Hi, I'm pretty new in developing programs in Java. I'm currently writing a program that converts a flv video into mp3. I have already written such a program in Visual Studio.net C#, but the Problem is, that it isn't cross platform compatible... I used the ffmpeg binary to convert the video into mp3, but I can't find ffmpeg binaries for Mac and Linux. (if so, I could start the specific binaries from java, depending on the OS) So I tried to convert the video with Xuggle, but the final mp3 has 0 bytes. My current code is the following:

IMediaReader reader = ToolFactory.makeReader("video.flv");
reader.addListener(ToolFactory.makeWriter("music.mp3", reader));
while (reader.readPacket() == null)
         do {} while(false);

Thanks in advance.

p.s sorry for my bad english
