Question

So for debugging purpose I'd like to pass some dynamic variables to the extractor (I have made some modifications to some of yours but also added new ones in my private repository).

I want to do something like this:
youtube-dl --pass2extractor tmpstore=html,json --pass2extractor pathprefix=$HOME/.tmp/%SOME_UNIQ_AND_DYNAMIC% -f .. -o .. "URL"

• tmpstore=html,json --> tells the extractor to save the webpages html (get variables for the json-link here), and the downloaded json (contains the wanted video-playlist-data)
• pathprefix tells the location for the html and json (I want store them in a different location than the video)

--pass2extractor %PASS% -> the content of %PASS% should get passed into extractor (it should somehow be available/accessable)

Is it possible to do this and is something like that already implemented?

There's already the --write-pages option for saving fetched web pages.

yt-dlp has implemented options similar to what you describe, so it may be useful to check those implementations:

• --extractor-args ... for passing extractor-specific parameters: this will soon have to be implemented here, to control client selection in the YT extractor;
• --paths TYPE:LOCATION to specify a directory to be used for the TYPE files.

I know this - but it doesnt work for me - i need custom path and filename >> more control over which html or json should be saved and where

Oh cool - will look at that later

Thanks for the reference.
