Instance Method Details

#annotate_video(input_uri: nil, input_content: nil, features: nil, video_context: nil, output_uri: nil, location_id: nil, options: nil) ⇒ Google::Gax::Operation

Performs asynchronous video annotation. Progress and results can be retrieved through the google.longrunning.Operations interface. Operation.metadata contains AnnotateVideoProgress (progress). Operation.response contains AnnotateVideoResponse (results).

Examples:

require "google/cloud/video_intelligence"

video_intelligence_client = Google::Cloud::VideoIntelligence.new(version: :v1beta2)
input_uri = "gs://cloud-samples-data/video/cat.mp4"
features_element = :LABEL_DETECTION
features = [features_element]

# Register a callback during the method call.
operation = video_intelligence_client.annotate_video(input_uri: input_uri, features: features) do |op|
  raise op.results.message if op.error?
  op_results = op.results
  # Process the results.

  metadata = op.metadata
  # Process the metadata.
end

# Or use the return value to register a callback.
operation.on_done do |op|
  raise op.results.message if op.error?
  op_results = op.results
  # Process the results.

  metadata = op.metadata
  # Process the metadata.
end

# Manually reload the operation.
operation.reload!

# Or block until the operation completes, triggering callbacks on
# completion.
operation.wait_until_done!

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.
