Easiest way to post videos directly to S3? I am working on a video sharing site and I plan to use the Video module. Amazon S3 is also being used as the file system. The problem is how to override/extend it so the video file skips the intermediate step of uploading to the server and directly upload to S3 using a separate POST request?
If you're using Drupal 7, take a look at these two projects:


Storage API
Amazon S3


Both of these let you store file uploads on S3 instead of the local filesystem.
