Everything wrong with DroidCam and how to solve it
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)
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
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
And you never mention what problems this solves.. I use the package manager version of v4l2loopback and have no problems, and it auto updates. And I would use a package manager version of droidcam for the same reason.
ah... problems like v4l2loopback not found. I used to face it a lot, and I never found the reason why it was not working in the same place (I might get one thing here and another thing there) so I tried to aggregate everything and create this post, so that people who face that issue would get this post and they won't stay confused for a long amount of time like I did.
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 [email protected]: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.
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.
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
That one seems to only do remote streaming over network. Droidcam can be used over a USB connection as well, which works much more reliably (than the wireless version of droidcam, at least) in my experience.
