I realize vlc vod,now i think to realize vlc multicast,i do an follow:
[root@localhost vlc-0.8.6c]# ./vlc -vvv udp:@238.0.0.1
VLC media player 0.8.6c Janus
starting VLC root wrapper... using UID 0 (root)
***************************************
* Running VLC as root is discouraged. *
***************************************
It is potentially dangerous, and might not even work properly.
