Description of your issue, suggested solution and other information

I tried to download a video from NicoVideo but it's unable to find video file.

[yan12125]

In Firefox NicoNico says:

Unable to play video.

This video is not available in your country.

Which country are you in?

[antonio8909]

@yan12125 I tried from almost all countries and I can't still access to the video. In Spain it says that it's geoblocked but if I connect with a Japanese Proxy it says
[niconico] 1490345969: Downloading flv info
ERROR: Unable to find video URL

[yan12125]

I guess the video is broken and no one can access it. If you know a way to get the video working (in browsers, other downloaders, etc.), feel free to leave a comment below and I'll reopen this ticket.

[antonio8909]

I dont think the video is broken...

[yan12125]

Can you watch the video in browsers with a Japan proxy?

[siddht4]

it works an account is needed but oauth is supported.

[yan12125]

After finding a working Japan proxy and choose Japanese as the language and Japan as the region on its website, I got this:

The highlighted text is:

この動画は有料です

Google translate says:

This video is charged

Yes it's not broken but requires an account that has paid. @antonio8909 Did you use a correct account?

[siddht4]

yes same here, they are using `

try {

  | window.NicoGoogleTagManagerDataLayer = [];
  |  
  | var data = {};
  |  
  | data.user = (function() {
  | var user = {};
  |  
  | user.user_id = parseInt('', 10) || null;
  | user.login_status = 'login';
  | user.member_status = 'normal';
  | user.birthday = '';
  | user.sex = 'male';
  | user.country = 'Japan';
  | user.prefecture = '神奈川県';
  | user.ui_area = 'tw';
  | user.ui_lang = 'en-us';
  |  
  |  
  | return user;
  | })();
  |  
  | window.NicoGoogleTagManagerDataLayer.push(data);
  | } catch(e) {}

`

this javascript + the actual ip to detect it. paid account needed too. whats the manga or anime all about ?

[antonio8909]

If they need a paid account, why is the player working and you can see the seconds passing?

[siddht4]

If they need a paid account, why is the player working

@antonio8909 that video is chargeable, the player isn`t initialized its just its thumbnail shown.Every video site does that gernerate some screenshot from the video and is shown.

you can see the seconds passing

its to let you 100 % make sure the video is loaded,if it fails exception would arise and then its a developer faults.It also says just pay the amount and watch the video as soon as payment is verified,no more delays,no need to generate url or seesion for the particular video,

[antonio8909]

It's rare that they let you see seconds passing and no the video. It's so strange.
I'll keep searching for more info
