A third party tool called FFpmpeg is used for generating animations from saved images in Linux. The tool is no longer installed with ADINA, but can be installed from various sources.
In the Linux verison of the AUI under the file menu is the option to save mpeg movie. This feature requires the third party tool FFmpeg to be installed. If it's missing, then a warning will occur indicating ffmpeg not found, and no movie will be created.
A warning also appear in the install log of ADINA when the FFmpeg component is missing.
The FFmpeg tool is available for various Linux distros as indicated on the FFmpeg website https://ffmpeg.org/download.html . Prerequisite files from various repos are required to install it on some Linux distros.
In order to create mp4 files, FFmpeg needs to be configured with the library "libx264". If FFmpeg does not contain this library, FFmpeg will fail to create mp4 files.
The Ubuntu ffmpeg contains libx264.
The Centos Stream ffmpeg (from the additional repos) contains libx264.
The OpenSUSE ffmpeg (from the OpenSUSE repo) does not contain libx264.
