Thank you for the opportunity to ask a question and for your very quick 
response

Unexpectedly, it seems ffplay, VLC (for RTP), rtsp-simple-server do it 
simply.
So the scheme in the documentation is not correct 
http://live555.com/proxyServer/

[back-end RTSP/RTP stream] --> [LIVE555 Proxy Server]... BUT [back-end 
RTSP/RTP SERVER] --> [LIVE555 Proxy Server]...

Then it is easier to use forwarding in the firewall, it works much 
faster.

Did I understand you correctly that I will need to copy the buffer to 
memory (test.h264) in a single thread for your server to work and this 
will lead to a decrease in live stream fps on my highly loaded H3 SoC 
from Allwinner (about 75% CPU for transcoding) ?
