Create a new GAP event. A gap event can be thought of as conceptually
equivalent to a buffer to signal that there is no data for a certain
amount of time. This is useful to signal a gap to downstream elements
which may wait for data, such as muxers or mixers or overlays, especially
for sparse streams such as subtitle streams.
