add setScaleMode callback
add HLS Initialized on boot
fix macroblock issues with certain streams
tags are sorted by DTS in HLSNetStream.as.
on the faulty streams we could see that several consecutive PES packets have same DTS but different PTS.
ex:
pts/dts:-29138409/-29138476
pts/dts:-29138442/-29138476
this case (same DTS, different PTS) was not handled properly in the sorting function.
while rethinking about it, this sort by DTS should now be useless as all tags should already be sorted in DTS order in TS, also AVCC and ADIF header are inserted at the right location.
solution is to remove this sorting. this should also save some CPU cycles.
