I am working on a VLC project for myself. My goal is to create the front of the HTML to start the stream. I do this using Java Servlets.
Overview: Ubuntu 13.04, Java 7-21: IcedTea 2.3.9, Eclipse JAVAEE IDE, Tomcat 7
I am trying to start a VLC HTTP video stream using this call.
vlc -vvv /home/jca310ms/Videos/test.avi.flv \
--sout '#transcode{vcodec=FLV1,vb=4096,fps=25,scale=1,acodec=mp3,ab=512,samplerate=44100,channels=2}:std{access=http,mux=flv,dst=0.0.0.0:8081/stream.flv}'
Now this call works from the command line. However, when it starts using:
String args = "vlc -vvv /home/jca310ms/Videos/test.avi.flv --sout '#transcode{vcodec=FLV1,vb=4096,fps=25,scale=1,acodec=mp3,ab=512,samplerate=44100,channels=2}:std{access=http,mux=flv,dst=0.0.0.0:8081/stream.flv}'";
Runtime runtime = Runtime.getRuntime();
Process p = runtime.exec(args);
I get these errors from the output:
err: [0x7ff2d8000b78] main input debug: Creating an input for 'test.avi.flv'
err: [0x7ff2ac001108] main stream output debug: using sout chain=`standard{mux="",access="'#transcode{vcodec=FLV1,vb=4096,fps=25,scale=1,acodec=mp3,ab=512,samplerate=44100,channels=2}",dst="std{access=http,mux=flv,dst=0.0.0.0:8081/stream.flv }'"}'

Any ideas that might make a difference between the ability of vlc to start a stream through the console, but not be able to start the stream using runtime.exec ()?
Any help is appreciated !!!
