Unfortunately, I'm not using this package anymore. Also, checking at [0]
looks it is not maintained anymore.
The package description is:
libquvi is a library to parse Adobe flash video download links. It
supports Youtube and other similar video websites. It provides access
to functionality and data through an API, and does not enable or
require the use of the flash technology.
.
This package contains the Lua scripts used to parse documents.
