This topic provides examples on how to use the API operations of the media fingerprinting module. The API operations are encapsulated in ApsaraVideo VOD SDK for Node.js. You can call the API operations to submit media fingerprinting jobs, query media fingerprinting jobs, and query media fingerprinting results.
Initialize a client
Before you can use the SDK, initialize a client. For more information, see Initialization.
Submit a media fingerprinting job
You can call the SubmitAIJob operation to submit a media fingerprinting job.
For more information about the request and response parameters of this operation, see SubmitAIJob. Example:
You can call the SubmitAIJob operation to submit a media fingerprinting job.
For more information about the request and response parameters of this operation, see SubmitAIJob. Example:
// Call example
var client = initVodClient('<Your AccessKeyId>','<Your AccessKeySecret>');
client.request("SubmitAIJob", {
MediaId: '584625a507a44d0eaa7424afd56****',
Types: 'AIMediaDNA'
}, {}).then(function (response) {
if (response.AIJobList && response.AIJobList.AIJob && response.AIJobList.AIJob.length > 0){
for(var i=0; i<response.AIJobList.AIJob.length; i++){
var job = response.AIJobList.AIJob[i];
// The video ID.
console.log('MediaId = ' + job.MediaId);
// The job ID.
console.log('JobId = ' + job.JobId);
// The AI type.
console.log('Type = ' + job.Type);
}
}
console.log('RequestId = ' + response.RequestId);
}).catch(function (response) {
console.log('ErrorCode = ' + response.data.Code);
console.log('ErrorMessage = ' + response.data.Message);
console.log('RequestId = ' + response.data.RequestId);
});
Query media fingerprinting jobs
You can call the ListAIJob operation to query media fingerprinting jobs.
For more information about the request and response parameters of this operation, see ListAIJob. Example:
You can call the ListAIJob operation to query media fingerprinting jobs.
For more information about the request and response parameters of this operation, see ListAIJob. Example:
// Call example
var client = initVodClient('<Your AccessKeyId>','<Your AccessKeySecret>');
client.request("ListAIJob", {
JobIds: 'JobId1,JobId2'
}, {}).then(function (response) {
// List details about jobs.
console.log("============ AIJobList ============");
if (response.AIJobList && response.AIJobList.AIJob && response.AIJobList.AIJob.length > 0){
for(var i=0; i<response.AIJobList.AIJob.length; i++){
var job = response.AIJobList.AIJob[i];
// The video ID.
console.log('MediaId = ' + job.MediaId);
// The job ID.
console.log('JobId = ' + job.JobId);
// The AI type. Set the value to AIMediaDNA.
console.log('Type = ' + job.Type);
// The job status.
console.log('Status = ' + job.Status);
// The job result.
console.log('Data = ' + job.Data);
}
}
// List the IDs of jobs that do not exist.
console.log("============ NonExistAIJobIds ============");
if (response.NonExistAIJobIds && response.NonExistAIJobIds.String && response.NonExistAIJobIds.String.length > 0) {
for (var i=0; i<response.NonExistAIJobIds.String.length; i++) {
// The job ID.
console.log('NonExistAIJobId = ' + response.NonExistAIJobIds.String[i]);
}
}
console.log('RequestId = ' + response.RequestId);
}).catch(function (response) {
console.log('ErrorCode = ' + response.data.Code);
console.log('ErrorMessage = ' + response.data.Message);
console.log('RequestId = ' + response.data.RequestId);
});
Query media fingerprinting results
You can call the GetMediaDNAResult operation to query media fingerprinting results.
For more information about the request and response parameters of this operation, see GetMediaDNAResult. Example:
You can call the GetMediaDNAResult operation to query media fingerprinting results.
For more information about the request and response parameters of this operation, see GetMediaDNAResult. Example:
// Call example
var client = initVodClient('<Your AccessKeyId>','<Your AccessKeySecret>');
client.request("GetMediaDNAResult", {
MediaId: '584625a507a44d0eaa7424afd56****'
}, {}).then(function (response) {
// List media fingerprinting results.
console.log("DNAResult = ");
console.log(response.DNAResult);
console.log('RequestId = ' + response.RequestId);
}).catch(function (response) {
console.log('ErrorCode = ' + response.data.Code);
console.log('ErrorMessage = ' + response.data.Message);
console.log('RequestId = ' + response.data.RequestId);
});
