Talk:Madsonic

to play as jukebox on the server

first you need to change ffmpeg, it is too recent for our kernel !

1. /var/madsonic/transcode/ffmpeg -i ./01-*

FATAL: kernel too old
Erreur de segmentation

I have taken the ffmpeg from the package subsonic for sme it works well

 mv /var/madsonic/transcode/ffmpeg /var/madsonic/transcode/ffmpeg.old
 cp -a /var/subsonic/transcode/ffmpeg /var/madsonic/transcode/

 /var/madsonic/transcode/ffmpeg -i ./01-*

then find your audio device and configure

yum install java-1.7.0-openjdk-devel java-openjdk-devel -y

vim audioDevList.java

coder to paste

import java.io.*;
import javax.sound.sampled.*; 

public class audioDevList{
public static void main(String args[]){

//Get and display a list of
// available mixers.

Mixer.Info[] mixerInfo =
AudioSystem.getMixerInfo();
System.out.println("Available mixers:");
for(int cnt = 0; cnt < mixerInfo.length;
cnt++){
System.out.println(mixerInfo[cnt].
getName());
}//end for loop
}
} 

then

javac audioDevList.java
java audioDevList

should return something like

# java audioDevList
Available mixers:
dmix:0 [default]
Intel [plughw:0,0]
Intel [plughw:0,1]
Port Intel [hw:0]

Now edit sound.properties in Java installation used to run SubSonic and add:

javax.sound.sampled.Clip=#Intel [plughw:0,0] javax.sound.sampled.Port=#Port Intel [hw:0] javax.sound.sampled.SourceDataLine=#Intel [plughw:0,0] javax.sound.sampled.TargetDataLine=#Intel [plughw:0,0]

In my case, file was: /

vim /usr/lib/jvm/java-1.7.0/jre/lib/sound.properties
vim /usr/lib/jvm/java-1.6.0/jre/lib/sound.properties 

that works, but now ALL Java apps on my system output audio to that device - which defeats the purpose of having ONLY music played on that device, avoiding system sounds like incoming mail notifications blowing your ears out at 110 decibels....

alternatively :

vim /usr/bin/madsonic

Adding after -verbose:gc \ line

 '-Djavax.sound.sampled.SourceDataLine=#Intel [plughw:0,0]'\

should work ...
