Querying Video Parsing Tasks

Notes

  • You can query video parsing tasks by task ID, task status, time range, page number, or compound query.
  • In the query results, if the page number and maximum number of displayed records are not specified, but the number of records is greater than 10, 10 records are displayed by default on each page.

Query by Task ID

// A maximum of 10 task IDs are supported.
QueryExtractTaskReq queryExtractReq = new QueryExtractTaskReq();
LinkedList<String> taskIds = new LinkedList<>();
taskIds.add("2288");
queryExtractReq.setTaskId(taskIds);

// Send a request to MPC.
QueryExtractTaskRsp queryResponse = mpcClient.queryExtractTask(queryExtractReq);
// Return a message.
System.out.println(new Gson().toJson(queryResponse));

Query by Page Number

// Set the page number and number of records on each page.
QueryExtractTaskReq queryExtractReq = new QueryExtractTaskReq();
queryExtractReq.setPage(1);
queryExtractReq.setSize(10);
// Send a request to MPC.
QueryExtractTaskRsp queryResponse = mpcClient.queryExtractTask(queryExtractReq);
// Return a message.
System.out.println(new Gson().toJson(queryResponse));

Query by Time Range

QueryExtractTaskReq queryExtractReq = new QueryExtractTaskReq();
queryExtractReq.setStartTime("20180520131400");
queryExtractReq.setEndTime("20180520141300");

// Send a request to MPC.
QueryExtractTaskRsp queryResponse = mpcClient.queryExtractTask(queryExtractReq);
// Return a message.
System.out.println(new Gson().toJson(queryResponse));

Query by Task Status

// Set the task status.
QueryExtractTaskReq queryExtractReq = new QueryExtractTaskReq();
queryExtractReq.setStatus(CommonTask.STATUS_SUCCEED);
// Send a request to MPC.
QueryExtractTaskRsp queryResponse = mpcClient.queryExtractTask(queryExtractReq);
// Return a message.
System.out.println(new Gson().toJson(queryResponse));

Compound Query

queryExtractReq.setEndTime("20180520141300");
queryExtractReq.setPage(1);
queryExtractReq.setSize(10);
queryExtractReq.setTaskId(taskIds);
queryExtractReq.setStatus(CommonTask.STATUS_SUCCEED);
// Send a request to MPC.
QueryExtractTaskRsp queryResponse = mpcClient.queryExtractTask(queryExtractReq);
// Return a message.
System.out.println(new Gson().toJson(rsp));
