Reverse libETPlayer.so and Decode the DNT file.

I have a MagicSing Karaoke app. In this app, [login to view URL] is used. In the [login to view URL], DNT file will be downloaded and decoded, played in player. I think DNT file is stream file and it contains midi and lyrics. You can get a sample dnt file and [login to view URL] file from this url: [login to view URL] [login to view URL] Attached files are midi and lyrics files. I need to get original data from DNT file by analyzing the [login to view URL] in IDA Pro. If u can get original data or find the decoding algorithm, Please start project. Thanks.
