!! had to read it 3 times to believe it.

[Draco1962]

Nvidia driver v591.86 was released today (01/27/2026) - please update and see if this addresses the issues encountered. Thanks!
