Querying Packaging Tasks

Notes

  • You can query packaging 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

// Query transcoding tasks.
QueryRemuxTaskRequest queryRemuxTaskRequest = new QueryRemuxTaskRequest();
LinkedList<String> taskIds = new LinkedList<>();
taskIds.add("2288");

queryRemuxTaskRequest.setTaskId(taskIds.toArray(new String[0]));

// Send a request to MPC.
QueryRemuxTaskResponse queryResponse = mpcClient.queryRemuxTask(queryRemuxTaskRequest);
// Return a message.
System.out.println("query: " + gson.toJson(queryResponse)  + "\n");

Query by Page Number

// Set the page number and number of records on each page.

QueryRemuxTaskRequest queryRemuxTaskRequest = new QueryRemuxTaskRequest();
queryRemuxTaskRequest.setPage(1);
queryRemuxTaskRequest.setSize(10);

// Send a request to MPC.
QueryRemuxTaskResponse queryResponse = mpcClient.queryRemuxTask(queryRemuxTaskRequest);
// Return a message.
System.out.println("query: " + gson.toJson(queryResponse)  + "\n");

Query by Time Range

queryRemuxTaskRequest.setEndTime("20180520141300");

// Send a request to MPC.
QueryRemuxTaskResponse queryResponse = mpcClient.queryRemuxTask(queryRemuxTaskRequest);
// Return a message.
System.out.println("query: " + gson.toJson(queryResponse)  + "\n");

Query by Task Status

QueryRemuxTaskRequest queryRemuxTaskRequest = new QueryRemuxTaskRequest();
queryRemuxTaskRequest.setStatus(CommonTask.STATUS_SUCCEED);
// Send a request to MPC.
QueryRemuxTaskResponse queryResponse = mpcClient.queryRemuxTask(queryRemuxTaskRequest);
// Return a message.

queryRemuxTaskRequest.setStartTime("20180520131400");
queryRemuxTaskRequest.setEndTime("20180520141300");
queryRemuxTaskRequest.setPage(1);

// Send a request to MPC.
QueryRemuxTaskResponse queryResponse = mpcClient.queryRemuxTask(queryRemuxTaskRequest);
