The encoder uses a simple alternating reference frame strategy:

  • For P-frames, it uses the last reconstructed frame as a reference.
  • To simplify the reference model of the encoder, the encoder alternates between two reference frame slots (typically slot 0 and slot 1) for storing reconstructed images and providing prediction references for the next frame.
