转码 - 媒体处理

本文提供了Java SDK转码相关功能的API调用示例，包含提交转码作业、查询转码作业、取消转码作业和遍历转码作业。

前提条件

使用前请先初始化客户端，详细操作请参见初始化。

提交转码作业

调用SubmitJobs接口，完成提交转码作业。

说明

通过SDK提交转码作业时Object需经URLEncode，否则会导致转码失败。更多信息，请参见URL Encoding说明。
请按照规范填写文件名称，否则会找不到文件导致转码失败。详细名称规范，请参见参数详情。
建议您在提交转码作业时记录任务的JobID，便于后续进行查询、遍历等操作。

/**
 * 提交转码作业
 * @param client
 * @return
 * @throws Exception
 */
public static SubmitJobsResponse submitJobs(DefaultAcsClient client) throws Exception {

    SubmitJobsRequest request = new SubmitJobsRequest();
    //构建输出参数
    JSONArray outputs = new JSONArray();

    //构建input, 需要保证Location区域和服务client区域一致
    JSONObject input = new JSONObject();
    input.put("Location", "oss-cn-beijing");
    input.put("Bucket", "<your bucket name>");

    //构建一个输出对象
    JSONObject output = new JSONObject();
    try {
        input.put("Object", URLEncoder.encode("mps-test/demo/test.mp4", "utf-8"));
        String outPutObject = URLEncoder.encode("mps-test/demo/test-out.mp4", "utf-8");
        output.put("OutputObject", outPutObject);
    } catch (UnsupportedEncodingException e) {
        throw new RuntimeException("input URL encode failed");
    }
    output.put("TemplateId", templateId);
    outputs.add(output);

    request.setInput(input.toJSONString());
    request.setOutputs(outputs.toJSONString());
    //指定输出Bucket
    request.setOutputBucket("<your bucket name>");
    //输出Bucket的所在区域,格式: oss-cn-****, 例如北京oss-cn-beijing
    request.setOutputLocation("oss-cn-beijing");
    // PipelineId
    request.setPipelineId(pipelineId);

    return client.getAcsResponse(request);
}

查询转码作业

调用QueryJobList接口，完成查询转码作业功能。

/**
 * 查询转码作业
 * @param client
 * @return
 * @throws Exception
 */
public static QueryJobListResponse queryJobList(DefaultAcsClient client) throws Exception {

    QueryJobListRequest request = new QueryJobListRequest();
    //支持查询多个JobID,一次最多查询10个,使用半角逗号（,）分隔
    request.setJobIds("606179a72c64e572e****");

    return client.getAcsResponse(request);
}

取消转码作业

调用CancelJob接口，完成取消转码作业功能。

/**
 * 取消转码作业
 * @param client
 * @return
 * @throws Exception
 */
public static CancelJobResponse cancelJob(DefaultAcsClient client) throws Exception {

    CancelJobRequest request = new CancelJobRequest();
    request.setJobId("606179a72c64ee2b6****");

    return client.getAcsResponse(request);
}

遍历转码作业

调用ListJob接口，完成遍历转码作业功能。

/**
 * 遍历转码作业
 * @param client
 * @return
 * @throws Exception
 */
public static ListJobResponse listJob(DefaultAcsClient client) throws Exception {

    ListJobRequest request = new ListJobRequest();
    request.setState("All");

    return client.getAcsResponse(request);
}
