This article mainly introduces how to use Java to achieve video to audio batch conversion, the article is very detailed, has a certain reference value, interested friends must read it!

The implementation of this function requires the use of a third-party jar package jave,JAVE is an encapsulation tool for java to call FFmpeg.

Add the following dependencies to the spring boot project pom file

Ws.schild jave-core 3.1.1 ws.schild jave-nativebin-win64 3.1.1 Ws.schild jave-nativebin-linux64 3.1.1

Java single-class implementation code, copied to the Spring boot project, using the idea editor main method to run.

Import ws.schild.jave.Encoder;import ws.schild.jave.EncoderException;import ws.schild.jave.MultimediaObject;import ws.schild.jave.encode.AudioAttributes;import ws.schild.jave.encode.EncodingAttributes; import java.io.File;import java.util.Arrays; public class VideoToAudio {/ / Audio format private static String outputFormat= "mp3" to be output / * obtain the converted file name * @ param sourceFilePath: source video file path * @ return * / public static String getNewFileName (String sourceFilePath) {File source = new File (sourceFilePath); String fileName=source.getName () .substring (0, source.getName () .lastIndexOf (".")); return fileName+ "." + outputFormat } / * convert audio format * @ param sourceFilePath: source video file path * @ param targetFilePath: destination music file path * @ return * / public static void transform (String sourceFilePath, String targetFilePath) {File source = new File (sourceFilePath); File target = new File (targetFilePath); / / set audio attribute AudioAttributes audio = new AudioAttributes () Audio.setCodec (null); / / set transcoding properties EncodingAttributes attrs = new EncodingAttributes (); attrs.setOutputFormat (outputFormat); attrs.setAudioAttributes (audio); try {/ / Audio conversion format class Encoder encoder = new Encoder (); MultimediaObject mediaObject=new MultimediaObject (source); encoder.encode (mediaObject, target, attrs) System.out.println ("conversion completed...");} catch (EncoderException e) {e.printStackTrace () }} / * batch convert audio format * @ param sourceFolderPath: source video folder path * @ param targetFolderPath: destination music folder path * @ return * / public static void batchTransform (String sourceFolderPath, String targetFolderPath) {File sourceFolder = new File (sourceFolderPath) If (sourceFolder.list () .forEach (e-> {transform (sourceFolderPath+ "\" + e, targetFolderPath+ "\" + getNewFileName (e));}} public static void main (String [] args) {batchTransform ("C:\ Users\ tarzan\ Desktop\ video", "C:\ Users\ tarzan\ Desktop\ audio") }} above are all the contents of the article "how to use Java to convert video to audio in batch".
