Google Cloud Video Live Stream V1 Client - Class LivestreamServiceClient (0.2.6)

Reference documentation and code samples for the Google Cloud Video Live Stream V1 Client class LivestreamServiceClient.

Service Description: Using Live Stream API, you can generate live streams in the various renditions and streaming formats. The streaming format include HTTP Live Streaming (HLS) and Dynamic Adaptive Streaming over HTTP (DASH). You can send a source stream in the various ways, including Real-Time Messaging Protocol (RTMP) and Secure Reliable Transport (SRT).

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

$livestreamServiceClient = new LivestreamServiceClient();
try {
    $formattedParent = $livestreamServiceClient->locationName('[PROJECT]', '[LOCATION]');
    $channel = new Channel();
    $channelId = 'channel_id';
    $operationResponse = $livestreamServiceClient->createChannel($formattedParent, $channel, $channelId);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $livestreamServiceClient->createChannel($formattedParent, $channel, $channelId);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $livestreamServiceClient->resumeOperation($operationName, 'createChannel');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $livestreamServiceClient->close();
}

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

Methods

channelName

Formats a string containing the fully-qualified path to represent a channel resource.

Parameters
Name	Description
`project`	`string`
`location`	`string`
`channel`	`string`

Returns
Type	Description
`string`	The formatted channel resource.

eventName

Formats a string containing the fully-qualified path to represent a event resource.

`project`	`string`
`location`	`string`
`channel`	`string`
`event`	`string`

Returns
Type	Description
`string`	The formatted event resource.

inputName

Formats a string containing the fully-qualified path to represent a input resource.

Parameters
Name	Description
`project`	`string`
`location`	`string`
`input`	`string`

Returns
Type	Description
`string`	The formatted input resource.

locationName

Formats a string containing the fully-qualified path to represent a location resource.

Parameters
Name	Description
`project`	`string`
`location`	`string`

Returns
Type	Description
`string`	The formatted location resource.

parseName

Parses a formatted name string and returns an associative array of the components in the name.

The following name formats are supported: Template: Pattern

channel: projects/{project}/locations/{location}/channels/{channel}
event: projects/{project}/locations/{location}/channels/{channel}/events/{event}
input: projects/{project}/locations/{location}/inputs/{input}
location: projects/{project}/locations/{location}

The optional $template argument can be supplied to specify a particular pattern, and must match one of the templates listed above. If no $template argument is provided, or if the $template argument does not match one of the templates listed, then parseName will check each of the supported templates, and return the first match.

__construct

Constructor.

Parameters
Name	Description
`options`	`array` Optional. Options for configuring the service API wrapper.
`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.
`↳ clientCertSource`	`callable` A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.

createChannel

Creates a channel with the provided unique ID in the specified region.

Parameters
Name	Description
`parent`	`string` Required. The parent location for the resource, in the form of: `projects/{project}/locations/{location}`.
`channel`	`Google\Cloud\Video\LiveStream\V1\Channel` Required. The channel resource to be created.
`channelId`	`string` Required. The ID of the channel resource to be created. This value must be 1-63 characters, begin and end with `[a-z0-9]`, could contain dashes (-) in between.
`optionalArgs`	`array` Optional.
`↳ requestId`	`string` A request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. The server will guarantee that for at least 60 minutes since the first request. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported `(00000000-0000-0000-0000-000000000000)`.

Parameters
Name	Description
`name`	`string` Required. The name of the channel resource, in the form of: `projects/{project}/locations/{location}/channels/{channelId}`.
`optionalArgs`	`array` Optional.
`↳ requestId`	`string` A request ID to identify requests.

The server will guarantee that for at least 60 minutes since the first request. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported `(00000000-0000-0000-0000-000000000000)`.

You can only update the following fields: * `preprocessingConfig` * `securityRules` The fields specified in the update_mask are relative to the resource, not the full request. A field will be overwritten if it is in the mask.
`↳ requestId`	`string` A request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. The server will guarantee that for at least 60 minutes since the first request. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported `(00000000-0000-0000-0000-000000000000)`.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.
