Hi
Do youtube-dl option --extract-audio extracts audio without reencodinng?
I mean is there option -c:a copy in ffmpeg postprocessing after downloading original video?
I want to be sure that the audio is preserved in its original (native) codec.
Thanks!

Depends on whether custom --audio-format is specified or not.

For example
youtube-dl -f 251 -x https://www.youtube.com/watch?v=ZRSNy8DcIDk
What happens here? Does transcoding occur in this case, or just saving original stream without transcoding?
