DroidCam is a freemium application which allows you to use your phone as a web camera (thus getting a better picture quality for meetings than ordinary webcams)
So, needless to say, it’s very helpful.
Now, I have been facing a number of issues with this application for a few days and I felt it would be best if I just share stuff regarding how I make it work seamlessly, it won’t look good when you are late for a meeting because you are troubleshooting droidcam, so here’s how I use it.
- v4l2loopback package can cause a lot of problems, so, I would suggest you to download it from source, you can do that using this script given below (this also installs droidcam on your linux computer)
This isn’t the most efficient script there is, but it works.
First, run the command
vim installation_droidcam.sh && chmod +x installation_droidcam.sh
(you might have vi editor installed by default, so if you don’t have vim, just replace vim
with vi
, if neither are available, run sudo apt install vim
, I personally use featherpad)
Now, paste the below script into your text editor (this doubles as a reinstallation script too, but if you want the latest and greatest, you would have to replace the installation commands of droidcam given below with whatever is available here on the official website
#!/bin/bash
cd ~
pkill droidcam
sudo /opt/droidcam-uninstall
# installation script for droidcam
# if you want the latest version, go to
# https://www.dev47apps.com/droidcam/linux/
cd /tmp/
wget -O droidcam_latest.zip https://files.dev47apps.net/linux/droidcam_2.1.3.zip
# sha1sum: 2646edd5ad2cfb046c9c695fa6d564d33be0f38b
unzip droidcam_latest.zip -d droidcam
cd droidcam && sudo ./install-client
# end of installation script
cd ~
sudo rm -r v4l2loopback
pkill droidcam
gh repo clone umlaeute/v4l2loopback
cd v4l2loopback
make && sudo make install $ sudo depmod -a
cd ~
sudo modprobe v4l2loopback
Now, save the script and exit it.
Everything required for droidcam to work has been installed on your laptop (you would still have to install Droidcam (green) on your android device and set it up over there tho, I am not gonna guide with that)
Here’s a video for that by Mental Outlaw
Now, you would have to edit the desktop entry for droicam on your laptop to include sudo modprobe v4l2loopback
command, because this needs to be running for droidcam to work. So, to do that, we will create another script
run vim /home/$USER/droidcam_start_menu_libre_desktop_file.sh && chmod +x /home/$USER/droidcam_start_menu_libre_desktop_file.sh
and paste the below script and save it
#!/bin/bash
sudo modprobe v4l2loopback
/usr/local/bin/droidcam
After this, menulibre if you don’t have it already by doing
sudo apt install menulibre
and edit the desktop file entry for droicam such that it looks like the image below (make sure you Tick Run in Terminal) as you need to have v4l2loopback
running in the background for droidcam to work.
In the command text box, you much have /home/$USER/droidcam_start_menu_libre_desktop_file.sh
(location of the script we just created) and now save it.
And that’s it!
From now on, you would be able to start droidcam (while keeping droicam on on your android device) The terminal would open, enter your password and you can now connect and use your phone as a second camera (a much better second camera)
I haven’t been very articulate, so doubts are welcome
Creating a script with privilege escalation is a terrible idea. How do I know if this does not install binaries in the root in some unknown directory?
You don’t need to do all of this - there’s probably a simpler and better way to do this. Maybe create a service, or something similar?
I am hard of hearing, can you please say that slowly :')
Sorry, please explain a lil more
You’re running a script that you downloaded off the internet, which isn’t deterministic, with a sudo
command, as opposed to using a relatively deterministic binary on a substitute server from the distro maintainers themselves. The better solution is to just use the Flatpak version of OBS, which comes with a DroidCam plugin, or Nix, or maybe Guix, if that’s what you prefer.
Your script uses gh, which I think is the github cli, to clone a repository.
It would be easier for most people to just do a git clone git@github.com:umlaeute/v4l2loopback
(or git clone https://github.com/umlaeute/v4l2loopback
). I don’t really understand why you’d use gh for something as simple as a clone tbh.
everything about cams kinda sucks, hope the pipewire camera project can address most of it
hey, what ya mean? Droidcam is actually perfect for me, I use it for Zoom, video calls, meets, you name it!
The only issue was reliability and I apparently just had to have v4l2loopback running in the background, and I solved that by creating a script and running that script to open Droidcam
I just use scrcpy. They have instructions on their github.
wot!? Scrcpy can double as a webcam, God, kill me now.
I have been using scrcpy to open the phone so I can turn on droidcam on it! :')
XD yea. scrcpy --video-source=camera --no-audio --v4l2-sink=/dev/video0 --no-playback
this is the command I use. There are a few more config options for orientation and to select the camera.
