How can we program a circular buffer for Blackberry?
Are you looking for something like these, from the OstermillerUtils library? I don't think it's written for J2ME but if it doesn't compile it would at least give you some code as a starting point.

I want to get stream of an ip-cam on my iPhone/iPad and want to display it on screen. By R&D i found that ffmpeg is the only way to achieve it but i found nothing on ffmpeg. Is there any other way to achieve it or a confirmed way to get compiled ffmpeg on mac please mention that. Material regarding how to use ffmepg or source code example will be highly appreciated.
Is there nothing built-in framework to achieve it if not then please mention if there is any free framework/sdk to achieve this functionality.
Thanks
There are actually a few.

I am sure if you google you can find more.
I cannot only address the first one, because that is ours, but I didn't want this to sound purely like self promotion.
I'm a complete newbie at Appcelerator's Titanium SDK, so I apologize in advance if this question has an obvious answer.
Is there any way to change a sound's pitch in real-time using appcelerator? Is there a module that can do that?
When looking for the answer, I found out about some objective-c libraries (dirac-2, for example) that can do that. Is there any way to interface to such libraries through Titanium without a dedicated module?
After some searching, I found a module - Zero Latency Sound - that can control a sample pitch in real time.

Also, this module's support is commendable.
I am currently running Kobold 1.0.4 and cannot work out how to use Box2D using Objective-C, any help will be appreciated.
I have looked at the Box2d example project with kobold but it uses only c++ i need to do it in objective-c as i am not really confident playing with both.
Change extension of your source files from *.m to *.mm to be able to use c++ classes in them. It will allow you to create and manage box2d objects in your objective-c code
Box2D is written in C++ so one way or another there's no getting around it. Since Box2D's code does the heavy-lifting, the amount of C++ code needed to us it is quite small, you just need to get the boilerplate up for collision handlers and then the code you fill it with can be as objective-C as you want.
If you want something that helps get geometry into your app, PhysicsEditor is a good tool and they have a plist exporter and provide an objective-C class for loading the data. It takes care of a lot of boilerplate, and if you want to do collision geometry for anything interesting it's very helpful.
I'm searching for a MonoTouch wrapper (or a complete port) of this library:
https://github.com/gdawg/uiimage-dsp
UIImage Image Processing extensions using the vDSP/Accelerate framework.
Fast Image Blur/Sharpen/Emboss/Matrix operations for UIImage.
REQUIRES IOS 4.0 and The Accelerate framework.
Thanks in advance.
You won't find bindings for it - at least not in it's actual form. Quote from the URL you supplied:
Copy the UIImage+DSP.h and UIImage+DSP.m classes into your project
So it's not yet a library. Someone could maybe it one from the code but, until then, you won't find bindings for it.
As for a complete port the next quote
these aren't quite as fast
makes it sounds like translating the code to C# (lots of array, bounds checks... even if they could be eliminated with unsafe code) is not the best option. I suggest you keep looking at another (OpenGL-ES maybe?) solution - like your previous question here: How to do a motion blur effect on an UIImageView in Monotouch?
Maybe even add a bounty once you get enough reputation points :-)
I wrote a native port of the blur and tint UIImage categories from WWDC for Monotouch.

It uses the Accelerate.framework - you can possible extend on it if it doesn't exactly suit your needs.
I'm looking for some unit or sth like GDI+ that doesn't need runtime libraries. I just need text and image effects.
GR32_lines and GR32_text by Angus based on Graphics32, plus Clipper - native Delphi clipping lib also by Angus. Both are free, open source and EXCELLENT! Angus is a good guy in the Delphi community.
Take a look to AggPas good for 2D drawing and antialiasing text
Graphics32 perhaps?
You will need to be a bit more specific, I'm afraid - the question is very vague.
You could try Graphics32. I've been very impressed with it for my needs.
