Youtube Uploader?

Try using googlecl

sudo apt-get install googlcl

this tool provides a user-friendly command-line interface to some of the Google Data Protocol (gdata) APIs.

You can nicely upload a video to YouTube from the command line with the command:

google youtube post --category Education --devtags GoogleCL test.mp4

This will upload the video test.mp4 to your YouTube (the one you granted GoogleCL access to) account, in the Education category. This is a simple test, so check this useful guide.
