The stream caching feature within VLC media
player is there to allow enough time for the data
being received to be converted to a stable or
smooth video feed.
The default caching value is 1500ms (milliseconds)
or 1.5 seconds. This delay behind the live
performance may be unacceptable but this value
can be changed and the delay reduced.
If sending the stream over an office network or
LAN,
this caching value can be reduced to around
50ms. If the video in the multi view is unstable then
slowly increase this caching value in 50 or 100ms
step until you have a smooth video feed.
Note: The VLC caching value and multi view stream size are also related to latency. Reducing the SE-1200
MU streamer size may also help reduce the multi view delay or latency across the IP network. The quality
of the multi view image will also be affected by these settings.
The VLC media player window (with SE-1200 MU multi view) can be displayed on a second computer
monitor using the Windows extended desktop feature. The main computer screen can then be used for
the SE-1200 MU control panel software.

5.2.3 Port Forwarding (Windows/MAC Users)
So that the SE-1200 MU Multi view stream can be seen and for the unit to be controlled beyond the
default gateway, certain ‘ports’ should be opened on your network firewall or gateway device.
TCP port 5000 is used for the VLC based multi view stream. Ports 5003 and 5004 are used for controlling
the switcher. These three ports should be forwarded to the SE-1200 MU internal private IP address.
