How to extract audio from video in java

@micheal john • 10 Nov, 2014 https://www.javatpoint.com/q/5931/java-code-for-converting-audio-to-text-and-video-to-audio

@radha gogia • 10 Nov, 2014 I have imported the respective jar files but one audio clip is generated but it is of 0 bytes and i am getting this error.

[main] ERROR org.ffmpeg - [mp3 @ 04D5F8A0] Invalid audio stream. Exactly one MP3 audio stream is required.
[main] ERROR com.xuggle.xuggler - Error: could not write header for container (../../../../../../../csrc/com/xuggle/xuggler/Container.cpp:827)

I just tried this and, it works perfectly fine.
Make sure you give correct path of source file.

import it.sauronsoftware.jave.InputFormatException;

public class AviToMp3 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        File source = new File("source.avi");
        File target = new File("target.mp3");
        AudioAttributes audio = new AudioAttributes();
        audio.setCodec("libmp3lame");
        audio.setBitRate(new Integer(128000));
        audio.setChannels(new Integer(2));
        audio.setSamplingRate(new Integer(44100));
        EncodingAttributes attrs = new EncodingAttributes();
        attrs.setFormat("mp3");
        attrs.setAudioAttributes(audio);
        Encoder encoder = new Encoder();
        try {
            encoder.encode(source, target, attrs);
        } catch (IllegalArgumentException | EncoderException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}

getting the text from the mp3 file,

What kind of text you want to extract? Media Information?
It is there

public it.sauronsoftware.jave.MultimediaInfo getInfo(java.io.File source)
                                             throws it.sauronsoftware.jave.InputFormatException,

I want to extract the lyrics from the audio file and then make a text document of those lyrics.

@Anoop Kumar • 11 Nov, 2014 If it is part of metadata then you can extact it. Otherwise are you trying to get voice recognition

Yes ,it is a case of voice recognition only and I am trying to get the words,actually they will be extracted from a lecture audio,so firstly i have to remove noise signals and extract only the tracker voice ,also the format in which sphinx which actually works as a voice recongintion tool in java works is through microphone and i have to extract it through mp3 file so thats the major issue.

@Anoop Kumar • 11 Nov, 2014 • 1 like You are looking for Speech recognition system.
Are you looking for offline audio to text then I guess, it's very difficult to get desired result. You can only convert a speech (audio stream going into microphone).
You can see Java Speech API. If you are looking for streaming audio in mic to text. But still it's not very good, When even online and much sophisticated Google Now and Apple SIRI are struggling with this. If you are looking for speech to text then go for google translate or any online conversion method. See if Java Speech API works.
I see the Linkdin discussion, they are talking about converting mp3 int binary stream not in the text.

Actually ,if you saw the linkdin discussion,there one person Denis talked about that we can do convert it into text if the file is wav format,he even provided with a code,I have made my mp3 file into wav file,and even sphinx in java used for speech recognition also works through micropohne and usually the voice signal of a human is taken in wav format so now can i do something becoz my audio file is a mere english video lecture and i want to just make a text document of it,so now see if wav file is of any use,see even if text document is not made,now can you think of any other utility if in any way text is not possible because in there are merely words only spoken in a lecture,so I guess something can be done.

@Anoop Kumar • 12 Nov, 2014 Are you sure you ware sending Mp4 before?
Method suggest it is expecting Avi.
