java实现的音视频格式转化器

一、前言
最近写了一款图形界面版的音视频格式转化器，可以实现将多种视频之间进行转化，非常好用，如将AVI转换为，TS，FLV，MP4等。音频可将MP3转成WAV。

二、实现
1.需引入相关maven依赖。

<!-- 核心包 --><dependency><groupId>ws.schild</groupId><artifactId>jave-core</artifactId><version>3.4.0</version></dependency><!-- Windows64位 --><dependency><groupId>ws.schild</groupId><artifactId>jave-nativebin-win64</artifactId><version>3.4.0</version></dependency>

2.编写相关音视频格式转换代码，如下：

 public static ConvertResult audioToAudioConverter(File source, File target, String audioCodec,String outFormat) {ConvertResult result = new ConvertResult();try {result.setSuccess(true);//设置音频流的编码属性AudioAttributes audio = new AudioAttributes();//libmp3lame表示使用LAME MP3编码器。LAME是一个开源的MP3编码器，FFmpeg中的libmp3lame就是LAME的实现。if (Objects.nonNull(audioCodec) && !audioCodec.equals("")) {audio.setCodec(audioCodec);}if (Objects.isNull(audioCodec) || Objects.equals(audioCodec,"libmp3lame")) {//在MP3编码中，通常的比特率范围是64 kbps到320 kbps。推荐的范围是128 kbps到256 kbps。较低的比特率会导致音频质量下降，但文件大小更小。audio.setBitRate(128000);//1单声道，2立体声audio.setChannels(2);//设置音频的采样率为44100Hz。这是CD质量的音频的标准采样率。audio.setSamplingRate(44100);}else {if (Objects.equals(audioCodec,"libmp3lame")) {//设置音频的采样率为44100Hz。这是CD质量的音频的标准采样率。audio.setSamplingRate(44100);//8BITS,16BTIS,24BTIS,32BTISaudio.setBitRate(1411100); //对于16bitaudio.setChannels(2);}}EncodingAttributes attrs = new EncodingAttributes();if (Objects.nonNull(outFormat) && !outFormat.equals("")) {attrs.setOutputFormat(outFormat);}attrs.setAudioAttributes(audio);Encoder encoder = new Encoder();MultimediaObject multimediaObject = new MultimediaObject(source);encoder.encode(multimediaObject, target, attrs);}catch (Exception e) {result.setSuccess(false);result.setMessage(e.getMessage());System.err.println(e);}return result;}public static ConvertResult converterToWav(File source,File target) {//wav编码格式 pcm_s16le 指定输出音频编码为PCM 16位小端序，指定输出音频编码为PCM 16位大端序，s表示signed u表示unsignedreturn audioToAudioConverter(source,target,"pcm_s16le","wav");}.............................

3.编写图形界面。

public class AudioVideoConverter {private List<String> errorMsgList = new ArrayList<>();static JLabel videoConvertJl,audioConvertJl,videoText,audioText;static JPanel videoJPanel,audioJPanel;boolean videoFlag = true;boolean audioFlag = false;static {videoConvertJl = new JLabel(new ImageIcon(AudioVideoConverter.class.getResource("/image/videoConvert.png")));audioConvertJl = new JLabel(new ImageIcon(AudioVideoConverter.class.getResource("/image/videoConvert.png")));videoText = new JLabel("视频转换");audioText = new JLabel("音频转换");videoJPanel = new JPanel();audioJPanel = new JPanel();videoJPanel.setBounds(50,4,62,62);videoJPanel.setBackground(new Color(55,50,50));videoConvertJl.setBounds(50, 3, 60, 60);videoJPanel.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));videoJPanel.add(videoConvertJl);videoText.setBounds(60, 71, 60, 15);audioConvertJl.setBounds(160, 4, 60, 60);audioJPanel.setBounds(160, 3, 62, 62);audioJPanel.setBackground(null);audioJPanel.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));audioJPanel.add(audioConvertJl);audioText.setBounds(170, 71, 80, 15);}...............................public static void main( String[] args ){	JFrame frame=new JFrame();AudioVideoConverter converter=new AudioVideoConverter();//视频转换与音频转换切换JLabel jl=new JLabel("选择转换到的格式：");String[] items = {"MP4", "MKV", "AVI", "WMV","TS","FLV","3GP"};final JComboBox<String> comboBox = new JComboBox<>(items);comboBox.setEditable(false);comboBox.setBounds(170, 105, 60, 20);final JComboBox<String> audioComboBox = converter.setAudioComboBox();JButton b=new JButton("选择文件");b.setHorizontalTextPosition(JButton.CENTER);//b.setBackground(new Color(195,17,17));b.setBorder(BorderFactory.createRaisedSoftBevelBorder());//去掉按钮文字周围的焦点框b.setFocusPainted(false);b.setBounds(240, 105, 80, 20);b.setVisible(true);jl.setBounds(50, 100, 150, 30);JTextArea area=new JTextArea(8,10);area.setBounds(50, 140, 550, 170);area.setBorder(BorderFactory.createLoweredSoftBevelBorder());area.setLineWrap(true);area.setVisible(true);area.setText("原视频地址\n");area.setEditable(false);JLabel jlPosition=new JLabel("保存位置：");jlPosition.setFont(new Font("宋体",Font.BOLD,14));jlPosition.setBounds(50, 320, 100, 30);ButtonGroup group = new ButtonGroup();JRadioButton option1 = new JRadioButton("保存在原视频相同位置");JRadioButton option2 = new JRadioButton("指定位置");group.add(option1);group.add(option2);// 默认选中第一个选项option1.setSelected(true);option1.setBackground(null);option2.setBackground(null);option1.setBounds(50, 360, 200, 20);option2.setBounds(50, 390, 80, 20);JTextField jt = new JTextField("");jt.setBounds(130, 390, 370, 20);JButton selectButton=new JButton("选择文件夹");selectButton.setHorizontalTextPosition(JButton.CENTER);selectButton.setBorder(BorderFactory.createRaisedSoftBevelBorder());//去掉按钮文字周围的焦点框selectButton.setFocusPainted(false);selectButton.setBounds(520, 390, 80, 20);selectButton.setVisible(true);selectButton.setEnabled(false);//开始转换JButton exchangeBt=new JButton("开始转换");exchangeBt.setHorizontalTextPosition(JButton.CENTER);exchangeBt.setBorder(BorderFactory.createRaisedSoftBevelBorder());//去掉按钮文字周围的焦点框exchangeBt.setFocusPainted(false);exchangeBt.setBounds(260, 470, 80, 20);exchangeBt.setVisible(true);frame.setSize(680, 600);frame.setTitle("音视频转换");frame.setLocationRelativeTo(null);// 创建一个ImageIcon对象ImageIcon icon = new ImageIcon(AudioVideoConverter.class.getResource("/image/videoAudioIcon.png"));// 调整图标大小Image image = icon.getImage(); // 获取原始图像Image newImage = image.getScaledInstance(16, 16, Image.SCALE_SMOOTH); // 设置新的大小，这里是16x16像素icon.setImage(newImage); // 设置调整大小后的图像frame.setIconImage(newImage);frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);frame.setVisible(true);Container c=frame.getContentPane();c.setLayout(null);c.add(videoJPanel);c.add(videoText);c.add(audioJPanel);c.add(audioText);c.add(area);c.add(jl);c.add(jlPosition);c.add(comboBox);c.add(audioComboBox);c.add(option1);c.add(option2);c.add(jt);c.add(b);c.add(selectButton);c.add(exchangeBt);
.............................
//converter.processLoadingAction(exchangeBt,frame,b,selectButton,fileList,comboBox,jt,option1,option2,audioComboBox);c.setBackground(new Color(222,184,135));}

接着启动main方法接口了。

效果如下：
