Just curious, does your system lock up, if you select RGB colorspace in either VCS or OBS? As it does for me.

In my case (windows) if I used the datapath directly in OBS as "webcam" it died with RGB. However there is a plugin called RGB easy, and that works.
VCS worked fine for me. So when I used VCS I basically recorded the screen of VCS in OBS.
Been trying this in Linux. If only one program accesses the card, it works fine. But if another device tries to do so, I have to hard-reboot. Mostly trying to use VCS with OBS.
By the way, did you ever get the newesr VCS to compile in Windows?

I have absolutely no experience with that. I think for me, like for lots of people this is black magic. ^^
The current version of VCS doesn't include any explicit support for Windows. It's a modular program so you can implement support for Windows capture devices, but that's a bunch of work besides just compiling it.
Gotcha. Also, will probably open an issue for it, but in Linux I can't use it at the same time as OBS. Always forces me to hard-reboot. So I have to use one or the other.
You could try various combinations, like two instances of VCS, OBS + mplayer, OBS + Datapath's app, Datapath's app + VCS, etc., to see where the problem might be. Is there a need to capture in two programs at the same time though?
I know in the past when it came to sub-VGA raw capture, using VCS with OBS helped a lot for systems that had multiple resolutions and refresh rates (MegaDrive, PS1, Amiga). Having VCS open with a reolution set I made, would ensure the capture was free of shimmeting pixels without having to manually-adjust mid-stream.
Unrelated, it seems VCS (and Datapath's own Vision program) really don't like Wayland.
Hi,
recently I’ve tried to find some information about but not much available, so please let me share my experience.
My goal:
I want some cheap solution to be able to record some footage from my old graphic card with VGA output. I want to use also under DOS, to basic VGA modes and text mode are important.
Solution:
I’ve found some very cheap VGA to HDMI adapters on AliExpress. There are very cheap, so I’ve tried:
1) Full HD 1080P VGA to HDMI-compatible Converter Adapter Cable With Audio Output VGA HD Adapter for PC laptop to HDTV Projector
https://www.aliexpress.com/item/1005002524532 … .7e021802qOr5rv
The description was not very good, but I like the design – short cable, no need for cable or no heavy load to graphic card connector, easy to swap.
Unfortunately, this one does not support text mode at all. It has also some problems with VGA modes but I haven’t investigated very deeply, text mode is essential for my intended use-case.
2) VGA Male to HDMI-compatible Female Converter with Audio Cables 480P/720P/1080P for PS3/4 HDTV Monitor Projector PC Laptop TV-Box
https://www.aliexpress.com/item/1005002173117 … .7e021802qOr5rv
This one was much more promising, there is better description and there are mentioned supported modes, including:
... 720x400@70Hz, ...
So, text mode should be fine. I’ve tried and really, text mode works. I’ve run Checkit 3.0 text and graphic test. Everything has been shown, so I would say – basic VGA is supported well. Tested on Radeon Rage 128 pro AGP. I’ve tried on HDMI display and HDMI-USB grabber.
But there is one common issue – screen is shown but slightly shifted to the right. And there is no way to manually correct.
So now I’m able to get some forage, only problem is unpredictable screen shifting which can vary based on graphic card and graphic mode with no way to manually correct…
Please share your experience, what do you use?
I bought also cheep HDMI USB grabber.
So there is record of Ckeckit tests:

Why not just capture VCS in OBS?
Wayland may be a Qt problem. I don't use it so don't know.
Will give a try. Turns out that the cause of all my issues with the E2S, was a DMA protection setting in the BIOS. Now that I disabled it, both cards are working great (though the VisionAV doesn't seem to like sub-31KHz RGB sources, I'll need to putz more with).
PSA. VCS is no longer a public project. There are forks available for those interested.
Hi Guys. I would like to small express my experience about VGA/SVGA grabbing. After so many things I bought and tried ... And as I was starting to be rly lost I tried a solution thatbcosted me 25EUR...
And the overall quality is just superb! What is more it is grabbing even 320x200! There is no latency, no loss quality of sound or video ....
Here is some little testing. In this video we have 640x480 quality grabbing and FullHD@60fps is available but due to fact that I was grabbing on very small HDD the resolution was low and fps to 30fps ....
See it for yourself, perfect solution!

https://youtu.be/bTD6QkmGTwg?si=gLPs2mpraufb9Nxm
Again resolution set for grabbing to 640x480, medium quality.
OBS, NCH works flawless!
Well... I miss 80/90s ... End of story

Well, it kinda depends on the quality you expect. That said, the youtube video might also not be super representative as I think for that resolution it will also use worse compression.
What is also a problem is the scaling. I am not sure what exactly your device does and what is due to the recording, but you basically stretch the pixels while keeping an incorrect aspect ratio.
I mean it's nice that it can actually handle 70Hz at all. But the quality so far isn't too impressive.
Ah, didnt see the edits yet: The other videos besides Doom are significantly better as they are not stretched out.

Ok so it depends on OBS or other software but on general it accepts 16:10, 16:9, 5:3, 4:3 and manual aspect ratio, deinterlace as well. As mentioned 640x480 is set and medium quality but still it looks great, and yes YT made quality worse as I can see.
Tommorow I will set quality as best option + maxed out resolution, for discord purpouse I had to lower it (25MB limit).
But hey.... Show me other option for ~25EUR that handles everything from DOS era without problem.
Well... I miss 80/90s ... End of story
I got a RetroTINK-4K and an Elgato 4K X for streaming DOS games with. I'm sure there's cheaper solutions out there but this one is relatively easy to set up and "just works" for DOS games running at typical resolutions.
I've been streaming a playthrough of Eye of the Beholder for my friends and I've been having a blast so far. It really motivates me to get through games where I may get bored with them otherwise.

Yeah, I am using the Retrotink4k as well, and it's pretty good!
However, the Elgato 4k X is not to be recommended. It's an external USB card, and that one can't do RGB capture. That the card can't do RGB will be extremely obvious if you check in Norton Commander and DOS Navigator, and have some Red Font on Blue background, which will look quite messy.
4k RGB cannot be achieved with USB as far as I know due to bandwith limitations. EposVos recommended 3 Cards for the purpose of capturing 4k RGB:
Avermedia Live gamer 4k GC573 (cheapest at around 140-165€)
Elgato 4k Pro
Elgato 4k60 Pro MK2
These are all internal cards.
Personally I tried some USB capture cards from Elgato first, realized the RGB issue, and then switched back to my Datapath Card. Not to change analogue to digital but just to record the RGB signal in 1080p until I buy a 4k capture card. I will wait with that until I change my whole setup to 4k.
