Is it still support download videos from nicovideo.jp?

[Cupcake-iOS]

I try to download the video file from nicovideo.jp, but it's not work.
So is it still support download videos from nicovideo.jp?

I'm using version 2015.06.15.
And download url is http://www.nicovideo.jp/watch/sm26509498

The error message is

Could you add the option --write-pages like the command above and upload/paste all *.dump files?

It's really strange~~
here is my dump files

[yan12125]

There's something strange in sm26509498_http_-_ext.nicovideo.jp_thumb_watch.dump:

errno=17&error=invalid_play_key&done=true

The play key is from sm26509498_http_-_ext.nicovideo.jp_thumb_watch_sm26509498.dump:

,'thumbPlayKey': '1434636487.0.1.sklvT3aSc_7YI9KJ9W4YUJVVy6k...'

I got the same error with this key, and I don't know why niconico gives the wrong key.

As a workaround, could you try to download with --username and --password options?

[Cupcake-iOS]

I try to download with --username and --password.
I don't know is it ok to use Facebook authentication, but the same result, which is

This affects me as well, with v2016/03/26. Here's yet another examples that youtube-dl failed. (I was opening the issue when I found this, so I'll c&p what I was writing here)

---

So I heard youtube-dl can download from nicovideo, I picked this video for testing, but failed. I tried another, but this didn't work either.
I can't test for every single video on there, but looks like nicovideo functionality is dead.

What happened

Failure while downloading the video on niconico. ExtractorError: Unable to find video URL has occurred.

Environment

Mac OS X 10.10.5
HomeBrew-downloaded youtube-dl v2016/03/26.
zsh 5.2 (x86_64-apple-darwin14.5.0)

Steps to reproduce

Try downloading any video on niconico. youtube-dl http://www.nicovideo.jp/watch/sm*****

Expected

Video downloaded to current directory.

Actual

youtube-dl failed with ExtractorError: Unable to find video URL.

Both work fine for me. Post the outputs with --dump-pages.

[Clpsplug]

OK, so I did --dump-pages, but the output was too large (and also they were in base64,) I decoded them and uploaded to my dropbox.

https://www.dropbox.com/s/benfcsmrms8qfjp/youtube-dl%20niconico%20fail.zip?dl=0

Looks like I've got the same issue here. I found errno=17&error=invalid_play_key&done=true in flv info.

Niconico now blocks playing without an account. Does the error occur with credentials?

Closing as no response for a long time.
