There are different understanding of forward references(could be past frames or future frames) and backward references (could be past frames or future frames).
This flag allows the user to configure the reference as past or future frames.
- Value 0: by default, forward_references mean future frames, backward_references mean past frames
- Value 1: swap, forward_references mean past frames, backward_references mean future frames
