OS: Linux Mint 19.3 with Kernel 5.3

I am using the latest code.

$ sudo ./install-videochat.sh 
videochat installed, launch with './run-videochat.sh'
$./run-videochat.sh

Phone is connected to computer via USB, and I have USB debugging enabled, adb installed in the computer, and IP Webcam server is turned on in phone. This dialog appeared.

IP Webcam audio is streaming through pulseaudio sink 'ipwebcam'.
IP Webcam video is streaming through v4l2loopback device /dev/video2.
You can now open your videochat app.

After clicking ok, the terminal output is,

Press enter to end stream

I opened Cheese, only my internal webcam shows up.

After pressing enter I get

./run-videochat.sh: line 455:  7003 Terminated              "$GSTLAUNCH" -e -vt --gst-plugin-spew --gst-debug="$GST_DEBUG" $PIPELINE > feed.log 2>&1
Disconnected from IP Webcam. Have a nice day!

Am I missing something simple?

You probably need to enable exclusive_caps=1 for Cheese (and Chrome) to work correctly with it.

$ # manually unload the v4l2loopback module
$ # (only needed if already loaded without the necessary parameter)
$ sudo modprobe -r v4l2loopback

$ # use V4L2_OPTS to pass extra parameters when loading v4l2loopback
$ V4L2_OPTS=exclusive_caps=1 ./run-videochat.sh

For more information, see umlaeute/v4l2loopback/#78.

I still get the same error

V4L2_OPTS=exclusive_caps=1 ./run-videochat.sh 
Loading module
modprobe: ERROR: could not insert 'v4l2loopback': Bad address
mail4me9999 commented 4 years ago

this error is due to incompatibility between the v4l2loopback and the kernel. need to recompile the module from source. this is not a problem related to this script

I am closing this as the solution in #100 worked for me. Please add the solution proposed in #100 to the README. Also, I added this line (https://github.com/apandada1/ipwebcam-gst/blob/master/run-videochat.sh#L278) for my own use. I don't know if that may break functionality outside Ubuntu 20.04. Can something similar be added to the code and can it be selectively loaded with exclusive_caps=1 in Ubuntu?
