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.
