Description

Downloading long videos requires heartbeat signals. Here's the description found in the original issue on youtube-dl's repo:

As of today, Nicovideo's seem to implemented a new session system. After every few minutes, the url of the video changes. This causes a 403 Forbidden error on the old url, Causing the Downloader to fail.
A screenshot of part of a video session:
chrome 2017-10-25 10 43 35 396

Resuming the download works just for a few minutes before the session is dropped.
Note: I have only tested on a non-premium account. Im not sure if it applies to the permium accounts or not.
