[Live-devel] About transfer of RTP / RTCP

[吉原正信]

live555 Dear Developer

I am promoting the development of stream transfer system
and I plan to use live 555.
I have some questions but please check one by one.

I am developing a relay system for stream data. Transfer 
RTP / RTCP packets from the IP camera connected via Ethernet
to the receiving system. Transmission system and reception system
are wireless communication and unidirectional communication. 
The software interface of wireless communication is a unique
interface (hardware access) without using socket. 
Only IP and port number need to be changed and transferred.

I confirmed the source of "testRTSPClient.cpp".
The DummySink class was able to acquire media data,
but there was no RTP header.
I think that it is probably because the source class
is automatically specified as an appropriate class.

Next I confirmed the source of "testRelay.cpp".
I do not use the BasicUDPSink class on my system,
but I think that you can create your own class derived
from the MediaSink class.
In that way, we think that we can change IP packet to only
the destination, destination IP and port number and transfer
it to the receiving system.

Is this idea correct?

Please answer and give advice.
