Any way to screen record

[muschellij2]

Is it possible to do a screen recording versus a webcam recording? I think it'd be an interesting addition, where stream(index = 1) for example, would allow people to record their screen.

I don't know the CV api well enough to see if this is possible/doable.

@muschellij2 A quick Google Search didn't return anything obvious. I'll keep this open as a reminder to investigate from time to time, but I don't know when this will happen.

@monkeychex3 As far as I know, there is no way to do this directly with OpenCV. So, as long as this is the case, I'll consider this feature outside the scope of Rvision. Besides, implementing this feature without using OpenCV would require relying on additional platform-specific libraries, which would add significant complexity to the project and my bandwidth is already stretched thin. If an R package exists that's already capable of doing screen captures (though I'm not aware of any), I could potentially write an interface with Rvision, but that's the extent of what I'll be able to do without external contributions.

I have made a simple wrapper for ffmpeg to try to do this with ffmpeg only. https://github.com/muschellij2/recordscreen
