how to make a 3g video talk software?
what kind of api do I need?
video stream, camera api?
Is there anyone can tell me how to make?
what do I need?
Thanks...

well there is no actual inbuilt API for that...
Streaming in J2ME is a pretty complex thing to achieve... Through the JSR-135 API you will be able to play sounds and there is even an API for the camera (cant remember which one though)...
But all this is far from one integrated API which can do all these things in a decent manner... For example the MMAPI (JSR-135) does "support" streaming through rtsp... Apart from the results (which I catalogue as dreadfull) it's not like its gonan work on every device, some do supprot rtsp through the MMAPI, others only support rtsp through a native Player (RealPlayer mostly)...
SO it's definitely no easy task, and if you're just starting out with J2ME then you might be in over your head with such a project...

Thanks.
But now I have a question when I use MMAPI-Camera api: I try to use the front camera to take photos in one second.
But there is a warning whcih need to press when taking one photo, result in that I can't catch a series of photos.

I try to sent a series of phtos to make video talk come true. Is it the right way to do?
And do I need a c/s or p2p?

And what kind of technology does iphone 3g video talk need?
And which books can I find these info

[Tiger79]

well I guess you are completely in the worng forum to ask that right ? ;)
Apple Iphone has nothing to do nor with J2ME nor with Nokia...
Those are completely different platforms, which aren't even compatible with each other...

I know ,now I just lost my way. I want to find something useful from iphone.
I want to know how to make a 3g video talk.

well streaming is always been a problem with J2ME, simply because it's not supported from the platform itself, with exception of rtsp that is...
unfortunately you cannot compare the Iphone as a platform with MIDP 2.0
Obviously there is the age difference (MIDP 2.0 is pretty old, something like 6-7 years whilst the iphone platform is 2 years old now)...
Personally I would advise you to try to make such an application in C++/Symbian... This will limit your application to S60 devices, but if you check how many S40 actually have 3G chips in them you won't be missing that much of the market ;)

thanks. c++ has some api with 3g video talk technolgoy? I am not familiar with c++.

[Tiger79]

no, I don't expect ist has an api for that...
If I were you I would'nt hope to find such an API really fast, Symbian and J2ME aren't really platforms for which many API's are being developed outside of the manufacturer's implemented api's... So there aren't many "community" API's included within the devices, maybe you can find some (paid ones?) online from 3rd party developers...
I'm afraid that if you want something that really really fits your needs you will have to do like everyone else : get your hands dirty and start programming it yourself ;)

also c++ is somewhat more complex (less readable, and the hell called pointers/references) than Java, so keep that in mind, you will need to invest a good portion of time just learning the language... Many times asking code and copy-pasting that won't result into something that actually works, or at least not as easily as in java...
