pipe screen to video device (udev)
Is there any way to pipe video from the screen to a video device that can be used as if it came from a webcam? I assume it uses udev somehow...

Hi welcome to LinuxQuestions! , Do you want to save the video of a webcam video, you can use screen video capture program like "xvidcap"
* you can capture a particular portion of the video * you can pause, resume while capturing the video |
Thank you for the answer, but that's not what I meant. I intend to redirect my desktop to a device file that can act like a webcam.
Alternatively, a way to edit the video that is output by /dev/video would satisfy my ultimate goal but take longer. |
I'm confused. A webcam is an input device; a display is an output device.
How you gonna get an output device to act like an input device? |
I think the OP wants to simulate the situation like: as if the stuff he sees on his desktop (screen) is actually coming from a (web)camera. I.e. the video card is the source (the camera) and this mysterious 'device' is something like an editing machine or whatever. Kinda like using `recordmydesktop` and piping the output to some external device?
:scratch: Maybe not though, and some further clarification (including the goal of this project) might help, if this is not the right idea. Sasha |
