Question

我想使用ffmpeg库合并两个mp3文件。但不是succsesfull.Following是我的代码

GeneralUtils.checkForPermissionsMAndAbove(MergerActivity.this, true);
LoadJNI vk = new LoadJNI();
try {
    String workFolder = getApplicationContext().getFilesDir().getAbsolutePath();
    //String[] complexCommand = {"ffmpeg","-i", "/sdcard/videokit/in.mp4"};
    String[] complexCommand = {"ffmpeg -i \"concat: /storage/internalsd/Music/02 Love Dose.mp3| /storage/internalsd/Music/02 Love Dose.mp3\" -acodec copy output.mp3"};

    vk.run(complexCommand , workFolder , getApplicationContext());
    Log.i("test", "ffmpeg4android finished successfully");
} catch (Throwable e) {
    Log.e("test", "vk run exception.", e);
}

错误日志显示在

之后

vk run exception.

    at android.view.View$PerformClick.run(View.java:18437)
    at android.os.Handler.handleCallback(Handler.java:733)

请帮助解决错误。

确保首先拥有权限。

试试这个 -

ffmpeg -filter_complex "amovie=file1.mp3 [a0]; amovie=file2.mp3 [a1]; [a0][a1] amix=inputs=2:duration=shortest [aout]" -map [aout] -acodec mp3 file_merged.mp3

修改1：

concat协议是这样的：ffmpeg -i 'concat:input1|input2 -codec copy output

我认为您出错的地方是，在您的文件名中，在填写文件名之前加上space，即02 LoveDose.mp3
