Niconico-Video-Downloader

The coolest project I wrote that use selenium, youtube-dl to fetch videos list from niconico account favourite list and download these videos.

About this project

The project is no longer maintained.
The project is not working any more in 2020 as NicoNico completely remade their user pages, which breaks Selenium code from fetching the favourite list contents.
A solution is possible, but I won't do it anymore

Alternates to this project

If you still want to batch download videos from niconico account favourite list, consider using any programs from the list of Awesome NicoNicoDouga Video Downloaders.

This list will be maintained in long term.

Appreciation

Special thanks for the 3rd party programable video downloader------Youtube-dl, without this excutable file, I can't fix the issue that happened after the niconico website updates. Youtube-dl: https://github.com/rg3/youtube-dl/

Thanks for Selenium, without this amazing library, I can't come up with this project. Selenium: https://www.seleniumhq.org/

And also thanks for the ChromeDriver that provided by Google ChromeDriver: https://sites.google.com/a/chromium.org/chromedriver/

Currently this project only supports Windows and only support GoogleChrome, since I only use them

How to use

Prerequisite:

• Windows OS
• Java 11
• Chrome browser

Step to setup

• download the artifact from release pages, unpack it
• create your own profile: go to the data/ folder, create an copy of example_user.properties, and fill in that property file.
  • modify the data.downloadedList to something else to avoid using the prefilled download.txt in data/
• modify system_config.property
  • modify user.config to use your own profile
  • modify idm property valye if you plan to use IDM to download PVs (which means you set downloadMethod to "idm")
• (optional, recommended) update youtube-dl.exe in lib/ with command 'youtube-dl.exe --update'
• run: open terminal in the project root folder, type java -jar .\<the jar filename>

Known Issue:

• recent Chrome 80 webdriver would flash timeout warning and occasionally throw ConnectException, if that happens, simply clean out all Runtime Broker in Windows Task Manager, clean up chromedriver.exe, and restart the program.
