[M4IF Technotes] Packet loss RDO in H.264

[#WEI JUN#]

Hi,
I tested packet loss RDO algorithm using default configure file
(RDOptimization=2, the packet loss rate are 10% for (first/second/third) partitions, 30 decoders, 1reference frame, source file: foreman.qcif)
 Frame   Bit/pic   QP   SnrY    SnrU    SnrV    Time(ms) Frm/Fld IntraMBs
  0(I)     23576   28 36.8903 39.6882 41.9991   2774       FRM

  4(P)     21160   28 35.5358 38.7110 40.9047  13850       FRM    88

Clearly, both the encoding time and generated bits increase. I wonder is it the best way to deal with packet loss? What's the benefit can we get from packet-loss RDO? Thanks
