1. Create AcsClient instance.
    $clientProfile = DefaultProfile::getProfile(
    $mps_region_id,                   # Your Region ID
    $access_key_id,                   # Your AccessKey ID
    $access_key_secret                # Your AccessKey Secret
    );
    $client = new DefaultAcsClient($clientProfile);
  2. Create request, and set parameters.
    $request = new Mts\SubmitJobsRequest();
    $request->setAcceptFormat('JSON');
  3. Transcoding parameters.
    • Input
      $input = array('Location' => $oss_location,
                      'Bucket' => $oss_bucket,
                      'Object' => urlencode($oss_input_object));
      $request->setInput(json_encode($input));
    • Output
      $output = array('OutputObject' => urlencode($oss_output_object));
      • Container
        $output['Container'] = array('Format' => 'mp4');
      • Video
        $output['Video'] = array('Codec' =>'H. 264',
                                    'Bitrate' => 1500,
                                    'Width' => 1280,
                                    'Fps' => 25);
      • Audio
        $output['Audio'] = array('Codec' => 'AAC',
                                    'Bitrate' => 128,
                                    'Channels' => 2,
                                    'Samplerate' => 44100);
      • TemplateId
        $output['TemplateId'] = $template_id;
    • PipelineId
      $request->setPipelineId($pipeline_id);
  4. Initiate API request and display returned value.
    $response = $client->getAcsResponse($request);
    print 'RequestId is:' . $response->{'RequestId'} . "\n";;
    if ($response->{'JobResultList'}->{'JobResult'}[0]->{'Success'}) {
    print 'JobId is:' .
          $response->{'JobResultList'}->{'JobResult'}[0]->{'Job'}->{'JobId'} . "\n";
    } else {
    print 'SubmitJobs Failed code:' .
          $response->{'JobResultList'}->{'JobResult'}[0]->{'Code'} .
          ' message:' .
          $response->{'JobResultList'}->{'JobResult'}[0]->{'Message'} . "\n";
    }
