Crunchyroll Downloader

Downloads anime from Crunchyroll and outputs them in a MKV file.

You won't be banned or anything, I downloaded all Kaguya-Sama seasons to test during 30 mins and everything went fine

Features

• Supports choosing the audio and subtitles language, including downloading multiple of each into a single file
• Supports choosing the audio and video quality
• Decrypts Widevine DRM (requires: a .wvd file or client_id.bin and private_key.pem files)
• Adds metadata (like episode name) to the MKV container
• Parallel segment downloads (10 workers) for faster downloads
• Retry with backoff on connection errors
• Batch download from a list of URLs

Requirements

• FFmpeg
• To download Premium-only content, a Crunchyroll Premium account. No, this can't be bypassed and a free trial should be enough
• Either a .wvd file, or a client_id.bin and private_key.pem

Help

How do I get my etp_rt cookie?

• Go to https://crunchyroll.com
• Open Developer Tools
• Firefox: Go to Storage then Cookies
  Chrome: Go to Application then Cookies
• Select the Crunchyroll domain, then copy the etp_rt cookie value

What is a .wvd file and do I really need one?

Yes, Crunchyroll uses DRM-only content. This file is used to get a Widevine license, which gives the keys to decrypt the media.

If you don't have a rooted Android device or are just lazy, search "ready to use cdms" and you'll find plenty of websites providing those files.
