# This is an example how to transcode video using Transcoder API. 
#
# You need to set up an input bucket and an output bucket, and then grant
# service-[PROJECT_NUMBER}@gcp-sa-transcoder.iam.gserviceaccount.com 
# roles/storage.objectViewer on the input and output bucket, and also
# roles/storage.objectCreator on the output bucket.
