In our Innards section, how we use droidcam!

And finally, the feedback and a few suggestions

LINUX INNARDS

Droidcam

  • Joe
    • Tested out Droidcam.  The setup on the phone is simple and the instructions on https://www.dev47apps.com/droidcam/linux/ make it really simple to make it visible to the system. The video quality was good but not as good as it could have been but the latency over wifi was non existent. It looked like it was real time.
    • Also set up ip webcam because it is something that I have used in the distant past that is similar.  The video quality was much better than droidcam which applies some paywall limits to its quality and the latency was also very good.  But the setup to use it as a computer webcam is a bit more difficult than that of Droidcam. Just follow the directions online to set up an ip cam as a computer webcam.  
    • But seeing the two side by side you can really see the difference in video quality using the Note 10 Plus
  • Leo
    • Been using Droidcam for 6 months now as a USB webcam
    • I’ve used it mostly for Zoom, but I’ve given it a run with Cheese and VLC for testing over USB. The quality is actually quite good, but defaulted to 640×480. To crank it up to 720p, you need to reload the module
cd /tmp/

wget https://files.dev47apps.net/linux/droidcam_latest.zip

echo "73db3a4c0f52a285b6ac1f8c43d5b4c7 droidcam_latest.zip" | md5sum -c --

unzip droidcam_latest.zip -d droidcam && cd droidcam

sudo ./install

sudo insmod /lib/modules/`uname -r`/kernel/drivers/media/video/v4l2loopback-dc.ko width=1024 height=720
    • This is special for me. For some reason, 1280×720 stretches me out. 1024×720 gives me a higher resolution, without stretching.
    • Overall it’s great in VLC, Cheese and Zoom.
    • Such a good option if webcams are not affordable.
  • Tony W
    • Found this app since Covid-19, while investigating live streaming
    • My son has been using DroidCam every day for school.  Remote learning with Zoom meetings
    • Android version wired capability does require USB debugging enabled, which in turn requires turning on Developer options (not difficult but not n00b friendly either)
      • Developer mode needs to be allowed in Google Family Link, so one more hurdle for devices with parental controls
    • Wireless was actually really good but wired is rock solid
    • Why do you need this?
      • Have a computer without a webcam?
      • Even if you do have a webcam, is your phone’s camera better? (will require paid version of app to get full HD resolution)
      • OK, maybe you already have one video source – but do you want more?  How about multiple video angles for OBS Studio?

One thing that Lynis has brought to my attention is that of security

issues with the following services:

Running ‘systemd-analyze security’

         – ModemManager.service:                               [ MEDIUM ]

         – NetworkManager.service:                             [ EXPOSED ]

         – accounts-daemon.service:                            [ UNSAFE ]

         – acpid.service:                                      [ UNSAFE ]

[truncated for length]

Consider hardening system services [BOOT-5264]

     – Details  : Run ‘/usr/bin/systemd-analyze security SERVICE’ for

each service
