Capture Card which runs ONLY under Windows 7

Skilowi · 2026-01-09 14:56:25

Howdy!
I am an owner of CaptureCard - StarTech PEXHDCAP - which runs ONLY under Windows 7.
I tried under Linux: it doesn't detect what it is. It only called it as some Philips chip. OBS couldn't use it.
Windows 10: if you tried to use the capture card even with official software (which is written in Flash) system hangs and only resetting the entire computer helps.
I have built entire 2014~ Windows 7 computer just for this Card. To record on it I lobotomized Windows 7 to most basic thing, autoran OBS on it and connected to it using VNC. Videos were shared to my computer over Samba.

Previously I was searching if theres any X server for Windows 7 so I could just ssh -X to that computer and run OBS from there but no luck (if theres even such possibilty).

VNC wasn't perfect. Couldn't make framerate higher than ~10fps. (Both computer are connected over Ethernet on 1Gbit switch)

Before building that computer I wanted to run Windows 7 on my previous computer, but it's B450M mobo with Ryzen 5 3600 and Windows 7 refuses to work on it. What I want to do is try to run on this B450M computer Linux with Windows 7 VM by QEMU.

Could I somehow passtrough that card to the VM?
Maybe there is some X *server* (not client) for Windows 7?
Or maybe there are some drivers for this card for Linux?

I managed to plug the card from win7 computer to the 5 3600 computer.

This askubuntu post seems to indicate that support has been removed for that card in later kernels but was there for version 5.?? of the kernel. I would suggest getting an old ubuntu .iso file put it on a USB stick then boot to see if it works for you with an older kernel in one of those versions.

saa7134 covers a chip w/ the PID 12ab but f501 is no vendor ID
@Skilowi, that's not the output of "lspci -k", , is the implication that it lists no kernel module (in use or not) for the chip?

Here's the full one.

But no kernel module is affiliated or loaded.
The ID isn't aliased for saa7164 but you could try to just "modprobe saa7164" and see whether it's picked up regardless (not overly likely, though https://www.linux-club.de/forum/t/gel%C … ost-759603 suggests support was added there in 2014)

There used to be https://github.com/ljalves/linux_media/ … ci/saa716x but all comments and commits on the driver are ancient and it doesn't look it's been upstreamed.
It at least doesn't exist in eg randomly https://github.com/torvalds/linux/tree/ … /media/pci or https://github.com/torvalds/linux/tree/ … /media/pci

So far I tried Ubuntu 18.10, 20.04 and 20.10 and none supports this card right away.

I found this:
https://www.linuxtv.org/wiki/index.php/NXP_SAA716x
https://github.com/ljalves/linux_media/ … ci/saa716x

But this driver is supposed to support NXP, Twinhan and Azureware cards. No mention of Startech[.]com. (they all use same SAA7160 chip?)

https://www.startech.com/en-us/audio-vi … s/pexhdcap

Here they say that PEXHDCAP has *partial* support on Linux. Whatever that means.

Have you checked whether saa7164 picks up the chip? (As mentioned, not likely but worth a shot)
If not you'd have to compile the OOT driver, but will likely run into several issues w/ modern kernels - so it's gonna be easier to just get a $10 DVB-T USB dongle with a chip that's covered by an in-tree module or forward the device to a Win7 VM

cryptearth · 2026-01-10 21:34:39

although likely not helpful
i made the same mistake in the early 2010s by building a system around the then new elgato 60hd
although it worked with win7 (and later win10) as os for the stream system i never got it to work with linux
from elgato themself the only ever statement was: this card is based around DirectX DirectShow and hence no efforts where ever made to even try to get it working on linux

point is: many grabbers back from those days just were designed around windows specific features without any intentions to make them work with linux
long story short: unless you need external input (to capture a console) most systems these days should be powerful enough to record/stream with minimal performance impact
if you need external inout: spare yourself the time and effort and just spent the few bugs for a grabber known to work with linux - i recommend something external based on usb3

So far I tried:

Ubuntu 10, 18, 20, 21, 22
Debian 8
Arch Linux

Each recognized Philips SAA7160 with no issue but had no drivers for it. We talking about various kernels from version 3 up to 5.

@seth, modprobe saa7164 brought sadly nothing. I will try to build saa716x

Not quite the solution. The DVB and TV signals arent my focus. This card can capture DVI, VGA and HDMI. I have few computers and laptops from which I would like to record screen from, but they can't do it on their own in uncompressed native resolution since they have Intel Pentium at whopping 133MHz and 80MB of EDO RAM or C2D with just 4GB of DDR2 667MHz RAM.

While trying the PCI Passtrough to VM I had few problems. I will have to try again since it is quite complicated. Now I will change the OS to Ubuntu 18 and try to build the saa716x there.

This is the command I cooked to run all of this:

qemu-system-i386 -cdrom Windows7.iso -drive file=hdd.img,format=raw -m 4G --enable-kvm -cpu host -device vfio-pci,host=06:00.0 -drive if=pflash,format=raw,readonly=on,file=/usr/share/edk2/x64/OVMF_CODE.4m.fd -drive if=pflash,format=raw,file=/home/skilowi/OVMF_VARS.4m.fd

When ran it returned

qemu-system-i386: -device vfio-pci,host=06:00.0: vfio 0000:06:00.0: Could not open '/dev/vfio/13': Permission denied

When I ran it with sudo:

qemu-system-i386: -device vfio-pci,host=06:00.0: vfio 0000:06:00.0: group 13 is not viable
Please ensure all devices within the iommu_group are bound to their vfio bus driver.

What I didn't understand from manual: do I have to passtrough ALL devices from IOMMU group 13?

EDIT: When qemu command was only long up to -cpu host part it ran with no issues - managed to install Windows 7.

Yes, but that's impractical - can you move the card into a different pci slot?

I can try but then all working has to be done by ssh. Mobo has only 2 PCIe slots: 16x and 1x. 1x has Capture Card while 16x is occupied by GT710 because mobo nor CPU have no iGPU.

Skilowi · 2026-01-11 15:10:48

Partial success:
Capture Card was detected by Windows 7, driver and startech software worked. Now what did NOT work is OBS, because of lack of proper GPU.

For now I went back to the old setup GT 710 in 16x and Capture Card in 1x. First I want to make GT710 work in Windows 7, then isolate Capture Card from rest of IOMMU group and pass it to the guest. For now GT710 is visible in device manager, driver installed but I am having error 43.

I am running with only qemu, no libvirt.
-cpu host,kvm=off does not help.

I am using SeaBIOS, because EDK2 does not boot - it just stucks on Guest has not initialized the display (yet).
And chipset is i440FX, Q35 causes the bluescreens during boot.

seth · 2026-01-11 15:16:46

Forwarding your only GPU(?) to the windows VM means that you cannot use it on the linux host.
What would preclude you from (dual-)booting Window 7?

Skilowi · 2026-01-11 16:02:25

I know, thats why I connect to the machine trough ssh -X

And can't run Windows 7 on this computer. When I install it it just says it cant run on this hardware and shuts up. It's because of the motherbard: Asrock B450M HDV R4.0

Skilowi · 2026-01-11 20:43:46

Okay so. First computer can't load the nvidia drivers in VM no matter what I do and second computer cant do IOMMU (Intel H81).

Second computer will get turned into Windows 7 Gaming PC (8GB of DDR3, i5-4590T and GTX760 from my shelf instead of that capture card) and in first one I will have to change case and mobo for ATX. Question is what mobo should I take?

Is there some resource or database of motherboards in which I can find good mobo for virtualization?
Or is there someone with knowledge what mobo would be least problematic? Requirements are: AM4, DDR4, ATX, supports IOMMU and would be nice if cards in each slot were separate IOMMU groups - would be a nice convenience :-)

Iommu groups and virtualisation compatibilty depend on motherboard design, cpu used, chipset used and possibly some other factors.

Server / workstation systems tend to be the best, but the am4 only supports ryzen , no epyc or threadripper systems.
Best to start a new thread for that.
