[Live-devel] Problem with RTSP streaming of HD Camera with Live555Proxyserver

[Ross Finlayson]

> 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.


> I start my software that use live555ProxyServer  and run code "live555ProxyServer -V -p 9002 -R rtsp://admin:369000@192.168.100.20:554/cam/realmonitor?channel=1&subtype=0"

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

> If I use only one RTSP client all it's fine: the video HD streaming result fine and not corrupt but, as soon as, i start another RTSP client (es. vlc) the video HD streaming result corrupt as in attached picture, WHY?

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.)
