Overview

Ruby Client for Cloud Video Intelligence API (GA)

Cloud Video Intelligence API: Detects objects, explicit content, and scene changes in videos. It also specifies the region for annotation and transcribes speech to text. Supports both asynchronous API and streaming API.

Quick Start

In order to use this library, you first need to go through the following steps:

  1. Select or create a Cloud Platform project.
  2. Enable billing for your project.
  3. Enable the Cloud Video Intelligence API.
  4. Setup Authentication.

Installation

$ gem install google-cloud-video_intelligence

Preview

VideoIntelligenceServiceClient

require "google/cloud/video_intelligence"

video_intelligence_client = Google::Cloud::VideoIntelligence.new
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(features, input_uri: input_uri) 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!

Next Steps

Enabling Logging

To enable logging for this library, set the logger for the underlying gRPC library. The logger that you set may be a Ruby stdlib Logger as shown below, or a Google::Cloud::Logging::Logger that will write logs to Stackdriver Logging. See grpc/logconfig.rb and the gRPC spec_helper.rb for additional information.

Configuring a Ruby stdlib logger:

require "logger"

module MyLogger
  LOGGER = Logger.new $stderr, level: Logger::WARN
  def logger
    LOGGER
  end
end

# Define a gRPC module-level logger method before grpc/logconfig.rb loads.
module GRPC
  extend MyLogger
end

Class Method Details

.new(version: , credentials: , scopes: , client_config: , timeout: ) ⇒ Object

Service that implements Google Cloud Video Intelligence API.

Parameters:

  • credentials (Google::Auth::Credentials, String, Hash, GRPC::Core::Channel, GRPC::Core::ChannelCredentials, Proc) (defaults to: )

    Provides the means for authenticating requests made by the client. This parameter can be many types. A Google::Auth::Credentials uses a the properties of its represented keyfile for authenticating requests made by this client. A String will be treated as the path to the keyfile to be used for the construction of credentials for this client. A Hash will be treated as the contents of a keyfile to be used for the construction of credentials for this client. A GRPC::Core::Channel will be used to make calls through. A GRPC::Core::ChannelCredentials for the setting up the RPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. A Proc will be used as an updater_proc for the Grpc channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

  • scopes (Array<String>) (defaults to: )

    The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

  • client_config (Hash) (defaults to: )

    A Hash for call options for each method. See Google::Gax#construct_settings for the structure of this data. Falls back to the default config if not specified or the specified config is missing data points.

  • timeout (Numeric) (defaults to: )

    The default timeout, in seconds, for calls made through this client.

  • metadata (Hash)

    Default metadata to be sent with each request. This can be overridden on a per call basis.

  • service_address (String)

    Override for the service hostname, or nil to leave as the default.

  • service_port (Integer)

    Override for the service port, or nil to leave as the default.

  • exception_transformer (Proc)

    An optional proc that intercepts any exceptions raised during an API call to inject custom error handling.

Parameters:

  • version (Symbol, String) (defaults to: :v1)

    The major version of the service to be used. By default :v1 is used.
