Configures whether the decoder requires a sync point before it starts
outputting data in the beginning. If enabled, the base class will discard
all non-sync point frames in the beginning and after a flush and does not
pass it to the subclass.
If the first frame is not a sync point, the base class will request a sync
point via the force-key-unit event.
