Documentation

Overview

Package videointelligence is an auto-generated package for the 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.

General documentation

For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go.

Example usage

To get started with this package, create a client.

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := videointelligence.NewClient(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client.

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := videointelligence.NewClient(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

req := &videointelligencepb.AnnotateVideoRequest{
	// TODO: Fill request struct fields.
	// See https://pkg.go.dev/cloud.google.com/go/videointelligence/apiv1/videointelligencepb#AnnotateVideoRequest.
}
op, err := c.AnnotateVideo(ctx, req)
if err != nil {
	// TODO: Handle error.
}

resp, err := op.Wait(ctx)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

Types

type AnnotateVideoOperation

type AnnotateVideoOperation struct {
	// contains filtered or unexported fields
}

AnnotateVideoOperation manages a long-running operation from AnnotateVideo.

func (*AnnotateVideoOperation) Done

func (op *AnnotateVideoOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*AnnotateVideoOperation) Metadata

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*AnnotateVideoOperation) Name

func (op *AnnotateVideoOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*AnnotateVideoOperation) Poll

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*AnnotateVideoOperation) Wait

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.

type CallOptions

type CallOptions struct {
	AnnotateVideo []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

type Client

type Client struct {

	// The call options for this service.
	CallOptions *CallOptions

	// LROClient is used internally to handle long-running operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.
	LROClient *lroauto.OperationsClient
	// contains filtered or unexported fields
}

Client is a client for interacting with Cloud Video Intelligence API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

Service that implements the Video Intelligence API.

func NewClient

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewClient creates a new video intelligence service client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

Service that implements the Video Intelligence API.

Example
package main

import (
	"context"

	videointelligence "cloud.google.com/go/videointelligence/apiv1"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := videointelligence.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}
Output:

func NewRESTClient added in v1.10.0

func NewRESTClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewRESTClient creates a new video intelligence service rest client.

Service that implements the Video Intelligence API.

Example
package main

import (
	"context"

	videointelligence "cloud.google.com/go/videointelligence/apiv1"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := videointelligence.NewRESTClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}
Output:

func (*Client) AnnotateVideo

AnnotateVideo 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).

Example
package main

import (
	"context"

	videointelligence "cloud.google.com/go/videointelligence/apiv1"
	videointelligencepb "cloud.google.com/go/videointelligence/apiv1/videointelligencepb"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := videointelligence.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &videointelligencepb.AnnotateVideoRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/cloud.google.com/go/videointelligence/apiv1/videointelligencepb#AnnotateVideoRequest.
	}
	op, err := c.AnnotateVideo(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}

	resp, err := op.Wait(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}
Output:

func (*Client) AnnotateVideoOperation

func (c *Client) AnnotateVideoOperation(name string) *AnnotateVideoOperation

AnnotateVideoOperation returns a new AnnotateVideoOperation from a given name. The name must be that of a previously created AnnotateVideoOperation, possibly from a different process.

func (*Client) Close

func (c *Client) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*Client) Connection deprecated

func (c *Client) Connection() *grpc.ClientConn

Connection returns a connection to the API service.

Deprecated: Connections are now pooled so this method does not always return the same resource.
