iphone - Play mp3 file smoothly upon dragging a scroll using AVToolbox or openAL -

I have been fighting since so many days but I have not been able to reach any conclusion.

My problem is that: I want to play an MP3 file, but not by clicking on a play button.

That's the way I want to play it.

* is a slider that I can drag with a finger, I want to play MP3 with frequency with which I'm pulling my finger (or the speed at which I Dragging my finger so that it could give the effect of fast forwarding (fun type) or if I slowly pull the slider, the output will be slowed

The problem is that the production of sound is not coming smooth The irritating sound I want to be smooth output.

Please help. Any suggestions Please, currently I am using AVAudioPlayer and passing the time value based on the slider input to run the file. (Although this is not possible) I think it is only possible using OpenLAL and there is no other way. Because of the use of OpenLL we can modify the frequency of the sound file (pitch)

Someone give me a link I'm OpenL

Help !!

You will not be able to do it with the aviideo player because it does not support pitch operation.
You can load and decode the entire track in memory for playback with OpenEle (which supports the pitch), or you can load and decode loading / decoding and audio units in real-time (very low level, More complex, though) can change.

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -

I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device. Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen. You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!

Git Bash script to check whether repo has any commits? -

I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this? Something like this will appear in the proxy code. #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?

This is your show-ref . You ask "Is there anything in this safe / head in the safe?" I ask, "what current head exists?" In practice, both of these are fair tests, because once you have a branch, so to achieve the HEAD , some mock values will indicate manually lack of editing It is very diffic...
