FFmpeg libavcodec error

Just trying to add the ffmpeg codecs to my Fusion 17 (under Centos 7.6) and when invoking Fusion, an error message is shown which says
Ignoring unsupported FFmpeg AVCodec Ver 57.107.100
None of the FFmpeg codecs load.
Using FFmpeg version 3.4.12.
Reason for wanting to do this is to firstly get back the ability to generate H264 Quicktimes, which vanished, and secondly a new project requires the delivery of Photojpeg Quicktimes.
