新建转码任务
您可以通过创建转码MpcClient实例并设置相关参数新建转码任务。
核心代码
- 创建转码MpcClient实例。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
public static MpcClient initMpcClient() { //设置httpConfig HttpConfig httpConfig = HttpConfig.getDefaultHttpConfig().withIgnoreSSLVerification(true).withTimeout(3); //根据实际需要,是否设置http代理 //httpConfig.withProxyHost("xxxxxx").withProxyPort(xxxxxx).withProxyUsername("xxxxxx"). //withProxyPassword("xxxxxx"); //根据实际填写ak,sk,在控制台账号名下“我的凭证 > 访问密钥”上创建和查看您的AK/SK String ak = System.getenv("SDK_AK"); String sk = System.getenv("SDK_SK"); //根据实际填写项目ID,在控制台账号名下“我的凭证 > API凭证”下查看您的项目ID String projectId = System.getenv("PROJECT_ID"); //根据实际填写所需Endpoint,这里以“region01”为例 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(); }
- 创建转码请求,并设置请求体。
转码请求包括输入文件、输出文件和转码模板设置。具体参数含义请参考新建转码任务。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
//设置转码输入视频地址 ObsObjInfo input = new ObsObjInfo() //设置桶名 .withBucket("mpc-east-2") //设置OBS桶所在区域 .withLocation("region01") //设置输入视频对象 .withObject("input/ok.mp4"); //设置转码输出视频路径 ObsObjInfo output = new ObsObjInfo().withBucket("mpc-east-2").withLocation("region01") //设置输出路径 .withObject("output"); //创建转码请求 CreateTranscodingTaskRequest request = new CreateTranscodingTaskRequest().withBody(new CreateTranscodingReq() .withInput(input) .withOutput(output) //设置转码模板,预置模板Id可以在MPC console页面“全局设置 > 预置模板”上查看 .withTransTemplateId(Collections.singletonList(7000530)) //设置输出名称,名称个数需要与模板个数一一对应 .withOutputFilenames(Collections.singletonList("output_")) //设置截图参数,根据实际需要填充Thumbnail结构 //.withThumbnail(new Thumbnail()) //设置加密参数,根据实际需要填充Encryption结构 //.withEncryption(new Encryption()) );
- 发送转码请求。
1 2 3 4
//发送媒体处理服务请求 CreateTranscodingTaskResponse response = initMpcClient().createTranscodingTask(request); //返回消息 System.out.println("CreateTranscodingTaskResponse=" + response);
