With all the video calls, twitch streaming and product demo work I've been doing recently, I've been building up a library of tricks for using my android devices within the video content I produce from my laptop, so I thought I'd share. I've worked remotely for many years but I think there's more of us not going back to the office any time soon, so strong video communication skills are important!
(I also have the Behringer UMC404 audio interface, meaning I can route the phone headset audio directly in to my computer but honestly my earlier solution of plugging from 3.5mm headphone socket on the phone into a basic bluetooth speaker and turning that right up worked almost as nicely! It only matters because I work for a communications company and sometimes need to demo phone calls)
Android Phone as a Webcam.
I've been using DroidCam who seem to be much better at making android apps than they are at making marketing websites! It connects over USB (using adb again) or over wifi. I found that some days only one or the other will connect but once it's stayed connected for 30 seconds then it has usually been rock solid for me - although it does seem to like to be reinstalled if Ubuntu has had updates!
I have been using it as a second camera, in addition to my built in laptop webcam, so that I can include my hardware projects in my Twitch streams. If I work on software, then I only need screensharing but for something that is not on a screen, the second webcam is really handy. At some point I might get an actual webcam, but I started doing this at the start of the pandemic and getting a webcam was pretty difficult - and the phone works fine for the hobby level stuff I'm doing.

Again, this one is my basic work phone, so it doesn't get much in the way of notifications or anything which I think helps.
Adding Android Devices into the Video Mix
It takes time to figure out the tools and set them up in advance of whatever you need them for, but I've found it to be worth it. I use the phone with a gorillapod and basic phone tripod mount and I've found it useful for sharing many different things (including a storybook at bedtime for the little ones that I can't put to bed myself right now!). Let me know what you're doing with your extra devices in your video setup? I would love to hear!
