OK understood. Thanks for the information.

Actually I thought it would be using TCP in any case, good to know UDP is the 
default. So it like using ffmpeg "-rtsp_transport tcp" parameter on the client 
side then.

That’s for RTSP/RTP-over-HTTP, which our server supports, but which you 
probably don’t need, unless you have a firewall - between your server and 
client - that blocks all ports except port 80.

Otherwise, if your client can reach the server via the normal RTSP ports (554 
or 8554), then you just use RTSP as usual.  By default, this will give you 
RTP-over-UDP.  But if your have a firewall that blocks UDP packets, your client 
can, instead, request RTP-over-TCP (using the RTSP TCP connection).  You can 
test this using VLC (which automatically tries RTP-over-TCP within a few 
seconds if RTP-over-UDP doesn't work).  Or you can use our “openRTSP” 
command-line RTSP client, using the “-t” option.
