hello @bashonly , thanks for your fast reply and for your fix, but I'm not very familiar with Python, neither with the yt-dlp workflow. Is there anything I can do to apply your patch or it will be released soon in some specific version of yp-dlp?
Thanks. Regards

I'm also very interested in this fix, but I don't understand where I need to insert this code snippet to make it work.

@elpresti yt-dlp --update-to master
