iPhone 3G S / 4 Video Camera Enhancement News

image

WARNING: this article can be highly technical and is definitely NOT meant for people that haven't ever tried hacking the camera of their iPhone 4 or 3G S. If I don't run into other obstacles (I find out something very important), the next one I publish will be meant for newcomers to iPhone 4 or 3G S enhancement. If you, however, are a seasoned hacker and/or a programmer interested in writing apps for Cydia and/or have previously used my hacking tools before and would like to know what the new versions contain, you will want to read on. AGAIN: this article is NOT meant for complete newcomers!

The new versions



Yet another great iPhone 4 video camera hack by me (v11 released with sources)!

image
Having dug deep into the configuration files and the video “hacking” of the iPhone 3G S (see my yesterday's post HERE [beware, it's quite technical and mostly meant for advanced users / programmers]; I'll also very soon post a full all-in-one 3G S article for beginners), I've found the „1080p” settings I've used there applicable to the iPhone 4 too – in addition to the default (here: true HD with full frame rate, near field-of-view and bad low-light performance) and the full sensor (high-resolution video with great low-light performance and, on the iPhone 4, greatly widened field-of-view but severely reduced frame rate).


New, vastly enhanced iPhone 3G S video recorder enhancer released (with source code)!

I've just uploaded version 1.4 of my free(!), open-source(!) iPhone 3G S video recorder enhancer tool to Cydia. As usual, add the repository „http://www.winmobiletech.com/cy” or „http://winmobiletech.com/cy” to your Cydia client and download the new version from my repository. When the development is finally finished, I'll make the two programs be available in traditional Cydia repositories so that you don't need to access it from my private repository.

Main changes in this version:

Top Reasons for Jailbreaking Your iDevices



Enhancing the video recording quality of the iPhone 3GS - Part I

image

The video recorder of the iPhone 3G S can heavily be enhanced. As opposed to the iPhone 4, where the main enhancements are “only” making the field-of-view much wider, the data rate selectable and, with pixel binning, the low-light performance much better (by sacrificing some resolution and speed), the enhancements of the 3G S camera, in addition to the better low-light performance through pixel-binning, are waaaay superior: you can greatly increase the resolution, almost to the level of the iPhone 4 or traditional cameras.



The first real(!) iPhone 3GS video camera enhancer released!

The first real iPhone 3GS video camera hack released!

I've just released the 3G S version of my previous iPhone 4-only camera hack (see http://www.iphonelife.com/blog/87/how-you-can-make-your-iphone-4-much-more-versatile-video-camera ; please check out the iPhone 4 manual for more info on how the GUI works. The 3G S version is only a bit different from the iPhone4 one, so, your learning curve won't be so steep as when starting from scratch.).


The tool allows for greatly increasing resolution and fine-tuning data rate (in Simple view) and fine-tune all parameters (in Advanced view).



A quick tip: terminal emulators and programmatic password changing for iOS

image

Back in 2008 and 2009, I've already introduced (see THIS and THIS) MobileTerminal (by Allen Porter), a local, Cydia-based (sorry, jailbreak is required!) terminal emulator you can use for a lot of things; among other things, changing the root password from the default „alpine” to something (if you do install OpenSSH) less dangerous.



This is how you can make your iPhone 4 into a much more versatile video camera

(Note that this article, as with most of my stuff, shows you not only how the camera can be reconfigured, but also shows you - how you can play back a YouTube video frame-by-frame; - how you can create and upload packages to your Cydia [an alternative to Apple's AppStore] repository and, last but definitely not least, gives you a full source-level explanation of the entire app that I've written to quickly switch between the different iPhone4 camera configurations. No one has released anything similar for the iPhone 4 or the iPhone 3GS [for which I'll also release a very similar utility in a few days] before!)



Coding tips: creating PNG (JPG) and QuickTime files – a benchmark video generator for iOS + OS X

UPDATE (09/12/2012): I've created two truly 1080p versions of the counter video. They're HERE (non-streaming-optimized) and HERE (optimized for streaming with Subler). The former has a H.264 level of 4.2 (the latter is 4.1) and, consequently,  can't be played in their Web browser. (Neither 4.1 nor 4.2 1080p60 can be synched to iOS devices directly. Playback from third-party apps using hardware decoding works, of course.) HERE's a 4.1-level version of the same file.
