Subject: FFmpeg is very verbose and shows a bunch of errors. Those errors
 (they can be considered as warnings by us) can be ignored as they do not give
 any useful information. There is no solution to fix this except for turning
 error-messages off. They can be enabled if EnableFFmpegErrorOutput (in
 UAudioDecoder_FFMpeg) is defined (undefined by default).
