Querying Video Parsing Tasks

Notes

  • You can query video parsing tasks by task ID, task status, time range, or page number, or perform compound query.
  • If there are more than 10 records and the page number and maximum number of records on each page are not specified, 10 records are displayed by default on each page.

By Task ID

1
2
3
4
5
6
 
// You can query up to 10 tasks.
ListExtractTaskRequest req = new ListExtractTaskRequest().withTaskId(Collections.singletonList("3223182"));
// Send the request to MPC.
ListExtractTaskResponse rsp = initMpcClient().listExtractTask(req);
// Print the response message.
System.out.println("rsp=" + rsp.toString());

By Page Number

1
2
3
4
5
6
 
// Set the page number and number of records on each page.
ListExtractTaskRequest req = new ListExtractTaskRequest().withPage(0).withSize(10);
// Send the request to MPC.
ListExtractTaskResponse rsp = initMpcClient().listExtractTask(req);
// Print the response message.
System.out.println("rsp=" + rsp.toString());

By Time Range

1
2
3
4
5
6
 
// Set the start time and end time.
ListExtractTaskRequest req = new ListExtractTaskRequest().withStartTime("20201220131400").withEndTime("20201221131400");
// Send the request to MPC.
ListExtractTaskResponse rsp = initMpcClient().listExtractTask(req);
// Print the response message.
System.out.println("rsp=" + rsp.toString());

By Task Status

1
2
3
4
5
6
 
// Create a request for querying a task by task status.
ListExtractTaskRequest req = new ListExtractTaskRequest().withStatus(ListExtractTaskRequest.StatusEnum.FAILED);
// Send the request to MPC.
ListExtractTaskResponse rsp = initMpcClient().listExtractTask(req);
// Print the response message.
System.out.println("rsp=" + rsp.toString());

Compound Query

1
2
3
4
5
6
7
8
 
// Configure the following parameters:
ListExtractTaskRequest req = new ListExtractTaskRequest().withPage(0).withSize(10)
        .withStartTime("20201220131400").withEndTime("20201221131400")
        .withStatus(ListExtractTaskRequest.StatusEnum.FAILED);
// Send the request to MPC.
ListExtractTaskResponse rsp = initMpcClient().listExtractTask(req);
// Print the response message.
System.out.println("rsp=" + rsp.toString());
