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 for your version.

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-${bits}bit.tar.bz2
tar xjf droidcam-${bits}bit.tar.bz2
cd droidcam-${bits}bit/
sudo ./install


For DroidCam & DroidCamX below 6:
Please download one the following packages to /tmp, extract and run sudo ./install 640 480
Downloads:
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! Remember to delete the install folder from step 3.

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

    Upgrade to latest version of flash.
    Base version of ubuntu 15 desktop
    Base version of firefox

    html5 recognizes device but no picture
    flash does not recognize device.

  2. Robert says:

    … more got flash to the same place as HTML5 by adding the web site to the “allowed sited” in the global settings of flash. Now both flash and html5 can see the camera but there is not video.

  3. Robert says:

    … taking the browser out of the equation cheese gives me nothing either. hmmm

  4. Robert says:

    Client is running and connected.

  5. Robert says:

    $ sudo droidcam
    [sudo] password for robert:
    Device: Droidcam (v4l2loopback)
    Found driver: /dev/video0 (fd:5)
    connecting to 192.168.0.97:4747

    Isn’t sound available in Linux version like it is in Windows?
    Anyway, thank you for your work
