Segmentation fault (core dumped)

Description

This error may occur when trying to add a stream

Solution

To fix the problem, you need to install the nscd package

in ubuntu/debian:

sudo apt install nscd

in fedora/centos:

dnf install nscd

Reason

For Linux, we use a static ffmpeg build from https://www.johnvansickle.com/ffmpeg. In readme.txt there is a note to the assembly:

Notes:  A limitation of statically linking glibc is the loss of DNS resolution. Installing
        nscd through your package manager will fix this.
