Thank you very much! just for future reference after you comment i realized that the problem lies on some strange behavior of windows cmd file parameters expansion, I've a little script that did something like this:

getfile.cmd: youtube-dl --extract-audio --audio-format mp3 "%1"

and i use this command like:

getfile.cmd https://www.youtube.com/watch?v=gq1s8vJb_qc

when i use the command i don't realize that the %1 is expanded in a strange way and the url is truncated after = sign

if i use the same command from the normal shell everything work fine! thank you very much.. i will investigate more on this behavior
