I thought I would share the part of my twitterbrite scripts that uploads videos to Youtube. Its about 30 lines long, and took me an hour or so to write. Most of my time was spent figuring out form fields to fill out rather than writing code though….

I’ve broken the script down to three parts: logging in, setting the video attributes, and uploading the video file.

Login

page.form(’loginForm’) { |f| f.username = ‘username’ f.password = ‘password’ }.submit

<h3>Step 2: Setting video attributes</h3>
This is probably the most difficult step.  Now that the agent is logged in, we have to fetch the upload page and fill out the video attributes form.  You have to set the title, description, category, and keywords for your video.  The you have to tell the agent to click a special button.
```ruby
# Set the video attributes
page = agent.get('http://youtube.com/my_videos_upload')
form = page.form('theForm')
form.field_myvideo_title = 'My video title'
form.field_myvideo_descr = "My video description"
form.field_myvideo_categories = 28
form.field_myvideo_keywords = 'my tag'
page = form.submit(form.buttons.name('action_upload').first)

The number “28” is just the value from the category drop down list. You can iterate over the select options using mechanize, but I leave that as an exercise to the reader.

There you go. Upload lots of videos now! Yay!
