Question about merging audio and soundless video files

jd1008
The audio file is recorded at bitrate 320k.
But after combining the audio and the video,
and running ffprobe, it shows that the audio
bitrate is 128k.
So, why would ffmpeg downgrade the audio bitrate?

Sounds like you re-encoded the audio using a default bitrate value instead of just re-muxing or re-encoding with your desired bitrate, but that is only a guess.

You should always include your actual commands and the complete console output from each command. You'll get answers instead of guesses. You'll get answers faster. People will be more inclined to reply.

OK.
Will do so as soon as I encounter the problem.
