it could also be that the php can not find the command "cvlc". when you are on a command line there are environmental variables that define where to look for commands from the command line type "which cvlc" this should return a full path to the command. something like "/user/bin/something/cvlc" then in your script replace the command with the full path. exec("/user/bin/something/cvlc dvb:// :dvb-adapter=1 :no-video --sout '#standard{access=http,mux=asf,dst=10.10.1.53:8181}'"); On Tue, Feb 14, 2012 at 2:50 PM, Raymond Norton <admin at lctn.org> wrote: > Should have thought of that.
