1. Define message formats in a .proto file.

   • Please refer to

     View file
     name frames.proto

     of Davinci Voice Engine.

2. Compile your .proto file to get the generated source code.

   • pre-compiled generated source code (ready-to-use)

     • Python

     • C

3. Include/import the generated source code with protocol buffer API to encode (serialize) and decode (deserialize) messages.

   • Example

     • Python

       程式碼區塊
       language py
       from protobuf import frames_pb2 from google.protobuf.json_format import MessageToJson # Encode (Serialize) fake_audio_data = b'\x00\x01\x02\x03' frame = frames_pb2.Frame() frame.audio.audio = fake_audio_data frame.audio.sample_rate = 16000 frame.audio.num_channels = 1 serialized_bystring = frame.SerializeToString() # Decode (deserialize) frame = frames_pb2.Frame() frame.ParseFromString(serialized_bystring) json_frame = MessageToJson(frame) ## Check the type of frame. if frame.HasField('audio'): pass elif frame.HasField('text'): pass

...

• Decoding:

  • Determine the frame type by inspecting the first byte, and the frame length by inspecting the following bytes. (Refer to the illustration below)

    • AudioRawFrame

      • The whole frame

        

    • TextFrame

      • The whole frame

...

• Encoding:

  • Must include the first few bytes indicating the frame type to the server.

    • AudioRawFrame

      • Bytestring starts from b'\x12'

    • TextFrame

      • Bytestring starts from b'\n'
