> How can reduce NAL unit without change resolution and FPS

Ask the manufacturer of your encoder to upgrade it so that it can break up 
I-frames into multiple 'slice' NAL units.

The "LIVE555 Proxy Server" has no "-p" option.

Is your first client VLC also, or only your second client?

If you're using VLC as a client, then be aware that - if your NAL units are 
excessively large - the first few received frames *will* be truncated.  VLC 
notices this and increases its buffer size, so after a few seconds should have 
increased its buffer size large enough.  (However, VLC is not our software, so 
we can't help you with VLC-related problems.)
