Many users use web-service like SpeedTest.net for detect incoming/outgoing speed of Internet connection.
It's perfect but for live-streaming this measurement result can be not true, because:
It means such measurement can shows 50 Mbs but in really for live-streaming you will get 5 Mbs only.
We provide special speed-test feature for SRTMiniServer
Type server url and stream id to SRTStreamer and press "Speed test"
result of measurement
If you see big value for "lost pkts" (>10%) then increase "latency" field
For example you got 5000 Kbs. We recommend setup 80% for live streaming ( 4000Kbs).
