[FFmpeg-user] FFMeg Concat giving "unsafe file name" error on new server install

[Steven Burns]

First time posting to this list, hoping someone may have a suggestion for an error I’m getting with a FFmpeg project.

Quick history - the application I have running is working fine on the original server Ubuntu 14.04.  I was cloning the process to a second server for a backup but one step in the process is failing for a reason I can’t seem to find documentation on:

The same process with same permissions and settings is working on the original box - Anyone experienced similar or have suggestions on what I could be missing?
