本文提供了Node.js SDK拼接开板和尾板的操作步骤及完整的代码示例。
操作步骤
- 创建Client实例。
var RPCClient = require('@alicloud/pop-core').RPCClient; var client = initVodClient('<Your AccessKeyId>', '<Your AccessKeySecret>', '<YourRegionId>');
- 设置转码参数。
- Input
var input = {}; input.Location= ossLocation; input.Bucket= ossBucket; input.Object=encodeURIComponent(headObject);
- Output
var outputOSSObject=encodeURIComponent(ossOutputObject);; var output = {}; output.OutputObject= outputOSSObject; output.TemplateId= templateId;
- Video
var video = {}; video.Width= "1280"; video.Height= "720"); output.Video=JSON.stringify(video);
- OpeningList
var openingVideo = {}; var httpStri="http://"; var dot='.'; var openingVideoURL=httpStri.concat(ossBucket, dot,ossLocation, dot, 'aliyuncs.com/', encodeURIComponent(headObject)); openingVideo.OpenUrl= openingVideoURL; openingVideo.Width="640"; openingVideo.Start= "2"; var openingVideoList = new Array(); openingVideoList.push(openingVideo); output.OpeningList= JSON.stringify(openingVideoList);
- TailSlateList
var tailSlateVideo = {}; var httpStri="http://"; var dot='.'; var tailSlateVideoURL=httpStri.concat(ossBucket, dot, ossLocation, dot, 'aliyuncs.com/', encodeURIComponent(tailObject)); tailSlateVideo.TailUrl= tailSlateVideoURL; tailSlateVideo.Width= "640"; tailSlateVideo.BlendDuration= "3"; tailSlateVideo.BgColor= "Black"; var tailSlateVideoList = new Array(); tailSlateVideoList.push(tailSlateVideo); output.TailSlateList= JSON.stringify(tailSlateVideoList);
- Input
- 发起API请求并显示返回值。
var client=client.request('SubmitJobs', { Input: JSON.stringify(input), Outputs: JSON.stringtify(outputs), OutputBucket: ossBucket, PipelineId: pipelineId, OutputLocation: ossLocation }, {}).then(function (response) { console.log('response success: = ' + response.JobResultList.JobResult[0].Success); console.log('response jobID: ' + response.JobResultList.JobResult[0].Job.JobId); }).catch(function (response) { console.log(JSON.stringify(response)); });
var accessKeyId = "xxx";
var accessKeySecret = "xxx";
var mpsRegionId = "xxx";
var pipelineId = "xxx";
var templateId = "S00000001-200030";
var ossLocation = "xxx";
var ossBucket = "xxx";
var ossInputObject = "xxx.mp4";
var ossOutputObject = "xxx.mp4";
var headObject = "head.mp4";
var tailObject = "tail.mp4";
var httpStri = "http://";
var dot = '.';
var RPCClient = require('@alicloud/pop-core').RPCClient;
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 client = initMtsClient(accessKeyId, accessKeySecret, mpsRegionId);
var input = {};
input.Location = ossLocation;
input.Bucket = ossBucket;
input.Object = encodeURIComponent(ossInputObject);
var outputOSSObject = encodeURIComponent(ossOutputObject);
var output = {};
output.OutputObject = outputOSSObject;
output.TemplateId = templateId;
// Output->OpeningList
var openingVideo = {};
var openingVideoURL = httpStri.concat(ossBucket, dot, ossLocation, dot, 'aliyuncs.com/',
encodeURIComponent(headObject));
openingVideo.OpenUrl = openingVideoURL;
openingVideo.Width = "640";
openingVideo.Start = "2";
var openingVideoList = new Array();
openingVideoList.push(openingVideo);
output.OpeningList = JSON.stringify(openingVideoList);
// Output->TailSlateList
var tailSlateVideo = {};
var tailSlateVideoURL = httpStri.concat(ossBucket, dot, ossLocation, dot, 'aliyuncs.com/',
encodeURIComponent(tailObject));
tailSlateVideo.TailUrl = tailSlateVideoURL;
tailSlateVideo.Width = "640";
tailSlateVideo.BlendDuration = "3";
tailSlateVideo.BgColor = "Black";
var tailSlateVideoList = new Array();
tailSlateVideoList.push(tailSlateVideo);
output.TailSlateList = JSON.stringify(tailSlateVideoList);
// Outputs
var outputs = new Array();
outputs.push(output);
var client = client.request('SubmitJobs', {
Input: JSON.stringify(input),
Outputs: JSON.stringify(outputs),
OutputBucket: ossBucket,
PipelineId: pipelineId,
OutputLocation: ossLocation
}, {}).then(function (response) {
console.log('response success: = ' + response.JobResultList.JobResult[0].Success);
console.log('response jobID: ' + response.JobResultList.JobResult[0].Job.JobId);
console.log(JSON.stringify(response));
}).catch(function (response) {
console.log(JSON.stringify(response));
});
