Hi Giang,

I'm sorry I can't help with your question but have you tried linphone-daemon? I believe that this supersedes linphonec and linphonecsh.

I was pleased to see that were able to build linphone on Ubuntu. So far I have been unable to do so. The part I'm stuck on, is where the environment variable Qt5_DIR is set. I am unable to find the path for the cmake folders of Qt5.

Can you please tell me where your cmake folders are located - and if there's some specific package I need to install?

I am able to find the bin and I believe the path should be defined as:

PATH="/usr/lib/x86_64-linux-gnu/qt5/bin/:$PATH"

On my system "whereis qt5" yields:

qt5: /usr/lib/x86_64-linux-gnu/qt5 /usr/lib/qt5 /usr/share/qt5

I am using Linux Mint 19.3 which is based on Ubuntu 18.04.

Thanks. All the best,

Iain

Hi, I've created a virtual video device "/dev/video0"//using kernel module v4l2loopback and I'm piping RTSP video stream from an IP camera to that device: /ffmpeg -i rtsp://my_camera_RTSP_URL/Streaming -pix_fmt yuv420p -f v4l2 /dev/video0/
/
/
Now, I'm able to play it with VLC as from a capture device.
However when i use linphonec:
/$ linphonec -C/
/linphonec> webcam list
0: StaticImage: Static picture
/
/
/
linphonec seems not detect any video devices (I expected /dev/video0 should be there), just only the "/0: StaticImage: Static picture/" as per the output of command "webcam list". I also tried the GUI but no video device is detected there either.

I built linphonec from source, as described here:
https://gitlab.linphone.org/BC/public/linphone-desktop
with Ubuntu 19.10, 5.3.0-29-generic

I have know idea, what could be wrong.
Any help would be appreciated

Giang
