So the player may fail to show the last frame before the large gap if
it doesn't have a good decoder. However with the current dts
calculation a player will fail to show the first X frames after the
gap if it seeks into the gap, even if the player would have a good
decoder.
(X depends on decode_delay and number of depending frames.)

The current system also requires unlimited buffering on the muxer side
when muxing live content: if one "live" stream has a gap, muxing has
to stop and all other streams must be buffered until the first frame
after the gap is available.
