TranscoderServiceClient

TranscoderServiceClient

Using the Transcoder API, you can queue asynchronous jobs for transcoding media into various output formats. Output formats may include different streaming standards such as HTTP Live Streaming (HLS) and Dynamic Adaptive Streaming over HTTP (DASH). You can also customize jobs using advanced features such as Digital Rights Management (DRM), audio equalization, content concatenation, and digital ad-stitch ready content generation.

Constructor

new TranscoderServiceClient(optionsopt, gaxInstanceopt)

Construct an instance of TranscoderServiceClient.

Parameters:
Name Type Attributes Description
options object <optional>

The configuration object. The options accepted by the constructor are described in detail in this document. The common options are:

Properties
Name Type Attributes Description
credentials object <optional>

Credentials object.

Properties
Name Type Attributes Description
client_email string <optional>
private_key string <optional>
email string <optional>

Account email address. Required when using a .pem or .p12 keyFilename.
keyFilename string <optional>

Full path to the a .json, .pem, or .p12 key downloaded from the Google Developers Console. If you provide a path to a JSON file, the projectId option below is not necessary. NOTE: .pem and .p12 require you to specify options.email as well.
port number <optional>

The port on which to connect to the remote host.
projectId string <optional>

The project ID from the Google Developer's Console, e.g. 'grape-spaceship-123'. We will also check the environment variable GCLOUD_PROJECT for your project ID. If your app is running in an environment which supports Application Default Credentials, your project ID will be detected automatically.
apiEndpoint string <optional>

The domain name of the API remote host.
clientConfig gax.ClientConfig <optional>

Client configuration override. Follows the structure of gapicConfig.
fallback boolean <optional>

Use HTTP/1.1 REST mode. For more information, please check the documentation.
gaxInstance gax <optional>

loaded instance of google-gax. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new TranscoderServiceClient({fallback: true}, gax);

Members

apiEndpoint

The DNS address for this API service - same as servicePath(), exists for compatibility reasons.

port

The port for this API service.

scopes

The scopes needed to make gRPC calls for every method defined in this service.

servicePath

The DNS address for this API service.

Methods

close() → {Promise}

Terminate the gRPC channel and close the client.

The client will no longer be usable and all future behavior is undefined.

Returns:
Type Description
Promise

A promise that resolves when the client is closed.

getProjectId() → {Promise}

Return the project ID used by this class.

Returns:
Type Description
Promise

A promise that resolves to string containing the project ID.

initialize() → {Promise}

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client. This function will be called automatically when any class method is called for the first time, but if you need to initialize it before calling an actual method, feel free to call initialize() directly.

You can await on this method if you want to make sure the client is initialized.

Returns:
Type Description
Promise

A promise that resolves to an authenticated service stub.

jobPath(project, location, job) → {string}

Return a fully-qualified job resource name string.

Parameters:
Name Type Description
project string
location string
job string
Returns:
Type Description
string

Resource name string.

jobTemplatePath(project, location, job_template) → {string}

Return a fully-qualified jobTemplate resource name string.

Parameters:
Name Type Description
project string
location string
job_template string
Returns:
Type Description
string

Resource name string.

listJobTemplatesAsync(request, optionsopt) → {Object}

Equivalent to listJobTemplates, but returns an iterable object.

for-await-of syntax is used with the iterable to get response elements on-demand.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Description
parent string

Required. The parent location from which to retrieve the collection of job templates. Format: projects/{project}/locations/{location}
pageSize number

The maximum number of items to return.
pageToken string

The next_page_token value returned from a previous List request, if any.
filter string

The filter expression, following the syntax outlined in https://google.aip.dev/160.
orderBy string

One or more fields to compare and use to sort the output. See https://google.aip.dev/132#ordering.
options object <optional>

Call options. See CallOptions for more details.
Returns:
Type Description
Object

An iterable Object that allows async iteration. When you iterate the returned iterable, each element will be an object representing JobTemplate. The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the documentation for more details and examples.
Example
  /**
   * 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.
   * TODO(developer): Uncomment these variables before running the sample.
   */
  /**
   *  Required. The parent location from which to retrieve the collection of job
   *  templates. Format: `projects/{project}/locations/{location}`
   */
  // const parent = 'abc123'
  /**
   *  The maximum number of items to return.
   */
  // const pageSize = 1234
  /**
   *  The `next_page_token` value returned from a previous List request, if
   *  any.

  /**

   *  See https://google.aip.dev/132#ordering.
   */
  // const orderBy = 'abc123'

  // Imports the Transcoder library
  const {TranscoderServiceClient} = require('@google-cloud/video-transcoder').v1;

  // Instantiates a client
  const transcoderClient = new TranscoderServiceClient();

  async function callListJobTemplates() {
    // Construct request
    const request = {
      parent,
    };

    // Run request
    const iterable = await transcoderClient.listJobTemplatesAsync(request);
    for await (const response of iterable) {
        console.log(response);
    }
  }

  callListJobTemplates();

listJobTemplatesStream(request, optionsopt) → {Stream}

Please see the documentation for more details and examples.
