Karaoke App videoke

1- Already have all music videos in MP4 format. only need to play the file, don't need to sync music with lyrics. 2- Before the karaoke app, need a app to encrypt the mp4 so only the karaoke player can decrypt and read. 3- The karaoke player 3.1- Main screen with music videos playing in background or MP3 with custom background when waiting for the user input karaoke song code. 3.2- All karaoke music will be named as [login to view URL], if i can choose the encrypted extension, i want to choose. 3.3- The user will input the music code, the code from the filename, and press enter, or a key from the custom settings. 3.4- While the user are singing, another user can input a new song code, and the music will enter the waiting list, if the user press the enter for N seconds the music enter in number 1 on the waiting list. 3.5- Keyboard Settings page, here whe choose each keyboard key for each function. 3.6- Settings Karaoke mode Free mode (unlimited sing) Credit mode (1 credit per sing) (custom key to add credit) Score ON/Off N seconds key to jumb the music to first music on waiting list ON/OFF Set karaoke screen always upfront all windows apps Always Show Search bar ON/OFF Music folder path selector 3.7- In main screen when waiting for user to input code, search bar always visible. after karaoke start, search bar desapear, when another user start to input another code, the search bar appear. 3.7.1- Search bar info 5or6 digits music code when user input music code the music info appear next to the code Music info Artist Music name Lyrics start line 3.8- After music ends, if score settings are ON appear a score screen. if settings is off, go to next music on list, if don't have waiting list, go back to main screen and start to play a random backgroung video. 4- The karaoke app use licence to activate. The activation will be linked to user harddrive serial. 5- When the user open the app the first time, the app will read the hdd serial and generate a encrypted text, and the user will send this text to me. i will need a serial generator, that will read the text from the user, and generate a serial, this serial i will send to user, and user will activate the app. 6- I want the source code, and a way to obfuscate source code before create the final app. 7- All the screens i want to be editable outside the source code, Background, music search bar. The search bar i will send you a sample and all music info database will be inside a file, that can be updated later. I will send uou a sample, but if you find a better way, it’s ok. so in few words 1- mp4 to encrypted file 2- karaoke player app 3- serial generator 4- a way to obfuscate code before release. i khow the info maybe confusing, but my english is not so good. thank you for your patience.
