Tuning for Latency
If streaming to the VLC media player, latency can be reduced on the decode side by adjusting the
network caching value. By default, this is set to 1000ms. You can lower this to as low as 200ms. To do
this, go to the following:
VLC

Tools
→
Preferences
→
Show Settings (ALL)
→
Input / Codecs
→
Network caching (ms)
For other methods on how to reduce latency, see Z3’s How to Achieve Low Latency Guide (DOC
