It seems that the API has changed – the That's in |

I've figured the issue out – apparently, Niconico have been recombobulating their API quite a bit lately, including switching from snake case to camel case. Here's a diff patch that makes videos of this type work: @@ -195,7 +195,7 @@

formats.append(self._extract_format_for_quality(
api_data, video_id, audio_quality, video_quality))I'm hesitant to make a pull request – as it stands, this almost certainly ruins the ability to download other types of videos (like FLV videos, for example). I'll leave the formal fix to someone who's more familiar with Niconico's inner workings. (Does the FLV video endpoint even still work? Does the “old HTML5 video” method still exist? From what I can tell in the API, it might be the case that the DMC approach is the only one at this point, although I may very well be wrong about that.) Here's the fix, either way! |

I'm 99.9% sure that FLV videos at least are entirely dead. 10+ year old videos are served as video/MP2T now when they were certainly flv at the time (this also goes for swf videos, which used to be interactive and now are not). I'd take most videos working over none, in any case, so I'll use this patch for now - thanks! |

Thanks for the patch! Required a bit more fixing though. |

Also getting this issue. |

Same error here |

For downloading nicovideo.jp, I recommend using one of the following alternatives (this list is copied from my another abandoned project readme file):
