ffmpeg使用中遇到的坑---amr轉MP3格式

amr轉mp3格式代碼附上：

private boolean convertAmr2MP3(File src, File target) {
        AudioAttributes audio = new AudioAttributes();
        audio.setCodec("libmp3lame");
        Encoder encoder = new Encoder();
        EncodingAttributes attrs = new EncodingAttributes();
        attrs.setFormat("mp3");
        attrs.setAudioAttributes(audio);
        try {
            encoder.encode(src, target, attrs);
            return true;
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (InputFormatException e) {
            e.printStackTrace();
        } catch (EncoderException e) {
            e.printStackTrace();
        }
        return false;
    }

在有的環境下報錯：

 

 

it.sauronsoftware.jave.InputFormatException
	at it.sauronsoftware.jave.Encoder.parseMultimediaInfo(Encoder.java:659)
	at it.sauronsoftware.jave.Encoder.encode(Encoder.java:840)

找其緣由：若是ffmpeg沒有加載到這個pthreadGC2.dll文件，就會報以上錯誤

解決方案：將pthreadGC2.dll和ffmpeg的路徑固定，經過

public class MyFFMPEGExecute extends FFMPEGLocator {
    protected String getFFMPEGExecutablePath() {
 
        String path = 「獲取以上兩個文件的絕對路徑」;
 
        return path;
    }
}

搞定！！！
