Creating a Transcoding Task

You can create a transcoding task by creating an MPC client instance and configuring related parameters.

Core Code

  1. Create an MPC client instance.

    public static MpcClient initMpcClient() {
    // Set httpConfig.
    HttpConfig httpConfig = HttpConfig.getDefaultHttpConfig().withIgnoreSSLVerification(true).withTimeout(3);
    // Set the HTTP proxy as required.
    //httpConfig.withProxyHost("xxxxxx").withProxyPort(xxxxxx).withProxyUsername("xxxxxx").
            //withProxyPassword("xxxxxx");
    // Enter the AK and SK. To view your AK and SK, choose My CredentialsAccess Keys under your account on the console.
    String ak = "xxxxxx";
    String sk = "xxxxxx";
        // Enter the project ID. To view your project ID, choose My CredentialsAPI Credentials under your account on the console.
    String projectId = "xxxxxx";
    // Enter the endpoint. The following uses region01 as an example.
    String endpoint = "https://mpc.region01.myhuaweicloud.com";
    BasicCredentials auth = new BasicCredentials().withAk(ak).withSk(sk).withProjectId(projectId);
    return MpcClient.newBuilder()
            .withHttpConfig(httpConfig)
            .withCredential(auth)
            .withEndpoint(endpoint)
            .build();
}
  2. Create a transcoding request and set the request body.
    A transcoding request includes information about an input file and output file, and transcoding template settings. For details about the parameters, see Creating a Transcoding Task.

    // Set the input file path.
ObsObjInfo input = new ObsObjInfo()
    // Set the bucket name.
    .withBucket("mpc-east-2")
    // Set the region where the OBS bucket is located.
    .withLocation("region01")
    // Set the input file object.
    .withObject("input/ok.mp4");
// Set the output file path.
ObsObjInfo output = new ObsObjInfo().withBucket("mpc-east-2").withLocation("region01")
        // Set the output file path.
        .withObject("output");
// Create a transcoding request.
CreateTranscodingTaskRequest request
        = new CreateTranscodingTaskRequest().withBody(new CreateTranscodingReq()
        .withInput(input)
        .withOutput(output)
        // Configure a transcoding template. To view IDs of system templates, choose Global SettingsSystem Templates on the MPC console.
        .withTransTemplateId(Collections.singletonList(7000530))
        // Set output file names. Each template has a name.
        .withOutputFilenames(Collections.singletonList("output_"))
        // Configure snapshot parameters and fill in the thumbnail structure as required.
        //.withThumbnail(new Thumbnail())
        // Configure encryption parameters and fill in the encryption structure as required.
        //.withEncryption(new Encryption())
);
  3. Send the transcoding request.

    // Send the transcoding request.
CreateTranscodingTaskResponse response = initMpcClient().createTranscodingTask(request);
// Return a message.
System.out.println("CreateTranscodingTaskResponse=" + response);
