Install Minimserver 2.2 on NUC Linux

[Smjazz]

MinimServer 2.2 runs great, now trying to install ffmpeg on NUC Linux. I downloaded ffmpeg 4.2.2 amd64 static tar xz, extracted folder, found ffmpeg executable file, on Linux desktop in downloads copied the file, went to MinimStream on desktop, opened it, found opt folder, opened it, found bin folder, opened it and copied ffmpeg executable file in folder. In miniwatch, filled in System stream.converter field with opt/bin/ffmpeg and in stream.transcode field added aiff:wav, flac:wav, and hit Apply and OK. But when I run the Lumin app the app shows the files as aiff or flac, and the same on the front of the Lumin D2 music player. I tried the same procedure with release 6.0. Even restarted MinimStreamer and NUC. No conversion seems to be taking place. Where did I go wrong?
