java - 使用 ffmpeg 编辑后的视频未显示在手机图库中

Question

我正在开发一个视频编辑器应用程序。该应用程序运行良好并可以编辑视频。但问题是编辑后的视频没有显示在手机图库中。我没这个问题我最后还添加了媒体扫描仪，但我没有成功。

这是我的视频编辑器方法

private void executeCutVideoCommand(int startMs, int endMs) {
        File moviesDir = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_MOVIES
        );

        String filePrefix = "cut_video";
        String fileExtn = ".mp4";
        String yourRealPath = getPath(VideoCutterActivity.this, selectedVideoUri);
        File dest = new File(moviesDir, filePrefix + fileExtn);
        int fileNo = 0;
        while (dest.exists()) {
            fileNo++;
            dest = new File(moviesDir, filePrefix + fileNo + fileExtn);
        }

        filePath = dest.getAbsolutePath();
        String[] complexCommand = {"-ss", "" + startMs / 1000, "-y", "-i", yourRealPath, "-t", "" + (endMs - startMs) / 1000,"-vcodec", "mpeg4", "-b:v", "2097152", "-b:a", "48000", "-ac", "2", "-ar", "22050", filePath};

        execFFmpegBinary(complexCommand);
        MediaScannerConnection.scanFile(VideoCutterActivity.this,
                new String[] { Environment.getExternalStorageDirectory().toString() },
                null,
                new MediaScannerConnection.OnScanCompletedListener() {

                    public void onScanCompleted(String path, Uri uri) {

                        Log.i("ExternalStorage", "Scanned " + path + ":");
                        Log.i("ExternalStorage", "-> uri=" + uri);
                    }
                });

    } 

我只是为了在手机图库中显示编辑后的视频。我现在不知道该怎么办。非常感谢您的帮助

after complete your video editing you must call this method.

public void saveVideoToGallery(Activity activity, File videoFile) {
    ContentValues values = new ContentValues();
    values.put("title", videoFile.getName());
    values.put("description", "video");
    values.put("_data", videoFile.getPath());
    values.put("mime_type", "video/mp4");
    values.put("datetaken", System.currentTimeMillis());
    values.put("bucket_id", videoFile.getPath().toLowerCase(Locale.US).hashCode());
    values.put("bucket_display_name", videoFile.getName().toLowerCase(Locale.US));
    values.put("_data", videoFile.getPath());
    ContentResolver cr = activity.getContentResolver();
    cr.insert(android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values);
}
