Easiest way to capture Domain 0 windows?

Hi folks,

What’s the easiest way to capture a window in Domain-0 and push that into a guest?

Do I need to build a basic streaming application to do the capture to then push that into the guest?

I can get v4l2 installed and working, but I can’t attach the device to a guest because “dom0 doesn’t expose video10”…

How can I FORCE the attachment?

I have the same question. Would be good to get some YouTube guides out on how to use this wonderful OS in a reasonably secure way.

At this time I have to use my splitter and capture device to do it, but to do another screen I have to change cables out for the splitter, but I can’t do it for my DVI display…

So it can be done with hardware, I just want to be able to do it directly without having to use other things.

I mean I can use my networking version, but that adds even more overhead than having to use a capture to /dev/videoXX, and that uses more than my splitter and capture device. But the splitter and device is just unreliable. And I don’t have enough PCIE ports to get other cards installed to do it.

I have Qubes as a server still, with full remote access to Domain-0, SECURELY.

I already have FFMPEG to do things… That’s the EASY EASY EASY part…

I’m not asking about RECORDING… Please read the post before you actually reply so you actually reply to the issue, not just being completely random…

So you’re saying it’s a specific window you want to capture, as opposed to the whole screen? And you want to pipe that to a specific qube, instead of handling it in dom0. True?

I actually have have set up 4 videoXX devices, and I have 4 FFMPEG piping to these videoXX devices…

Now I want to attach these videoXX devices as video capture devices to the guest…

This is what the OP wants… So why not answer the question instead of saying other random things?

I just posted about this, lol, hopefully that answers your question?

@Vael_S If an answer is off-topic, you can ignore it, no need to repeat that this answer is random.

If i ignore it, then the person will not learn from their mistakes.

I would expect people to do the same thing for me.
