(Sorry for the mistakes, but I am using the translation tool
Google).

I'm using Ubuntu. The command ". / Rtmpsuck" after redirection
firewall to port 1935, gives the following message when the video
appears:
"ERROR: RTMP_Connect1, handshake failed"
and
"ERROR: RTMP_ReadPacket, failed to read RTMP packet header."

How do I solve this problem?

Thank you for your attention

Try to use rtmpsrv instead.

Unless you post a link to the web-page you have problems with, nobody will be able to help you.
