Querying Transcoding Tasks

You can query details about one or more transcoding tasks by task ID, task status, page number, start time, and end time.

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.

For details about the search criteria and search result parameters, see the API for querying transcoding tasks.
