I have been written programs handle video streams. There is many kinds of video services (ustream, YouTube, etc.). So I tought that the library handle easily these streams without care kind of service is useful. Sure, it is already exists.
The program can be used from CLI. It is made by Python, so it can be used as Python libraries. Probably It works on windows (Not checked yet). Great.
It supports about 25 services. Niconico douga (Japanese famous video service) is not supported. Inevitable.
