I tried to use a example to create a stream.

Example:

ffmpeg -re -i febrstar.mp4 -c copy -f flv rtmp://192.168.0.100:8080/febrstar
or
ffmpeg -re -i febrstar.mp4 -acodec copy -vcodec copy -f flv rtmp://192.168.0.100:8080/febrstar

where
febrstar.mp4 - real file
192.168.0.100:8080 - my local host and port

But in all cases instead of the stream, I get an error message

[COLOR="rgb(139, 0, 0)"]RTMP_Connect0, failed to connect socket. 10051 (unknow error)
rtmp://192.168.0.100:8080/febrstar: unknow error occured[/COLOR]

Port 8080 is open.
When i create a stream with VLC, all work is normally and i see a stream on other computers.
But VLC not create stream in 'rtmp' format and i want to create a stream with ffmpeg.

I will be very grateful if you help me solve this problem.
