adding extra characters to the original file name

[adeebothman]

after using youtube-dl -t {link} to download playlist from youtube
it download file very well, but it adds extra characters to the file name like this one
ex: this command
[ youtube-dl -t https://www.youtube.com/playlist?list=PLAwxTw4SYaPnMwH5-FNkErnnq_aSy706S ]
should download the first video with this title "Welcome to Developing Android Apps"
instead it downloaded with this one " Welcome to Developing Android Apps-2Wo_QfQZ0lE.mp4"

finally thank you for such a great tool it changed my life 👍
i hope we can figure the solution soon

It's intentional. Use -o "%(title)s.%(ext)s".

The -o option specifies a template for the filename. It is not recommended to actually replace anything in there.

You're passing in the option -t, which is equivalent to -o "%(title)s-%(id)s.%(ext)s" (which is, coincidentally, also the default behavior). This makes the filename include the video ID, which is extremely useful if you want to find the original video URL in a pinch.

If you only want the title and extension (there are lots of other fields too), pass in -o "%(title)s.%(ext)s" instead of -t.

If that's the behavior you want all the time, consider creating a configuration file.
