FFmpeg 只显示输入文本中的数字（没有字符，只有数字）错误=13，权限被拒绝

Question

我试图使用 FFmpeg 创建 gif 格式的视频和音频，在 Android 10 上，不起作用该代码在 android 9 及以下版本上运行良好，而在 10 及以上版本上运行不正常 Cmd，正如我提到的，它在 android 9 及以下

上工作得很好

 String[] cmd = new String[24];
    cmd[0] = "-i";
    cmd[1] = audio.getPath();
    cmd[2] = "-ignore_loop";
    cmd[3] = "0";
    cmd[4] = "-i";
    cmd[5] = image_path;
    cmd[6] = "-vf";
    cmd[7] = "scale=trunc(iw/2)*2:trunc(ih/2)*2";
    cmd[8] = "-filter:v";
    cmd[9] = ayat_drawer + qara_draw;
    cmd[10] = "-vcodec";
    cmd[11] = "libx264";
    cmd[12] = "-pix_fmt";
    cmd[13] = "yuv420p";
    cmd[14] = "-r";
    cmd[15] = "25";
    cmd[16] = "-preset";
    cmd[17] = "ultrafast";
    cmd[18] = "-c:a";
    cmd[19] = "aac";
    cmd[20] = "-b:a";
    cmd[21] = "128k";
    cmd[22] = "-shortest";
    cmd[23] = outputLocation.getPath();

Java代码：

 FFmpeg mFFmpeg = FFmpeg.getInstance(context);
        try {
            mFFmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
                @Override
                public void onProgress(String message) {
                    super.onProgress(message);
                    callback.onProgress(message);
                }

                @Override
                public void onSuccess(String message) {
                    super.onSuccess(message);
                    Utils.refreshGallery(outputLocation.getPath(), context);
                    callback.onSuccess(outputLocation, "video");
                }

                @Override
                public void onFailure(String message) {
                    super.onFailure(message);
                    if (outputLocation.exists()) {
                        outputLocation.delete();
                    }
                    callback.onFailure(new IOException(message));
                }

                @Override
                public void onStart() {
                    Log.d("TAG", "<ffmpeg>Started command : mFFmpeg " + java.util.Arrays.toString(cmd));
                }

                @Override
                public void onFinish() {
                    Log.d("TAG", "<ffmpeg>Finished command : mFFmpeg " + java.util.Arrays.toString(cmd));
                    super.onFinish();
                    callback.onFinish();
                }
            });
        } catch (FFmpegCommandAlreadyRunningException e) {
            Log.e("MAS" , e.getMessage());
            e.printStackTrace();
        }

我认为是因为 FFmpeg 使用 Asynctask 并且它已被弃用

我找到了使用此代码的解决方案： https://github.com/umeshlakhani7170/ffmpeg-video-editor-android

FFmpeg 只显示输入文本中的数字（没有字符，只有数字）错误=13，权限被拒绝
