Linux

The GNU/Linux module (prototype) is a combination of a Video4Linux2 device driver, and an executable app that will transfer the stream from the phone to the driver.

It’s assumed you are somewhat familiar with the system and how to use the Terminal. Also please keep in mind other posts on the blog are Windows oriented.

Install

1. You must first remove any old versions of the client you have. Scroll down to the “Removal” section below.

2. If you are using an older Android device, check the version of DroidCam that was installed from the play store and run the appropriate commands from below.

For DroidCam & DroidCamX version 6 and above (newest):
cd /tmp/
sudo apt-get install linux-headers-`uname -r`
bits=`getconf LONG_BIT`
wget https://www.dev47apps.com/files/600/droidcam-${bits}bit.tar.bz2
[[ ${bits} -eq 32 ]] && checksum=59a125f2b312bcb2a6421a1f69beefd1
[[ ${bits} -eq 64 ]] && checksum=dddc9f6321620662a60036a1383e5780
echo "${checksum}  droidcam-${bits}bit.tar.bz2" | md5sum -c --
# OK?
tar xjf droidcam-${bits}bit.tar.bz2
cd droidcam-${bits}bit/
sudo ./install

For DroidCam & DroidCamX below 6: [show]

Please download one the following packages to /tmp, extract and run sudo ./install 640 480
64-bit (f937c3510615af68c007b8c72deadb14), or 32-bit (73c6b9d853a0a6ab7c6d15174450a3f1).

* If you are running the newest Linux kernel (version 4 or above) and seeing errors, make sure your installed gcc version is 4.9 or above:
uname -r # prints linux version
gcc -v # prints gcc version


3. Once everything goes without error, you can ensure the device is installed with lsmod. Look for ‘v4l2loopback_dc’.

Open up a V4L2 compatible program (VLC player, Skype, Cheese, etc) and you should see DroidCam listed as a video device.

4. Start droidcam via the Terminal, or create a launcher if you’re using gnome. You can also try droidcam-cli -h.

5. Check the connection post on how to connect. If all goes well, you should see the output in the chat application, and you’re done!

A note about USB connections: The latest version of the client will try to invoke ‘adb’ automatically, provided the executable is found via the $PATH environment variable (ie. export PATH=$PATH:/path/to/adb).
The following commands are automatically executed:
adb start-server
adb devices # Look in output for a connected device
adb forward tcp:$port tcp:$port # $port = specified port on the client

The Linux client is open source.

Update webcam resolution

You may change the webcam output resolution as follows:

1. Close any programs using the droidcam webcam. Unload the device driver:
sudo rmmod v4l2loopback_dc

2. Re-load it as follows (WIDTH and HEIGHT are numbers). :
sudo insmod /lib/modules/`uname -r`/kernel/drivers/media/video/v4l2loopback-dc.ko width=WIDTH height=HEIGHT
Recommended resolutions: 320×240, 480×360, 640×480, 960×720 or 1280×720.

3. Restart the droidcam client to reload the settings, and test it out. You can keep changing the resolution.

4. Edit the text file /etc/modprobe.d/droidcam.conf with the new options to make the change stick.

Removal

To remove the DroidCam client (or existing old version):
Close any running programs. Run one of the following (depends which version of the linux client you got)
sudo /opt/droidcam-uninstall
# OR
sudo ~/.droidcam/uninstall

    Hello,
    bought the app because it has Linux support, but i downloaded the 64-bit client from this site and the app says ‘pc client outdated’. Will there be an update soon?

    I have error when trying to install your program. I am using Ubuntu 16.04. Dont you have any PPA ?

      Hello,
      No there is no PPA, and please use the more generic install guide on top of this page – that works with most distros without having to deal with all the different package management systems they use.
