[iqiyi]something wrong with vip video

[Lua12138]

when I try to download some VIP videos, I got the message WARNING: unable to log in: please login via the web interface and enter the CAPTCHA code, and I try to login in with web but no CAPTCHA.(before the video, I have already download 2 VIP videos.)
I guess, the IQIYI may be check the interval of login, because there are many block a video. and a download URL only has 20 minutes. so I have to login many times to download a video.

youtube-dl should handle CAPTCHA gracefully. See #154. Current workaround is using --cookies. For example: (cookie.txt will be created automatically)

$ youtube-dl --cookies cookie.txt --username user@example.com --password some_password http://www.iqiyi.com/v_19rrny4w8w.html -vF
