webm audio only must have the opus extension #28041

webm audio only must have the opus extension. webm extension is for video.

Steps to reproduce: youtube-dl -f 251 'https://www.youtube.com/watch?v=iyB7zYiBPVo'

Expected result: .opus file

Current result: .webm file

WebM is a container for video (VP8/VP9/etc.), audio (Opus/Vorbis/etc.) or both. Also, changing the extension from .webm to .opus would still give you a webm file, just with a different extension.

if you want an opus file, add the -x flag like this:

 laura@iino  ~/haruhi-dl   master  youtube-dl -f 251 'https://www.youtube.com/watch?v=iyB7zYiBPVo' -x

I still believe the current behaviour is wrong.

1.

% grep webm /etc/mime.types                  
video/webm                                      webm

2. -f 140 produces m4a audio only file without -x

  1. I don't know what files do you keep on your PC, I personally don't have a one like that.
  2. That's the de facto standard, as you can read on Wikipedia: image
