I have managed to reduce the output from the CLI when converting downloaded radio programmes to MP3, with the addition of the command “-loglevel repeat” to the commandradio entry in the Option file ie

commandradio ffmpeg -loglevel repeat -i "<filename>" -c:v copy -c:a libmp3lame -b:a 320k -id3v2_version 3 -write_id3v1 1 -y "<dir>/<fileprefix>.mp3" && del "<filename>"

However it does not seem to have any effect in the Web PVR.
Is it possible to achieve this in the Web PVR
