I'm having trouble locating BlackBerry techical specifications and their website is a mess. They also don't have a number that I can use to easily contact them.
This isn't exactly a coding question, but what does the BlackBerry audio API look like, and where can I get technical specifications on audio? Specifically, I'm trying to find out more information on Audio-In, specifically, through the Mic-In on the 3.5 mm jack.
Unfortunately, before I can proceed, I need to know such things like sampling rate, data width, etc.
Direction to the right resource or if you know off of the top of your head is appreciated.
I couldn't agree more, the BlackBerry site is a maze!
You can find the API here.
I am not sure about the audio side of BlackBerry I'm afraid but check out
the BlackBerry support forum as there are some guys who work for RIM on there.
How about this post?
I am sorry I can't help more.

I'm researching AR frameworks in order to select the best option for developing conference call/ meeting application for ODG glasses.
I got only a few directions for selecting a framework:
Performance of video streaming (capturing and encoding) must be watched closely to avoid overheating and excessive power consumption,
Should support extended tracking and
Video capturing should not be frame by frame.
I have no experience with AR field in general, and I would really appreciate if you can let me know your opinion or to give me some guidance on how to choose the best-fitted framework.
For ODG, you should use Vuforia according software details :
Qualcomm Technologies Inc.'s VuforiaTM SDK for Digital Eyewear
Vuforia supports extended tracking. According to what you are asking, you'll need more than just an AR SDK. You'll need to identify what you want exactly. Do you want an application that let the user see with who he's talking or do you want some holographic stuff? Depending on what you want, maybe smartglasses isn't what you need and at this point you should try to learn more about the differents SDK out there. I suggest you to look at this and that.
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.
here are some links

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.
Nuance made a major announcement on 8/6/2012 about their new Nina technology, but the SDK does not seem to be available. I don't even find any documentation beyond marketing stuff (video etc.). Does anybody know how to use this SDK, or when/where it will be available ?
They made the announcement but it doesn't mean the product will be available soon for a wide audience. They just started one partnership to prove the technology work and you need to be a very big client in order for them to return your calls.
Luckily, there are other speech recognition and NLP providers out there. You should better check the ones who have the product available.
It looks like the main site is http://dragonmobile.nuancemobiledeveloper.com/public/index.php?task=home
I am developing an app that tracks the user's position. I do not know how to read gps location data from the BlackBerry.
Sure, it's all just a google search away:
the essential bb api (open on the net.rim.device.api.gps package) is always a good place to start and a lot of helpful info in the blackberry support forums. And there is more where that came from.
I noticed that such broad questions are frowned upon in the stackoverflow community and you have a much bigger chance getting a helpful response if you present a more specific problem that can't easily be solved by using a search engine.
I've been googling about how to accomplish oneline chat for rails application and I've implemented a text chat version using Juggernaut. But for video chat, I only find flash&red5 might be a solution for me, but it's flash and java, which I'm relatively not good at. Is there a better solution?
I have researched this a little and the options are not great.
There are some nice-looking packages that cost real money. Tokbox.com, ooVoo (http://www.oovoo.com, looks free at first but free version has limits), VideoWhisper.com looks interesting -- they seem to sell a 2-way video chat package for a one-time fee, but it is PHP-based.
A simple Flash-based solution is definitely a good way to go. Flash has good video support and virtually everyone has it installed already. It's not that hard to learn enough Flash basics to do a simple 2-way video chat (see http://www.derekentringer.com/blog/fms-video-chat/ for an example of a trivial video chat script that is something like 30 lines of code). And you don't need to learn Java to use Red5 unless you want to customize it -- Red5 is the open-source video streaming server that makes it so you don't need to buy really a expensive Adobe Media Streaming server system. You just need to learn enough to set it up and get it running.
I'm certain there's an open-source or low-cost Flash script out there that handles a basic 2-way video chat, but I have yet to find it. If anyone does, please post it!
Here is a rails implementation of tokbox:

Try using Raydash. There is a rails gem available at https://github.com/gersh/Raydash-Ruby-on-Rails. You just need to register at http://www.raydash.com to use it.
