How can I play an already uploaded video inside an Amazon S3 bucket? And how can I use the String Authentication on it? I´m new with video module, and with Amazon S3.
I need a video (that I´ve already uploaded to an Amazon S3 bucket), to be able to be played inside my site. I don´t want to upload it again through Drupal.

This video needs to be private. I´ve read something about "S3 Query String Authentication" but didn´t get how to actually implement that in my site.

I´m not able to point to a video that´s already uploaded to a bucket. I can only upload through Drupal, or upload it to a folder inside my drupal installation. How can I just grab the video?

And Should I do that using string authentication? How can I avoid people that´s not logged in to see or link to the video? (I know that there´s no way to stop other people to copy your stuff, but I´ve read about hot links and would like to avoid that from happening if I can).

I need that video to be available for a long period of time for my users, I just don´t want them to post the link in other sites (and use my bandwith).

I´m pretty clueless. Please I would love some help if you can. Thanks!!!!

I'm answering this, hoping I can help anyone else with the same problem.
If you're trying to play videos already uploaded to your S3 Amazon account, you won't find an appropriate Drupal Module to do so. (see this).
What I did is to get myself an Amazon Cloudfront account and protect the videos manually with an expiration date; then I pasted the video (using the player jwplayer), and I controlled the access to that node using any of the node access modules.
