/**
 * Service Description: 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.
 *
 * 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:
 *
 * ```
 * $transcoderServiceClient = new TranscoderServiceClient();
 * try {
 *     $formattedParent = $transcoderServiceClient->locationName('[PROJECT]', '[LOCATION]');
 *     $job = new Job();
 *     $response = $transcoderServiceClient->createJob($formattedParent, $job);
 * } finally {
 *     $transcoderServiceClient->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.
