MKV audio bitrate metadata issue

[Learning2do]

Hello what makes mkvtoolnix different from ffmeg.

I asked help for my ts to mkv remuxing and i got help. ( https://forum.videohelp.com/showthread.php?t=392621 )

Now i have another issue that is when remuxing with mkvtoolnix mkv gets audio bitrate visible for mediainfo usage.

When remuxing with ffmpeg it doesnt show xxx kb/s info at all. Is there anything that could fix this issue.

Audio format is AAC if that helps.

By default mkvtoolnix writes statistic tags for every track including average bitrate. MediaInfo can read and use them. You can map the metadata from source to target in ffmpeg but beware that the tags are copied and their values become invalid e.g. if you re-encode a track.

Hello what makes mkvtoolnix different from ffmeg.

aside from both being able to multiplex to mkv there isn't that much they have in common,...

What does your ffmpeg call look like that you use for remuxing?
Did you use the audio bitstream filter? (depending on your usage it might be needed,... https://ffmpeg.org/ffmpeg-bitstream-filters.html#aac_005fadtstoasc)

Nevermind, sneaker was faster,..

for %%a in ("*.ts") do ffmpeg -i "%%a" -c:v copy -c:a copy -metadata:s:a:0 language=eng "%%~na.mkv"
pause

Im feeling totally lost. I have managed edit @pandy version that i got earlier to have author and description metainformation.

for %%a in ("*.ts") do ffmpeg -i "%%a" -map 0 -c copy -metadata:s:a:0 language=fin -metadata Author="AuthorName" -metadata description="FileDescrtion" "%%~na.mkv"
pause

Its almost what i want as it has all needed metainformation other than that lost audibitrate. I didnt see anything that could add audio bitrate metadata information. Can someone please guide me.
