I got the stream link like this:
rtmp://66.160.142.198/live/vtv31
I run rtmpdump command like this:
rtmpdump.exe -v -r "rtmp://66.160.142.198/live/vtv31" -o - | "C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" -

It says
Handshake: clien signature does not match!
info: Connected...
Error: rtmp send error
Error: rtmp server requested close

I try different stream link is ok such as:
rtmpdump.exe -v -r "rtmp://112.197.2.11:1935/live/sctv9.stream" -o - | "C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" -
