腾讯云点播部署

腾讯云点播的部署

一、Maven 依赖引入

1、在项目的 pom.xml 文件添加点播 SDK 依赖即可

<dependency> 

  <groupId>com.qcloud</groupId>

  <artifactId>vod_api</artifactId>

  <version>2.1.4</version>

</dependency>

二、前端准备工作

（1）ajax发送点播请求，如图2所示：

注意：视频路径需是本地路径！

三、服务器端上传实现

（1）使用云 API 密钥初始化 VodUploadClient 实例。

注意：secretId、secretKey请在腾讯云账户信息里获取

VodUploadClient client = new VodUploadClient(secretId, secretKey);

（2）构造上传请求对象

1 2	VodUploadRequest request = new VodUploadRequest(); request.setMediaFilePath("/data/videos/Wildlife.wmv"); //参数为视频路径

（3）调用上传

调用上传方法，传入接入点地域及上传请求。

注意：接入点地域需前往云点播控制台查看

alt

可选取已开启的作为接入地域，下图代码填写的是重庆的接入点地域

client.upload（”ap-chongqing”）;

try {
        VodUploadResponse response = client.upload("ap-chongqing", request);
        logger.info("Upload FileId = {}", response.getFileId());
} catch (Exception e) {
        // 业务方进行异常处理
        logger.error("Upload Err", e);
}

（4）自适应码流设置

注意：自适应码流不设置将直接影响播放

** 图4：自适应码流视频处理接口调用**

 //视频自适应码流
 try{
        //秘钥信息对象
        Credential cred = new Credential(SecretId, SecretKey);
        //接口域名对象
        HttpProfile httpProfile = new HttpProfile();
        httpProfile.setEndpoint("vod.tencentcloudapi.com");
 
        ClientProfile clientProfile = new ClientProfile();
        clientProfile.setHttpProfile(httpProfile);
 
        VodClient vodClient = new VodClient(cred, "", clientProfile);
        //视频处理请求对象
        ProcessMediaRequest req = new ProcessMediaRequest();
        //设置自适应码流模板id
        MediaProcessTaskInput mediaProcessTaskInput1 = new MediaProcessTaskInput();
 
        AdaptiveDynamicStreamingTaskInput[] adaptiveDynamicStreamingTaskInputs1 = new AdaptiveDynamicStreamingTaskInput[2];
        AdaptiveDynamicStreamingTaskInputadaptiveDynamicStreamingTaskInput1 = new AdaptiveDynamicStreamingTaskInput();
                adaptiveDynamicStreamingTaskInput1.setDefinition(12L);
                adaptiveDynamicStreamingTaskInputs1[0] = adaptiveDynamicStreamingTaskInput1;
 
                AdaptiveDynamicStreamingTaskInput adaptiveDynamicStreamingTaskInput2 = new AdaptiveDynamicStreamingTaskInput();
                adaptiveDynamicStreamingTaskInput2.setDefinition(10L);
                adaptiveDynamicStreamingTaskInputs1[1] = adaptiveDynamicStreamingTaskInput2;
 
                mediaProcessTaskInput1.setAdaptiveDynamicStreamingTaskSet(adaptiveDynamicStreamingTaskInputs1);
 
        req.setMediaProcessTask(mediaProcessTaskInput1);
        //设置文件id
        req.setFileId(response.getFileId());
        //响应设置好的自适应模板id
        ProcessMediaResponse resp = vodClient.ProcessMedia(req);
 
        System.out.println(ProcessMediaResponse.toJsonString(resp));
} catch (TencentCloudSDKException e) {
         System.out.println(e.toString());
}
