How does one create .flv files on the iPhone?
I am aware of ffmpeg (with its LGPL restrictions). But are there other APIs that have been ported to iOS?
This seems like a strange question. .Flvs don't 'live' in the iPhone universe. They're not supported under iOS.

I am new to the iPhone development, I need to develop application in which I can load SWF files (shock wave file). I have done lots of research but I couldn't get it to work. How do I load it on the iPhone ? if it's not possible, what alternatives do I have ?
There is no Flash player on iOS and no other solution to play Flash in your app. However, you might want to look into Adobe AIR for iOS which is able to produce iOS apps.
The iPhone doesn't support flash.
iOS Doesn't support Flash so you won't be able to launch a swf. If you have the source for the SWF you could consider building an ios app through Flash CS5+. Also, you could try porting it to haxe, which is very similar to actionscript and should allow you to build for both Android and iOS at once.
As I know there is no such application (expect Frash, which is only available on jailbroken iPhones) which can load SWF Files on an iPhone.
The only way you can go is to convert that file in an iPhone readable format, which I can't recommend as the results are normally horrible.
Otherwise I suggest to recode the behaviour of that SWF File in Objective C or something similar to that.
There is no Flash player in iOS. Even more – it is forbidden by Apple iOS Developer Agreement to deploy them (and other technologies where you may use an app to execute another executable code of any kind (SWF, Java, AIR, etc.) on iOS devices.
You can also make your own flash player.
Is it possible to view video stream (H.264 live feed) over RTP/RTSP in iPhone natively? If not, is it possible to write an application for this purpose?
Sure it is possible, in fact others have done it already, see e.g. IPVision from TTrix.
Seems that the Live555 libraries can be compiled for iOS. See this SO question:
How to configure live555 framework for iphone app devleopment?
Sure it is possible now.
Previously, RTSP is not allowed in AppStore, though someone migrated VLC to iPhone, but that app is removed from AppStore, you can only install it via jailbreak.
Now Apple doesn't insist this rule any more, so you can write RTSP player on iPhone as you will.
In face, I've done this a few months ago, migrating ffmpeg & live555 to iOS and make an app, absolutely feasible!
iOS 4.3 no longer supports playing AMR Audio Files which is horrible and completely kills my app. Some people have suggested using Opencore-amr but I'm at a loss in terms of how to compile the library and integrate it into my iPhone application.
I'm looking for any tips or help I can get in terms of how to compile the library, include/link the library in my app, and sample source code for using this library to play AMR files in an iPhone app.
I am aware of some third party libraries and open source libraries to extract ZIP files within iPhone application.
But I would like to know whether there are any default iPhone frameworks provided in SDK itself?
None that I know of. I have been using Objective-Zip and it seems pretty good for my needs. But I am deflating not inflating.
I would like to join two video files within my iPhone application using the FFMPEG library, but I can't figure out how to do this. Does anyone have any experience with this?
Unfortunatley, if you planning to release your app to the App Store, you won't be able to use libavcodec since it is licensed under GPL. However, there is tutorial in the FFmpeg docs on how join two files if that is any help.
