How to make the system display video albums under the specified directory? ?

            
Such as title, image, too, but the picture seems to be inserted into the mediastroe.images.media.insert ..... but the default picture will be copied to other directories under the camera catalog, I saw some good software can not copy the next, but also can be displayed and there will be an album inside that folder named directory, the video seems to be what the insert method. .

Those plug-in software is now also read out the video thumbnails, so will have the videos are scanned, I personally feel that it is those software failures.
A pure plug-in software should not have other functions
So if you can do a scan of the video, you put the system cache and thumbnails are reading, you can scan the video
