how import AndroidAudioConverter & IConvertCallback?

if import cafe.adriel.androidaudioconverter; then will get a lot error as follows : MainActivity.java:27: 错误: 找不到符号 import cafe.adriel.androidaudioconverter; ^ 符号: 类 androidaudioconverter 位置: 程序包 cafe.adriel

AndroidAudioConverter.load(this, new ILoadCallback() { ^ 符号: 类 ILoadCallback 位置: 类 MainActivity ...

Here are the logs

Could not find com.github.adrielcafe:ffmpeg-android-java:2a627f6ecd. Required by: project :app > com.github.adrielcafe:AndroidAudioConverter:0.0.8

     Suggestion tried :
     
     1: Added dependency at the app module level and maven URL 'https://jitpack.io'   at the module level.
     2: Added dependency at the app module level and maven URL 'https://jitpack.io'   at the app level.
     
     
     Nothing works. 
     
     Any suggestion how to fix it?

Hi. I stumbled across this library and it looks very promising.

I added this to my application:

public class App extends application {
    @Override
    public void onCreate() {
        AndroidAudioConverter.load(this, new ILoadCallback() {
            @Override
            public void onSuccess() {
                android.util.Log.d(TAG, "FFmpeg is supported by the device. Succesfully loaded AndroidAudioConverter library.");
            }
            @Override
            public void onFailure(Exception error) {
                // FFmpeg is not supported by device
                Log.w(TAG, "FFmpeg is not supported by this device.", error);
            }
        });
    }
}

And got the following error:

W/Application: FFmpeg is not supported by this device.
    java.lang.Exception: Failed to loaded FFmpeg lib

I then looked into the source code of your project and found that the load method does this:

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() {

                        }
                    });
        } catch (Exception e){
            loaded = false;
            callback.onFailure(e);
        }
    }

So, I pasted that into my code and replaced catch (exception e) {...} with catch(exception e) {e.printStackTrace();.

I ran that and got the following error:

E/FFmpeg: issue in coping binary from assets to data. 
    java.io.FileNotFoundException: x86/ffmpeg

        at java.lang.Thread.run(Thread.java:923)

So this means that FFmpeg is not installed I guess?

I looked into the source code of the ffmpeg-android-java and found where the FFmpeg file should be located. I ran:

System.out.println(this.getFilesDir() + File.separator + "ffmpeg");

And got as output:

I/System.out: /data/user/0/be.ksa.voetje/files/ffmpeg

I then ran

System.out.println(new File(this.getFilesDir() + File.separator + "ffmpeg").exists());

And got false, so the file does indeed not exist.

I'm unfamiliar with the FFmpeg library, so I really have no idea on what I should do now. If you could help me with this one, that would be wonderful.

Thank you in advance. Jonas

I am using this code to convert my mp3 file in m4a because I want to merge audio and video files and using mp4parser library for this. But I red somewhere that mp4parser only works with m4a audio format. When executing this code I am getting this error "/data/user/0/com.jiviz.m4a: Permission denied".......My audio file is in string format..Log - V/Mux-------: ======/storage/emulated/0/DCIM/Jiviz_2021_02_01_07_15_33.mp4======/data/user/0/com.jiviz.app/files/songs/312mp3
