/** A synchronous method for processing batch data or offline streaming data. This method is
designed for processing either batch data such as unrelated images and texts or offline streaming
data such as the decoded frames from a video file and an audio file. The call blocks the current
thread until a failure status or a successful result is returned. If the input packets have no
timestamp, an internal timestamp will be assigend per invocation. Otherwise, when the timestamp is
set in the input packets, the caller must ensure that the input packet timestamps are greater than
the timestamps of the previous invocation. This method is thread-unsafe and it is the caller's
responsibility to synchronize access to this method across multiple threads and to ensure that the
input packet timestamps are in order.*/
