Querying Task
In addition to receiving notifications of file transcoding results through the event notification mechanism, MPS users can also query details of a specified transcoding task through the DescribeTaskDetail API. This API is generally used to query the progress and results of a transcoding task that was manually initiated by the ProcessMedia API. Returned results can be
WAITING, PROCESSING, or FINISH.WAITING: The task has been initiated and is waiting to be processed.
PROCESSING: The task is being processed.
FINISH: The task has been completed.
Below are some task status samples:
