Package videointelligence is an auto-generated package for the Google 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.
NOTE: This package is in beta. It is not stable, and may be subject to changes.
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.
For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go.
Functions
func DefaultAuthScopes
func DefaultAuthScopes() []string
DefaultAuthScopes reports the default set of authentication scopes to use with this package.
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
func (op *AnnotateVideoOperation) Metadata() (*videointelligencepb.AnnotateVideoProgress, error)
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
func (op *AnnotateVideoOperation) Poll(ctx context.Context, opts ...gax.CallOption) (*videointelligencepb.AnnotateVideoResponse, error)
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
func (op *AnnotateVideoOperation) Wait(ctx context.Context, opts ...gax.CallOption) (*videointelligencepb.AnnotateVideoResponse, error)
Wait blocks until the long-running operation is completed, returning the response and any errors encountered.
See documentation of Poll for error-handling information.
CallOptions
type CallOptions struct {
AnnotateVideo []gax.CallOption
}
CallOptions contains the retry settings for each method of Client.
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 Google Cloud Video Intelligence API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.
Service that implements Google Cloud Video Intelligence API.
func NewClient
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 Google Cloud Video Intelligence API.
Example
package main
import (
"context"
videointelligence "cloud.google.com/go/videointelligence/apiv1beta2"
)
func main() {
ctx := context.Background()
c, err := videointelligence.NewClient(ctx)
if err != nil {
// TODO: Handle error.
}
defer c.Close()
// TODO: Use client.
_ = c
}
func (*Client) AnnotateVideo
func (c *Client) AnnotateVideo(ctx context.Context, req *videointelligencepb.AnnotateVideoRequest, opts ...gax.CallOption) (*AnnotateVideoOperation, error)
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/apiv1beta2"
videointelligencepb "google.golang.org/genproto/googleapis/cloud/videointelligence/v1beta2"
)
func main() {
ctx := context.Background()
c, err := videointelligence.NewClient(ctx)
if err != nil {
// TODO: Handle error.
}
defer c.Close()
req := &videointelligencepb.AnnotateVideoRequest{
// TODO: Fill request struct fields.
}
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
}
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
Close closes the connection to the API service. The user should invoke this when the client is no longer required.
func (*Client) Connection
func (c *Client) Connection() *grpc.ClientConn
Connection returns a connection to the API service.
Deprecated.
