    You need the -x option in order for youtube-dl to save the OPUS from the downloaded file. It seems that whatever option you choose in terms of format, you always get a container file that holds video and audio (mp4, webm, etc).

    -x gives you the .opus

    I get exactly the same file whether I use -x or not:

    ERROR: ffprobe/avprobe and ffmpeg/avconv not found. Please install one.

    The only diff is that -x is a post-operation after the download.

    Did you notice the ERROR: line in your output for the second command? The error is that ffmpeg/avprobe cannot be found. Youtube-dl uses ffmpeg to extract the OPUS stream from the .webm into a .opus file. That is the post-processing. Because you don't have ffmpeg or avconf, the post processing fails and you are left with the .webm container, instead of the .opus.

    do you ever use it do download a playlist? does it barf on you when there's a missing entry?

    i have it do that and then stop everything.

    I have used it to download playlists, and by default it will just stop. Use the '-i' option to ignore errors, then it should continue on its merry way with the next video, if it happens not to be able to download one.

    Hello Boraxman!

    Youtube-dl uses ffmpeg to extract the OPUS stream from the
    .webm into a .opus file. That is the post-processing.

    fails and you are left with the .webm container, instead of
    the .opus.

    Yep. I am aware that -x is a post-operation. I was just
    demonstrating that there is no difference in file sizes whether
    one uses -x or not.

    In that case I can play .webm files directly from a USB plugged
    into my mini media player that is connected to the TV. I don't
    need to post-process to just get an audio file.

    Sometimes I use an older version of FreeMake to convert to .mp3
    if I need that.

    i'll try it again once i found that playlist. i usually do the continue switch and the ignore errors for programs like curl and wget
