NvSciEventService Initialization
NvSciStream can optionally use NvSciEventService for event notification.
For each NvSciStream block, applications can request an
NvSciEventNotifier object on which applications can wait for new events in
the block. Applications can also provide the NvSciEventService to handle
internal NvIpc events and I/O messages on the IpcSrc and
IpcDst blocks.
Refer to the NvSciEventService API Usage section on how to set up NvSciEventService and wait on an NvSciEventHandler object.
