Hi,
just read the rtmpdump synopsis or help.Start CMD then enter PathToRtmpdumpFolder (or just copy CMD.exe into your rmtpdump folder to prevent entering the path).
rtmpdump.exe --help.Now you get the full parameter list + description.Below the link minimum datas to get it work.
Code:
rtmpdump -v -r "rtmp://cp86438.live.edgefcs.net/live" -y "livestream6_171@40495" | "player" -
