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.
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!
Open an issue or e-mail me directly. I’d be happy to answer your questions.
