Thanks for your help. I added a class similar to
MPEG2TransportFileServerMediaSubsession and another
class similar to MPEG2TransportStreamFramer, and just
modified the createNewRTPSink function.
and also modified the createNewStreamSource function
to the new streamframer class,
in that class, 
I simply removed the transport stream related code,
such as the sync byte and duration estimate part,
it seems that the client--openRTSP works good on PC
(Windows), but can't work on Embedded linux, there are
a lot of packets are lost.

can you give me some help for this problem?
Thanks a lot.
