We have released farm-ng-core v0.1.3 !!

See the changelog in the link below

This release goes accompanied by an update of the file_reader example in farm-ng-amiga, which introduces the EventsLogPosition API to easily implement fast events filtering with the EventsFileReader.

You can now get the index from the EventFileReader and perform filtering with Python list comprehension

farm-ng/farm-ng-amiga/blob/3916630a17322caaaeaca76627a919c349c046ce/py/examples/file_reader/main.py#L36-L42


      
          # filter the events containing `oak_pb2.OakDataSample`
          events: List[EventLogPosition] = [
              x for x in reader.get_index() if event_has_message(x.event, oak_pb2.OakDataSample)
          ]
          
          
# filter the image based events by camera name
          cam_events: List[EventLogPosition] = [x for x in events if x.event.uri.path == f"{camera_name}/video"]

Then you can easily parse the message directly from the event log

          for event_log in cam_events:
              # parse the message
              sample: oak_pb2.OakDataSample
              sample = event_log.read_message()
