Error on start server "Can not load library"



We are updating our flashphoner instances in baremetal servers, to version 5.2.1536, running Debian GNU/Linux 10 (buster) .

When running in standalone mode, just to check the logs, we are seeing this message in all servers:

user@host:/$ sudo /usr/local/FlashphonerWebCallServer-5.2.1536/bin/webcallserver start standalone
FlashphonerWebCallServer-5.2.1536: starting
######### Start standalone mode #########
Can not load library cannot open shared object file: No such file or directory
Running command to install, seems it's already installed:
sudo apt install libx264-dev
Reading package lists... Done

libx264-dev is already the newest version (2:0.155.2917+git0a84d98-2).
0 upgraded, 0 newly installed, 0 to remove and 51 not upgraded
We test stream publish and play, and seems it's working fine, even with these error message in the logs.

This error is something we should concern about?

The library libx264 is not bundled with WCS package due x264 license limitations.
Therefore lib openH264 will be used instead of libx264 for H.264 encoding.
If you just install "sudo apt install libx264-dev", it won't resolve the issue.
So please ignore this log message as warning. Especially if it does not affect video encoding / transcoding.

For information. This log message says that libx264 not found and system will fallback to lib openH264.
