metadataFromTitle not working?

[mostafa-norouzi]

Hi,

Anyone tested metadataFromTitle switch?
I'm using below pattern :

->metadataFromTitle('%(artist)s - %(title)s')

but output mp3 has no metadata!
https://github.com/ytdl-org/youtube-dl/blob/master/README.md#post-processing-options

Also :

->postProcessorArgs("-metadata title={$title} ")
is working but I want to fill title automatically from video.

Hey. Which yt library you are using, yt-dl or yt-dlp?
Looking at the yt-dlp parse-metadata should be used which is not implemented here, but PR's are welcome.
Could you check if that option works for you in terminal?

[mostafa-norouzi]

I mentioned the URL, It's youtube-dl. Also I checked the code and metadataFromTitle implemented in PHP. you are right, I should check it in terminal first.

youtube-dl has no releases since 2021, so I'd suggest to switch to yt-dlp

[mostafa-norouzi]

I used below command:

youtube-dl -x -R 3 -r 500K --audio-quality 128K --metadata-from-title "%(artist)s - %(title)s" --user-agent "Mozilla/5.0 (Android 14; Mobile; rv:128.0) Gecko/128.0 Firefox/128.0" --audio-format mp3 -o "%(id)s - %(title)s.%(ext)s" https://www.youtube.com/watch?v=b8I-7Wk_Vbc

And metadata is empty! So it's not related to the wrapper

Where do you check if it's empty? I haven't used this option never

[mostafa-norouzi]

Simply in Winamp (windows). It shows complete metadata (with hotkey alt+3) like title, artist, cover and .... This option of youtube-dl can save user time (no need adding data manually). These days most of software check and shows meta-info like Telegram, Media player, cars audio player and ...

Also there is a tiny app that shows and modifies it :

Maybe that option is not for the ID3v1/ID3v2 ? Will check this someday,but no promises

[mostafa-norouzi]

Finally I found the reason! The right pattern has two % sign and should be like this :

->metadataFromTitle('%%(artist)s - %%(title)s')

Cool! Maybe you could add a section in readme file about this for others :)
