Transcoder API C++ Client Library
An idiomatic C++ client library for video services, including:
- Live Stream API, a service to transcode live, linear video streams into a variety of formats.
- Transcoder API, a service to convert video files into formats suitable for consumer distribution.
- Video Stitcher API, a service to generate dynamic content for delivery to client devices. Call the Video Stitcher API from your servers to dynamically insert ads into video-on-demand and live streams for your users.
While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.
Quickstart
The following shows the code that you'll run in the google/cloud/video/quickstart/
directory, which should give you a taste of the Transcoder API C++ client library API.
#include "google/cloud/video/transcoder/v1/transcoder_client.h"
#include <iostream>
int main(int argc, char* argv[]) try {
if (argc != 3) {
std::cerr << "Usage: " << argv[0] << " project-id location-id\n";
return 1;
}
namespace transcoder = ::google::cloud::video_transcoder_v1;
auto client = transcoder::TranscoderServiceClient(
transcoder::MakeTranscoderServiceConnection());
auto const parent =
std::string{"projects/"} + argv[1] + "/locations/" + argv[2];
for (auto r : client.ListJobs(parent)) {
if (!r) throw std::move(r).status();
std::cout << r->DebugString() << "\n";
}
return 0;
} catch (google::cloud::Status const& status) {
std::cerr << "google::cloud::Status thrown: " << status << "\n";
return 1;
}
Main classes
This library offers multiple *Client
classes, which are listed below. Each one of these classes exposes all the RPCs for a gRPC service
as member functions of the class. This library groups multiple gRPC services because they are part of the same product or are often used together. A typical example may be the administrative and data plane operations for a single product.
The library also has other classes that provide helpers, configuration parameters, and infrastructure to mock the *Client
classes when testing your application.
video_livestream_v1::LivestreamServiceClient
video_stitcher_v1::VideoStitcherServiceClient
video_transcoder_v1::TranscoderServiceClient
Retry, Backoff, and Idempotency Policies.
The library automatically retries requests that fail with transient errors, and uses exponential backoff to backoff between retries. Application developers can override the default policies.
