[SOLVED] Can I use my Android phone's camera as a webcam?

I'm in need of a webcam and rather than buying one I'm wondering if I can just use my phone's built-in camera. I have a Nexus 5X running Android 6.0.1. I've tried using the IP Webcam app along with this script, but the script didn't appear to work; I could view the stream fine in browser though.

Re: [SOLVED] Can I use my Android phone's camera as a webcam?

I haven't looked at the script, so I have no idea what it is supposed to do, but 'doesn't appear to work' is not helpful. How are you calling the script? What output (if any) is displayed? Does the script have a verbose mode?

Oh sorry, here's the output when I try to run it from a terminal:

$ ./prepare-videochat.sh

The script is supposed to make the device recognized as a regular webcam.

Re: [SOLVED] Can I use my Android phone's camera as a webcam?

Yes, you can. I used to do that before. For the purpose I used droidcam:

Linux client:
https://aur.archlinux.org/packages/droidcam/

Play Store client:
https://play.google.com/store/apps/deta … s.droidcam

It should work with wireless and usb, although I mostly used it with USB.
I haven't played with it from a long time, but it worked.

AUR package is out of date. Also it seems it can only do 720p; I'd like to do at least 1080p (my phone supports up to 4K).

Let me be more specific. Here's a very ugly PKGBUILD I just modified to work with the latest version:
