http://localhost:1234: Input/output error
I get Input/output error.
in linux its working with ffserver.
but in windows I get this exception.

Answer 1

You are using two different protocols (udp and http) so the outcome of the command is different.
Like Ross said in the comments : "UDP doesn't know or care if there is anything to receive the packets. If there's nothing there ffmpeg won't know and so won't complain".
FFserver is a different command to FFmpeg hence the different outputs.
Linux will behave differently according to distribution. Windows will also behave differently.
It would be easier for us to answer the question if you added a question mark to your question with a phrase summarising what you want to know.
