Ping

ping (-d=DO) (-t=1) (-o=ping.json)

test ping using https://github.com/jakejarvis/provider-speed-tests:

-d --provider = to selected provider in list (DO, AWS, ALL)
-t --tries = number of ping tests
-o --output = output filename, default ping.json

example result json:

{"DO-NYC1": 134.531, "DO-NYC2": 132.959, "DO-NYC3": 133.545}

Bestping

bestping (ping1.json, ...) (-o=bestping.json)

calculate and return best ping provider from provided ping json files

-o --output = output filename, default bestping.json

example result:

{'region': 'fra1', 'provider': 'DO', 'host': 'speedtest-fra1.digitalocean.com', 'ping': 112.962}

Config

config direct/forwarder (-b=1000) (--mss=1360) (--payload=1316) (--latency=500) \
(--provider=DO) (--region=fra1) (--forwarder_rcv_port=1234) (--forwarder_snd_port=1235) (-o=config.json)

Create direct/forwarder srt config for sender, receiver, and optional forwarder

mode = direct/forwarder
-b --bitrate = bitrate of video, default 1000
--mss = mss, default 1360
--payload = payload, default 1316
--latency = latency, default 500

--provider = forwarder server provider to get instance, required if ip not set
--region = forwarder server provider to get instance, required if ip not set
--ip = forwarder server ip, required if provider not set
--user = forwarder server user, default=root

--rcv_ip = forwarder server receive ip, optional
--rcv_port = forwarder server receive port, default 1234
--snd_ip = forwarder server send ip, optional
--snd_port = forwarder server send port, default 1235
--name = forwarder server docker container name, default forwarder_{rcv}_{snd}

-o --output = output filename, default config.json

example result json:

{
    "sender": "srt://X.X.X.X:1234?transtype=live&rcvlatency=50&peerlatency=50&fc=104&rcvbuf=1006600&sndbuf=1006600&payloadsize=1316&mss=1360",

    "forwarder_ip": "X.X.X.X",
    "forwarder_rcv": "X.X.X.X:1234",
    "forwarder_snd": "X.X.X.X:1235",

example direct request

srthelper config direct -b 1000000 --rtt 300 --latency 1000 --ip=136.243.3.102 --src_ip=204.48.27.153

example srt config response
