Download recently released Nico Nico video
I can do it,
Niconico videos posted in the past can not be downloaded
Maybe the recently published Nico Nico video may be a new way to re-encode 1.5 GB
A new scheme of 1.5 GB re-encoding
Nico Nico Douga is compatible with downloads
Niconico's videos recently posted,
The recently published Nico Nico video is different from the 1.5 GB re-encoding method
In old-fashioned old style,
Older old system Nico Nico Douga does not support downloading
