AWS C++ SDK GetMedia call with Live KVS stream

I am currently working on implementing a C++ project to retrieve the most up to date fragment from a Live KVS Stream using GetMedia. However whenever GetMedia is called, the program will currently hang at that point until the stream has been stopped, only after this will the GetMedia call return some data.

My question is: Is there a way to retrieve the latest fragment in a stream using GetMedia, while the stream is active and live streaming from a Pi 4. Without having to stop the stream?

My Current Code is the following, please let me know if there is anything I am missing or ways I could improve or solve this issue

    options.loggingOptions.logLevel = Aws::Utils::Logging::LogLevel::Info;

        aws_credentials.SetAWSAccessKeyId("MY_ACCESS_KEY");

        Aws::Auth::SimpleAWSCredentialsProvider provider = Aws::Auth::SimpleAWSCredentialsProvider(aws_credentials);

        selector.WithStartSelectorType(Aws::KinesisVideoMedia::Model::StartSelectorType::NOW);
        getMediaRequest.SetStartSelector(selector);

        videoMediaClient->OverrideEndpoint(result.GetResultWithOwnership().GetDataEndpoint());
        videoMediaClient->EnableRequestProcessing();
        videoMediaClient->SetServiceClientName("kinesisvideo");

        Aws::KinesisVideoMedia::Model::GetMediaOutcome outcome = client->GetMedia(request);
        if (outcome.IsSuccess()) {
            cout << "Success" << endl;
            char buffer[1024];
            outcome.GetResultWithOwnership().GetPayload().read(buffer, 1024);
            cout << buffer<< endl;
        } else {
            cout << "Failure" << endl;
        }
    }
