What you describe looks like the delay introduced for interleaving: after a
subtitle packet at t=42 and video packets at t=42.1, 42.2, 42.3, the muxer
needs to wait for the next subtitle packet to check if per chance it would
not happen to be at t=42.1 too, because packets must be in ascending order
even in different streams.

Have a look at the max_interleave_delta option that was introduced recently.
