title: Can video-intelligence-api send the output to a pub/sub topic
body: <p>Is it possible to have the Video Intelligence API respond on a pub/sub topic? It makes no sense to have a cloud function (or something else) waiting for minutes until the video processing operation completes.</p>
  
  <p>The documentation says you can specify an output_uri for the bucket location and have a topic on that specific bucket, but that may add extra delay.
  Also the longrunning package mentions something generic on managing operations on Pub/Sub.</p>
  
  <p>Thanks,</p>
