Hi all,
I’ve used vlc to encode live stream and then send it to wowza server. However, i want to sent the output encoded to 2 wowza server. I’ve used duplicate module, but it still not work:
cvlc -vvv input stream – sout “#transcode{vcodec=x264,fps=25,vb=200,width=480,height=360,scale=1,acodec=mp3,ab=64,channels=2,samplerate=44100}:duplicate{dst=rtp{dst=x.x.x.x,port=20017,mux=ts},dst=rtp{dst=x.x.x.x,port=20018,mux=ts}}”
vlc error is:
