i`m new to Symbian , my goal is to playback mp3 file stored on phone with my MIDLet.
Is it possible? I do not know how to do it - i'll be very grateful for any help.
It's possible with the APIs provided by J2ME.
First step. You need to verify that your specific phone has the capabilities required. Install any free J2ME mp3 app like KD Player (http://en.wikipedia.org/wiki/KD_Player) and try using it on your phone.
Second step. If your phone can play mp3 music using the free app but you still want to create your own, you need to find a good J2ME resource like this:

To be honest, that second step is probably a bit too much especially if you're the kind of person who asks first instead of using Google. Sorry.

I created a game in flash, for android(I know flash is dead, but was the only platform I knew how to code a game). It's based on matches, I did the AI and the game works very well offline.
But now I want to make it online and I never developed anything for web, like websites, webservers. I do not even know what SOAP, REST and this methodologies are.
So what do I need to learn to develop something like this? Here are the requirements :
I want to create a "room" with your facebook friends that are online in the moment.
In this "room" you can invite them to play a match.
The information that is passed client to client is only two points in the cartesian plane(e.g., {(1,2), (3,5)}) and the information that the game may have ended.
It's important to notice that the server must hold connections from
cellphones. The information passed is from cellphone to cellphone.
Develop the whole game in another language or platform is not an option. This is my first game that will be published, so its more like an learning exercise. I dont know PHP nor Python, but I can learn it.
Thanks.
there is a service called Flox (https://www.flox.cc/docs/getting-started) which has a AS3 integration, take a look at it, may help you
I have a final project abount database design this semester. And my teacher gives us many tasks for alternatives, such as Student Information Management System, Airline Reservation System and so on. However, I want to design such a player that it allows users to upload their own works and share together. Of course it also provides download service. I'm a sophomore this year. I'm familiar with c++ programming, but do not know much about network programming. Furthermore, I learnt T-SQL this semester and also did some works on MySQL in java(course in this semester, too). My idea is here (I have drew a picture):http://tmjfzy.blog.163.com/blog/static/66447025201242553045/
I need some advice about network programming. Could you give me some to help me realize my imagination? Thank you :-).
So, you're basically reinventing YouTube but with dedicated client?
Actually it's very easy to start without any clients or C++ : all you need is a server with MySQL, Apache and PHP. I recommend WAMP server if you're on Windows. FlowPlayer is a flash video player quite easy to integrate, but today using HTML5 video features should be a better idea. I believe you can have the reference Web system up and running in about 3 to 6 days.
(I'm also a C++ programmer and I had no problem with learning enough HTML, PHP and JavaScript to do very similar thing ).
Once you have a system up and running (possibly with limitation on video file format) you can design and implement API. From server side it's nothing more than PHP files, just returning data in your format of choice (eg. JSon, XML) instead of generating HTML.
With server-side API done, you can start working on client. Registration, login, upload from file and download to file should go first. Once the client can get the video files, you can implement a player. A streaming player goes next. If you encounter problems with playing back the video files, this is good moment to break compatibility with web version and change video file format. Now that you know what playback formats are supported, you might implement converting before upload. (Conversion makes sense if you want to have all files on server in one format. Otherwise it's not really usefull: if a client can convert a video, it should be able to play it back. This means all other clients also should understand the format and be able to play it back.)
At this point you can consider rewriting the server. Or other student can be writing the server in the same time as you're busy with client.
Having working Apache-PHP reference all the time makes such parallelism a breeze.
All the above requires using HTTP as underlying protocol. I think Qt has built in support. If not you can use some library (like cURL) or implement it from scratch on sockets.
Eventually streaming, like RTP+RTSP, can be added for playback.
If you feel really adventurous, you can start designing your own protocol, but this is the very last step, after having both own client and own server working flawlessly on hand-implemented HTTP.
Ok so my new gig is high performance video (think Google streetview but movies) - the hard work is all embedded capture and image processing but:
I was looking at the new MS video offerings to display content = Windows Media Foundation.
Is anyone actually using this ?
There are no books on the topic.
The only documentation is a developer
team blog with a single entry 9 months old.
I thought we had got past having to learn an MS api by spying on the com control messages!
Is it just another wrapper around the same old activeX control?
I read the Media Foundation Programming Guide, and it's as complete as everything else is w/ MS, in that you have all the information you need, no clue on how to find it, and no idea what's important when.
I'm trying to use MMF, but I'm currently not getting anywhere, and am thinking that going back to DirectShow might be the better approach as there is more example code with explanations.
No, it does not appear to be just another wrapper around the same ActiveX controls.
Did you read Media Foundation Programming Guide? It looks pretty complete.
To get started with Media Foundation you might want to read this. Media Foundation was first introduced in Windows Vista. Thus, you must have Vista or later versions of Windows to develop Media Foundation apps. If you are targeting Windows XP users then, D-Show might be a better option.
I am trying to build an iphone app that connects to an IP camera. The IP camera is windows based to i need to create a server using c++ and then stream the video to the iphone app.
Can anyone tell me the best way in going about this task. I am new to programming so a dummies type guide would help.
Thanks
Inam
Go to the ITunes store and download a free app from Avigilon. You won't be able to see any video unless you connect to a system but it'll tell you what ports and user information would be needed. There are gateways and streaming methods involved as well. Not a situation where a new developer will have a lot of success.
Your question is rather too broad to fit into a comment box. It seems, and correct me if I'm wrong, that you're basically asking for someone to write the applications for you.
Instead, if you're a complete beginner, you'll want to first learn how to program for the plaform.
The StackOverflow question Howto articles for iPhone development, Objective C will help you get started with programming for the iPhone.
Once you have the basics down, you might then ask more specific questions.
I've been looking for a while for a good web page embed-able mp3 player. I've considered going with the Wimpy Player, but it appears to have problems with Flash 10, and their customer support is unresponsive.
My requirements are pretty simple, I want to be able to play/pause/rewind audio. I'd also like to be able to embed the player multiple times on the same page as well as be able to play a playlist of multiple mp3s.
Any products other than Wimpy that I should be investigating?
Any advice is much appreciated.
Check out jPlayer.
Did you try the player from longtail?

Work for me, and i belive is better as it dosent user HTML5, which is not fully supported across browsers.
