Description of your issue, suggested solution and other information

I use the same command-line arguments, with the video 9DxeMowxDTU I can change the --audio-quality to what every I want 0-9 or bitrates, it always stays the same (-acodec copy), other formats like ,mp3, ,acc "take" the quality accordingly.

Why does this happen with this video and/or only with opus?

Further research:

I get that "-acodec copy" would be ok if the source-webm-file would be the same bitrate as the parameter for the audio-quality, but it isn't (and I want to change the quality no matter what).

If I download -f mp4 the --audio-quality parameter IS passed on. Files with *.webm same to get the copy parameter no matter would audio-quality you choose for the opus file:

Conversion will only happen when original format does not match --audio-format. DLzxrzFCyOs bestaudio vorbis => conversion. 9DxeMowxDTU bestaudio opus => no conversion.

but the bitrate should still change, shouldn't it? it's opus but not the bitrate which is passed on, it should get encoded to a lower bitrate
