Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new StreamingVideoIntelligenceService client object.

Examples:


# Create a client using the default configuration
client = ::Google::Cloud::VideoIntelligence::V1p3beta1::StreamingVideoIntelligenceService::Client.new

# Create a client using a custom configuration
client = ::Google::Cloud::VideoIntelligence::V1p3beta1::StreamingVideoIntelligenceService::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the StreamingVideoIntelligenceService client.

Class Method Details

.configure {|config| ... } ⇒ Client::Configuration

Configure the StreamingVideoIntelligenceService Client class.

See Configuration for a description of the configuration fields.

Examples:


# Modify the configuration for all StreamingVideoIntelligenceService clients
::Google::Cloud::VideoIntelligence::V1p3beta1::StreamingVideoIntelligenceService::Client.configure do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the Client client.

Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the StreamingVideoIntelligenceService Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

Yield Parameters:

Returns:

#streaming_annotate_video(request, options = nil) {|response, operation| ... } ⇒ ::Enumerable<::Google::Cloud::VideoIntelligence::V1p3beta1::StreamingAnnotateVideoResponse>

Performs video annotation with bidirectional streaming: emitting results while sending video/audio bytes. This method is only available via the gRPC API (not REST).

Examples:

Basic example

require "google/cloud/video_intelligence/v1p3beta1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::VideoIntelligence::V1p3beta1::StreamingVideoIntelligenceService::Client.new

# Create an input stream.
input = Gapic::StreamInput.new

# Call the streaming_annotate_video method to start streaming.
output = client.streaming_annotate_video input

# Send requests on the stream. For each request object, set fields by
# passing keyword arguments. Be sure to close the stream when done.
input << Google::Cloud::VideoIntelligence::V1p3beta1::StreamingAnnotateVideoRequest.new
input << Google::Cloud::VideoIntelligence::V1p3beta1::StreamingAnnotateVideoRequest.new
input.close

# The returned object is a streamed enumerable yielding elements of type
# ::Google::Cloud::VideoIntelligence::V1p3beta1::StreamingAnnotateVideoResponse
output.each do |current_response|
  p current_response
end

Parameters:

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
