Description of your issue, suggested solution and other information

Attempting to load extracted wav files into a java AudioInputStream but receiving an error due to the Bit rate and length properties not being present in the file.

A file converted on convert2mp3.net added the following properties to the file and it worked flawlessly

However, using youtube-dl, it retrieves a file with the following properties

Is there an argument to add this kind of information to a downloaded video? I tried a view such as meta data.
If there isn't would it be possible to add?
Thanks, keep up the good work.

Edit: Done some more digging, --add-metadata tag mentions that is adds the metadata for videos, but I tried it for audio anyway with no success. Decided to check the output when running it, and apparently using the following settings
"youtube-dl.py https://www.youtube.com/watch?v=6Cp6mKbRTQY --add-metadata --extract-audio --audio-format wav --output /Songs/6Cp6mKbRTQY.wav", the following error pops up at the very end.

Could you paste the whole output of this command:

youtube-dl.py -v https://www.youtube.com/watch?v=6Cp6mKbRTQY --add-metadata --extract-audio --audio-format wav --output /Songs/6Cp6mKbRTQY.wav

Please paste as texts. Don't paste screenshots.

@Tomhoogstra Could you try this:

youtube-dl.py -v https://www.youtube.com/watch?v=6Cp6mKbRTQY --add-metadata --extract-audio --audio-format wav --output /Songs/6Cp6mKbRTQY.%(ext)s

[Tomhoogstra]

It creates a file with unknown extension

[yan12125]

The percentage sign in %(ext)s disappears from your command. If things are still broken after fixing the command, please test this: --output 6Cp6mKbRTQY.%%(ext)s.

[Tomhoogstra]

@yan12125 Yes, using this command
youtube-dl.py https://www.youtube.com/watch?v=EbJtYqBYCV8 --audio-format wav --extract-audio --add-metadata --output /Songs/EbJtYqBYCV8.%%(ext)s

It adds the meta deta correctly, and even converts it to wav like I wanted it to.
So in the end it was a user error I guess.

[yan12125]

Yeah. Windows is tricky.

Closing as problem solved.

This doesn't work for me.

youtube-dl -x --audio-format "mp3" --audio-quality 0 -o "/Music/%(uploader)s/%(title)s.%(ext)s" --metadata-from-title "%(artist)s - %(title)s" --add-metadata https://www.youtube.com/watch?v=0sjR0-EG3BM

The artist and other metadata is not set.
On Windows.

@Spenhouet That's a known bug. See #5594

[Spenhouet]

@yan12125 I did find out what's the problem: If the first downloaded file format is .webm then, this file doesn't contain any metadata. Therefor the converted .mp3 file also doesn't contain any metadata.

I added this command: --format "bestaudio[ext=m4a]"
Now it's downloading a .m4a file and saving the metadata correct (also in the converted .mp3 file).
