No format stream map found - was the video id correct?July 20
collee1988Yes, the system is not working!
In my case, only Music Videos, or protected videos are not downloading.
I think Youtube has updated their system and it is not only a Cipher Signature issue this time.
Hope you can fix soon!
In some web search I could see that others Youtube downloader system are not working too.
So the update was general on Youtube.
collee1988Do not work, as a rule, old videos that 3 years or more
