if cannot seekable when living stream. the duration and the filesize value
is 0, the value is wrong.
so i think remove it is a right way, because there have no describe to the
duration and the filesize for use,
some media player will use the value to control play duration. yes! that's
a shit media player, but i think it can fix by publish tools.

is this correct (that is according to hds specs) ?

so i think it can use a flvflags to control is write the duration and
filesize, for example FLV_RTMP  FLV_HDS is that right?
