Could not find ffmpeg-android-java-2a627f6ecd.aar (com.github.adrielcafe:ffmpeg-android-java:2a627f

 看看aap的build里是否添了 

 implementation'com.github.adrielcafe:AndroidAudioConverter:0.0.8'

这个依赖，有的话把它注释掉，当然，我们是会用到这依赖的，不过这个依赖里的类很少，可以复制出来一份

 我把他贴出来了，需要的直接复制一个新类

public class AndroidAudioConverter {

    private static boolean loaded;

    private Context context;
    private File audioFile;
    private AudioFormat format;
    private IConvertCallback callback;

    private AndroidAudioConverter(Context context){
        this.context = context;
    }

    public static boolean isLoaded(){
        return loaded;
    }

    public static void load(Context context, final ILoadCallback callback){
        try {
            FFmpeg.getInstance(context).loadBinary(new FFmpegLoadBinaryResponseHandler() {
                @Override
                public void onStart() {

                }

                @Override
                public void onSuccess() {
                    loaded = true;
                    callback.onSuccess();
                }

                @Override
                public void onFailure() {
                    loaded = false;
                    callback.onFailure(new Exception("Failed to loaded FFmpeg lib"));
                }

                @Override
                public void onFinish() {

                }

            callback.onFailure(e);
        }
    }

    public static AndroidAudioConverter with(Context context) {
        return new AndroidAudioConverter(context);
    }

        this.audioFile = originalFile;
        return this;

    public AndroidAudioConverter setFormat(AudioFormat format) {
        this.format = format;
        return this;
    }

    public AndroidAudioConverter setCallback(IConvertCallback callback) {
        this.callback = callback;
        return this;
    }

    public void convert() {
        if(!isLoaded()){
            callback.onFailure(new Exception("FFmpeg not loaded"));
            return;
        }
        if(audioFile == null || !audioFile.exists()){
            callback.onFailure(new IOException("File not exists"));
            return;
        }
        if(!audioFile.canRead()){
            callback.onFailure(new IOException("Can't read the file. Missing permission?"));
            return;
        }
        final File convertedFile = getConvertedFile(audioFile, format);
        final String[] cmd = new String[]{"-y", "-i", audioFile.getPath(), convertedFile.getPath()};
        try {
            FFmpeg.getInstance(context).execute(cmd, new FFmpegExecuteResponseHandler() {
                @Override
                public void onStart() {

                }

                @Override
                public void onProgress(String message) {

                }

                @Override
                public void onSuccess(String message) {
                    callback.onSuccess(convertedFile);
                }

                @Override
                public void onFailure(String message) {
                    callback.onFailure(new IOException(message));
                }

                @Override
                public void onFinish() {

                }
            });
        } catch (Exception e){
            callback.onFailure(e);
        }
    }

    private static File getConvertedFile(File originalFile, AudioFormat format){
        String[] f = originalFile.getPath().split("\\.");
        String filePath = originalFile.getPath().replace(f[f.length - 1], format.getFormat());
        return new File(filePath);
    }
}

public enum AudioFormat {
    AAC,
    MP3,
    M4A,
    WMA,
    WAV,
    FLAC;

    public String getFormat() {
        return name().toLowerCase();
    }
}

以及接口

public interface IConvertCallback {
    
    void onSuccess(File convertedFile);
    
    void onFailure(Exception error);

}

public interface ILoadCallback {
    
    void onSuccess();
    
    void onFailure(Exception error);
    
}

不知道有没有漏的，不是第一时间过来写，有点忘了，可以去查那里依赖里面的内容，先把里面内容全搬出来，在注释掉那个依赖就可以了！！！！

第一次记录，最开始弄过一次，后面再弄一次就忘记了，搞了好半天才想起来！！，新手小白的我做个记录吧
