i used that command but how i can download a selected track like japaness or hindi pls give instructions

[dirkf]

The instructions assume that you've read the Manual, especially the concerning the -F and -f options, and also Format Selection.

If the language of the tracks is not clear from the format listing, you would have to guess. As always, post a full verbose text log of any command that doesn't seem to be doing what you expect from the documentation.

@mahaveergautamji the audio tracks are labelled in the -F output with their 2-letter language code. For example:

python3 -m youtube_dl -F https://www.youtube.com/w

However, it doesn't seem there is a way to get the video with a specific language track as audio - all the video options will be "video only", so you will have to download the audio you want and then post-process to combine it with the video (I think ffmpeg can combine audio and video).

[dirkf]

Formats labelled video-only have no audio language by definition. They may possibly have burned-in subtitles that imply a specific language: it depends on the site and extractor as to whether that is reported in the extracted metadata, as the language attribute.

To get a desired audio language, you specify the language code, say pl for Polish, as the value of language for the audio format, so -f 'bestvideo+bestaudio[language=pl]' (Windows: '...' -> "..."), or, if there are language-specific combined audio+video formats, `-f '(bestvideo+bestaudio/best)[language=?pl]'.

Example showing that the language of the selected audio format matches the requested selection:

$ python -m youtube_dl -f 'bestaudio[language=pl]' -o '%(language)s' --get-filename HwAPLk_sQ3w
pl
$
