Video Download Library.
Support for Youtube, Vimeo. Multithread downloads. Based on multithread download library https://github.com/axet/wget.
Pure java!
How this library works: YouTube.md
Here are a two kind of exceptions.
-
Fatal exception. all RuntimeException's We shall stop application
-
DownloadError (extends RuntimeException) We unable to process following url and shall stop to download it
