[FFmpeg-user] how ffmpeg use network streaming as input?

[zhangkai.gis]

Thanks for Michael's command line.let me explain my problem more detail.Sorry for that I do not make the problem clear(my poor english :(...). I will have hundres of cameras to monitor.all the monitor report it's video,audio and other information to  my server via tcp connection.I filter the video message and combine the messages together.Now I want to encode the stream to nginx+rtmp via ffmpeg.Maybe I can first save it to file.Then use ffmpeg to send it.But I want to seek other better way to handle the video stream. 
Hope I make my problem clear ;P
Thanks,
zhangkai
