I want to create a Qt program that uses the DVB-H headset to watch and record programs. I know there is already such a program on the Nokia store but it doesn't work with latest headset. I have already found this http://library.developer.nokia.com/index.jsptopic=/Java_Developers_Library/GUID-154101B4-1539-4025-9698-FC1FBF393C0E.html for using the headset with a Java app, but I want to know if there is a Qt version of this API that I can use. I have been looking around but I can't find one, maybe there isn't one. If you know anything about this please help.
Qt APIs for DVB-H do not exist. JSR-272 is the only option on Symbian.

Does anyone know how to integrate the Playstation Eye with Labview? Can a driver somehow be used to allow Labview to recognize it as a webcam?
You should be able to do this with vision (install IMAQdx and Vision Dev Module)- it seems to be DirectShow, which IMAQ can do- or try out the code found on this page: http://www.labviewforum.de/thread-21279.html - it uses the original dlls.
as there are NO official dll´s for the PS3 Eye on Windows, the ONLY Option is to use the 3rd Party drivers from Code Laboratries or directly interface the Hardware via USB-RAW commands. Code Laboratries PS3 Implementation however does not seem to be 100% conform with the Direct Show standard. You can get a PS3 Eye to work with Labview (via Direct Show and IMAQ), but you will be limited by the usable framerates.
I tried to interface the dll from code laboratries directly, but got stuck on a stange error with the second function i tried (see the already referenced Thread http://www.labviewforum.de/thread-21279.html). However it seems as for now there is a Vi Package available for the PS3 Eye to support LabView under OSX with the full available framerate. More Information can be found here:

Hope this helps.

Is there currently any API (public or private) that will allow a 3rd party Mac OS X application to stream audio to AirPlay receivers? Airfoil by Rogue Amoeba Software seems to be able to do this, same goes for Erica Sadun's AirFlick, but I was unable to find any source code that would demonstrate how to do this. Any pointers are appreciated!
Here is an open source ruby implementation. It's pretty straight forward. https://github.com/elcuervo/airplay
It turns out AirPlay audio streaming is possible as of OS X 10.8 using public APIs, but wasn't really documented anywhere. Joris Kluivers wrote a great blog post on how to get it going.
There are a couple of open-source RAOP players available; I haven't tried them, so I don't know if Apple has broken them since they were written.
Mountain Lion (OS X 10.8) has added AirPlay support in the sound settings. The user can choose to send the local sound output to an AirPlay device. However, I don't think that you have access to any API within your app.
There are some libraries available to implement AirPlay, but know that Apple will reject your app if you try to publish it on the App Store. At least, that's what happened to me.
I wrote a node.js module to support AirPlay. Even if you don't use node, you can just pipe your audio data through stdin.
https://github.com/lperrin/node_airtunes/
I don't think it's available. At least not in versions prior to 10.7.
I'm guessing that Airfoil uses something like DVD John did a while ago when he cracked the Airport Express key payload. He released the code (C#) you should be able to find it but it's pretty cryptic.
I'm not aware of what AirFlick uses but you could always try pinging Erica, she usually shares her stuff.
Someone recently managed to obtain the AirPlay private key which allows you to have your program listed in the AirPlay menus on devices on your network.
You can read about it here. There is also an open source project linked from that page.
http://mafipulation.org/blagoblig/2011/04/08#shairport
Be aware that obviously any application you create will never be approved by apple and the private key could potentially be changed in a firmware/software update.
I'm learning Factor and I thought it would be great to have a small program to capture images from the webcam that comes with my mac pro. I know every webcam will be very different but sounds like something I should be able to do. I want to create a library with support for Mac, Linux and Windows. The problem is that I'm not sure where to start.
Factor-based answers are welcome but I'm looking for the language agnostic solutio. When I google for it, all I get is programs that capture images. I want to learn how to interact (in the 3 big operative systems) with the drivers I guess.
I think the only clue I have is the ioctl wiki page. How would you start such a project? What kind of google keywords would you use? Books?
It's not clear if you want to write a driver for your particular webcam or a library that makes talking to the existing driver easier.
If you want to write a driver for your webcam, you probably want to investigate libusb for Mac and Linux and libusb-win32 for Windows. You would need to understand the protocol that your webcam talks, though. You could probably read the source code for the existing Linux driver (assuming there is one, which is pretty likely).
As for Google search terms, you might try "video capture" and maybe looking for Python/Ruby etc. code or Open Source programs will get you code you can look at to see how to do what you want to do.
Perhaps if you describe in a little more details what you're trying to accomplish someone could give you better suggestions.

Hello everyone,
I recently bought a Sony Ericsson mobile phone and I would like to add a missing feature myself. In fact I cannot actually disable Internet connection in an easy way when roaming, which cost me a lot of money last time I moved away ... So I would like to develop a little application that would just replace the actual Internet configuration with a fake configuration to avoid auto-connections.
So what I would like to know is how can I access programmatically to my phone settings? I know that Sony Ericsson provides a SDK to run Java applications on its customised JVM. So what I am actually looking for is to know if they extended the J2ME functionality to fit their devices requirements.
This is not well documented so I am asking this question with the hope that someone here already had experience with development targeted for Sony Ericsson devices.
Thanks.
NB: This is a Sony Ericsson Elm which is based on the Sony Ericsson OS with SE Java Platform 8.5.
Edit: I accepted QuickRecipesOnSymbianOS answer as it gave me a clue on the only feature that could have helped me, but which is unfornatunately missing. The Sony Ericsson Java Platform is the only API I could use to develop real programs on my phone. But the JP-8.5 does not implement the JSR-307 package which could help me in managing APN. Thanks everyone for your help.
Well, I hope you got the great Vivaz phone, not the Satio.
In order to learn about Symbian OS C++, first go to the Foundation website.
Relevant plug: the latest introduction to Symbian OS C++ in book form is Quick Recipes on Symbian OS
For now, you won't find a better way than Symbian OS C++ to manipulate your handset access points.
JavaME simply doesn't have the correct APIs for this, at least not until JSR-307 is implemented.
I believe Qt isn't integrated quite tightly enough just yet either but that should change soon enough. Keep an eye on it.
Extending the Symbian Python runtime to do what you want would require some Symbian OS C++ anyway.
Yes you will need to use Symbian C++ to modify the CommDB, which holds the list of connections. It is quite painful to work with it directly, but there are some utility classes that can help you out. Take a look at CApSelect, CApDataHandler and CApAccessPointItem, all in the developer library.
And yes, these will work on all modern Symbian handsets, independent of brand.
Note: My answer below assumed it was about a symbian device. Since it was actually a J2me device none of the below applies
The easiest way to achieve what you want to do is probably to just remove all the "destinations" when you want to prevent auto connections. Otherwise the device will test each destination in turn until it finds one that works.
You can also set up your destinations so that they are not allowed to be used automatically. This setting must be done individually for each destination.
You can also group your destinations and set one of the groups to the default. If you set the default to an empty group you should not get any automatic connections.
Note that I have not tested any of these methods myself. When I roam I turn off automatic updates in the apps that use them. Some apps can even detect when you are roaming and avoid auto connects.
There are S60 apps available that improves the connection management of vanilla S60, but I do not know if any of them can help you with your problem.
If you are dead set on doing the programming yourself you have to use the C++ SDK for Symbian S60 available from Forum Nokia. Java ME does not allow you to manipulate the destinations of the device.
The Elm device should have (I haven't verified this) the access point API originally designed by Nokia. Not sure whether you can use it for the purpose you want though. The J2me developer guidelines available from developer.sonyericsson.com should have all the information you need.
I have a Symbian 9.1 handset, Nokia E65, based on Nokia S60 series UI. I'd like to build a simple, full screen, graphic application. It should be able to display some text and pictures and have a basic interaction from the keyboard. That's for me only, not to be deployed.
Now, what do you think is the quickest and most painless way to have it done?
I have the following skills:
- HTML, PHP, ASP.net, JS
- ASP.net and C#, Silverlight
- Java, but mostly for networking, not UI
- Some C++
I have downloaded the Nokia IDE, but it is scary at first sight :)
Any tutorial or example are welcome!
Edit:
In particular, two questions:
is there a possibility to make a stand-alone flash application for that handset?
how about the QT mobile version?
For your device, definitely use Python for S60. It is much easier to start with than Symbian's C++ SDK and in case you ever need more low level functionality than python gives you, you can write small modules in c++ and use them in your Python program.
For a simple application like the one you are describing, Python will do just fine. You don't even need any of Nokia's IDEs / tools on the PC, you can just write the code in any text editor, copy it to the phone and test it live.
As others have mentioned, other options include:
Symbian C++ SDK : As you have discovered the tools and not the most intuitive to work with, development is not straight forward either.
Nokia's WRT : Using javascript/css/html, but it is not available for your phone.
Qt : Not available for your phone.
Java Me : Probably your second best option, your code will be slightly larger but more protable. The tools are not as straight forward as with Python, but definitely not as complicated as with Symbian.
If you think you may like to do some further development on the Symbian platform in future, I'd strongly suggest looking at Qt. Unfortunately, however, you can't use it on your E65, since Qt requires S60 3.1 or higher. (The E65 runs S60 3.0).
Since Qt coding in done in C++, you also have access to native platform APIs if required. For most apps however, the (considerably more user-friendly) Qt APIs provide all the functionality you need.
Depending on your background, the learning curve may be steeper than using Java or Python, but the pay-off is that you get access to a very powerful toolkit. And of course, as long as you use only Qt APIs, your app should be easily portable to other Qt platforms if necessary.
Go for Java ME.
All the things you list in your post is possible to do in Java.
The Symbian SDK for C++ can be downloaded here.
NSBasic is another option.
Kindness,
Dan
May I suggest Python? For newer Symbian handsets I'd recommend Web Runtime (WRT), but it is not supported on good old E65.
I'm obviously biased but I would suggest getting the 2D graphics example code from the "Quick Recipes On Symbian OS" book:
If you know HTML and JS already, you should be able to write a Web widget for your Symbian device pretty easily, using the tools available through Forum Nokia. More info here:
http://www.forum.nokia.com/Technology_Topics/Web_Technologies/Web_Runtime/
These widgets are standalone full screen applications that use the device WebKit browser engine for rendering and UI. You can also use keyboard inputs and customize the softkeys if you wish.
