I want to Implement the Music Tracker as like below image.
I want to implement it in to the iphone. So is there any Music API or any Sound Library available to implement it in to iPhone ??
Please help me regarding this.

This isn't a 'tracker', but is a visual representation of the frequency domain for a given time period during playback.
You'll need a library that can do Fast Fourier Transforms (FFT) such as this.

Hello I would like to add a few features to a video player, however I do not have enough time for writing the player itself. So does anyone know any open-sourced video player that plays .MOV extension videos through internet?
There are a number of open source video players available that you can check out. Here are some links:
http://openvideoplayer.sourceforge.net/
http://www.videolan.org/vlc/download-ios.html
https://github.com/ign/VideoPlayerKit
These should get you started but be aware that groking the code may take some time.
