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,32BTIS
                    audio.setBitRate(1411100); //对于16bit
                    audio.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unsigned
        return 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：
