# CrunchyRoll.js

CrunchyRoll.js is capable of downloading anime from the popular CrunchyRoll streaming site.
|
|
||||||
|
CrunchyRoll.js is capable of downloading anime from the popular CrunchyRoll
|
||||||
|
streaming site. Each episode is stored with the original video encoding
|
||||||
|
(usually H.264, MP4) and the configured subtitle format (ASS or SRT). The two
|
||||||
|
output files can optionally be muxed into a single MKV file.
|
||||||
|
|
||||||
|
## Motivation
|
||||||
|
|
||||||
|
I **love** *CrunchyRoll*. They have been working hard to provide an amazing service to
|
||||||
|
*anime* fans and provide the *absolute best* way to watch *anime* series in a legal
|
||||||
|
way. As they offer a streaming service, they do not offer files to be downloaded
|
||||||
|
and enjoyed while offline (or travelling). This is understandable from a
|
||||||
|
business perspective, but extremely annoying for the end-user. I put this
|
||||||
|
application together to enable the files to be stored and enjoyed while offline.
|
||||||
|
Please do not download as much as you can and stop your premium subscription;
|
||||||
|
without our financial support, they cannot give us such as great service!
|
||||||
|
**Do not share downloaded files and delete them if you ever stop your
|
||||||
|
premium subscription!**
|
||||||
|
|
||||||
|
## Status
|
||||||
|
|
||||||
|
### Implemented
|
||||||
|
|
||||||
|
* Subtitle decoding.
|
||||||
|
* Subtitle converter for SRT subtitle output.
|
||||||
|
* Video streaming.
|
||||||
|
* Episode page scraping with subtitle saving and video streaming.
|
||||||
|
|
||||||
|
### Pending Implementation
|
||||||
|
|
||||||
|
* Detect and write the appropriate video extension (instead of hard-code mp4).
|
||||||
|
* Improve SRT support for i, b and u.
|
||||||
|
* Add ASS support.
|
||||||
|
* Add muxing (MP4+ASS=MKV).
|
||||||
|
* Add series API to download an entire series rather than per-episode.
|
||||||
|
* Add batch-mode to queue a bunch of series and do incremental downloads.
|
||||||
|
* Add authentication to the entire stack to support premium content.
|
||||||
|
* Add CLI interface with all the options.
|
||||||
|
* Enjoy beautiful anime series from disk when internet is down.
|
||||||
|
|
||||||
