[Tiến Dũng Nguyễn]

Hi Mr,Mrs Support,

I have installed ffmpeg server with this guide:
https://trac.ffmpeg.org/wiki/CompilationGuide/Centos
and i received from "a source" (for instance live or UDP) and then
transcode and re-broadcast the stream.
I followed this guide : https://trac.ffmpeg.org/wiki/StreamingGuide
But when i use command :
ffmpeg -i 'udp://localhost:5000?fifo_size=1000000&overrun_nonfatal=1' -crf
30 -preset ultrafast -acodec aac -strict experimental -ar 44100 -ac 2 -b:a
96k -vcodec libx264 -r 25 -b:v 500k -f flv 'rtmp://<wowza server
IP>/live/cam0'
Nothing happend.( i alr complete my udp and wowza serverIP )
It's not work.
Pls kindly help me reslove it.
Many thanks!
