> ... I would like to notify that the opus ogg tag editing is not working. Music is encoded with latest FFmpeg (ffmpeg-20151203-git-085ab74-win32-static) ... mp3tag Version: 2.72a. Error: "File ABC.XYZ cannot be opened for writing"

Just a quick shot into the dark ...  
it seems that this FFMPEG version applies "encoder=Lavc57.16.101 libtheora" too (for the embedded cover picture), instead of alone "Xiphophorus libVorbis", when having parameter on the cmdline: -codec:a libvorbis.  
Although displayed on the screen log output, existing tag-data will be not transferred.  
It seems like a problem in the FFMPEG recoding process or in the cmdline options???

But ... recoding a given ogg file ...  
ffmpeg.exe -i "beanbonus.ogg" -codec:a libvorbis "bb2.ogg"  
... creates a new ogg file with a tag-field:  
ENCODER: Lavc57.16.101 libvorbis  
... this seems to be ok, ...  
and Mp3tag can work with this file.

EDIT  
This sequence of two ffmpeg.exe commands does work ...  
ffmpeg.exe -i "Soundfile.mp3" "Soundfile.wav"  
ffmpeg.exe -i "Soundfile.wav" -codec:a libvorbis "Soundfile.ogg"  
... and Mp3tag does accept "Soundfile.ogg".

EDIT  
These piped ffmpeg.exe commands does work ...  
ffmpeg.exe -i "Soundfile.mp3" -f wav -|ffmpeg.exe -i - -c:a libvorbis "Soundfile.ogg"  
... and Mp3tag does accept "Soundfile.ogg".

EDIT  
These piped ffmpeg.exe commands does work ...  
ffmpeg.exe -i "Soundfile.mp3" -f wav -|ffmpeg.exe -i - -c:a opus "Soundfile.opus"  
... or ...  
ffmpeg.exe -i "Soundfile.mp3" -f wav -|ffmpeg.exe -i - -c:a libopus "Soundfile.opus"  
... and Mp3tag does accept "Soundfile.opus".

EDIT  
This standard ffmpeg.exe command does work ...  
ffmpeg.exe -i "Soundfile.mp3" -c:a libopus "Soundfile.opus"  
... and Mp3tag does accept "Soundfile.opus".
