截图

操作步骤

1. 创建client实例。

   var RPCClient = require('@alicloud/pop-core').RPCClient;
   
   var client = initVodClient('<Your AccessKeyId>', '<Your AccessKeySecret>', '<YourRegionId>');

2. 设置截图参数。
   • Input（作业输入）

     var input={
       Location: ossLocation,
       Bucket:ossBucket,
       Object:encodeURIComponent(ossInputObject)
     }

   • SnapshotConfig（截图配置）

     var snapshotConfig = {};

   • OutputFile（输出文件）

     var output = {};
     output.Location=ossLocation;
     output.Bucket=ossBucket;
     output.Object=encodeURIComponent(ossOutputObject);
     snapshotConfig.OutputFile=JSON.stringify(output);

   • Time（开始时间）

     snapshotConfig.Time="2";

   • Interval/Num（截图间隔）

     snapshotConfig.Interval="2";
     snapshotConfig.Num= "3";

   • Width/Height（宽度、高度）

     snapshotConfig.Height="360";

3. 发起API请求并显示返回值。

   var reponse=client.request('submitSnapshotJob',{
     Input:Json.stringify(input),
     SnapshotConfig:Json.stringify(snapshotConfig)});
   response = client.request()
   console.log("RequestId is:"+response.RequestId);
   console.log("JobId is:" + response.SnapshotJob.Id);
   console.log( "http://"+ossBucket+"."+ ossLocation+".aliyuncs.com/output_00001.jpg");
   console.log( "http://"+ossBucket+"."+ ossLocation+".aliyuncs.com/output_00002.jpg");
   console.log( "http://"+ossBucket+"."+ ossLocation+".aliyuncs.com/output_00003.jpg");

var accessKeyId = "xxx";
var accessKeySecret = "xxx";
var RegionId = "xxx";
var pipelineId = "xxx";
var ossLocation = "xxx";
var ossBucket = "xxx";
var ossInputObject = "input.mp4";//按需配置
var ossOutputObject = "output_{Count}.jpg";//按需配置

function initMtsClient(accessKeyId, accessKeySecret, regionId) {
    var client = new RPCClient({
        accessKeyId: accessKeyId,
        accessKeySecret: accessKeySecret,
        endpoint: 'http://mts.' + regionId + '.aliyuncs.com',
        apiVersion: '2014-06-18'
    });

    return client;
}

var RPCClient = require('@alicloud/pop-core').RPCClient;
var client = initMtsClient(accessKeyId, accessKeySecret, RegionId);
var input = {
    Location: ossLocation,
    Bucket: ossBucket,
    Object: encodeURIComponent(ossInputObject)
};

var snapshotConfig = {};
var output = {};
output.Location = ossLocation;
output.Bucket = ossBucket;
output.Object = encodeURIComponent(ossOutputObject);
snapshotConfig.OutputFile = JSON.stringify(output);
snapshotConfig.Time = "2";
snapshotConfig.Interval = "2";
snapshotConfig.Num = "3";
snapshotConfig.Height = "360";

client.request('submitSnapshotJob', {
    Input: JSON.stringify(input),
    SnapshotConfig: JSON.stringify(snapshotConfig),
    PipelineId: pipelineId
}).then(function (response) {
    console.log("RequestId is:" + response.RequestId);
    console.log("JobId is:" + response.SnapshotJob.Id);
    console.log("http://" + ossBucket + "." + ossLocation + ".aliyuncs.com/output_00001.jpg");
    console.log("http://" + ossBucket + "." + ossLocation + ".aliyuncs.com/output_00002.jpg");
    console.log("http://" + ossBucket + "." + ossLocation + ".aliyuncs.com/output_00003.jpg");
}).catch(function (response) {
    console.log(JSON.stringify(response));
});
