Enhancing the iPhone 5 video camera: now, this IS possible! – Part I

image

As the developer of several video enhancer tools for the iPhone 3GS, 4, and 4S (see THIS for more info on them), as soon as I've jailbroken the iPhone 5 with the just-released “evasi0n” tool, I started looking into enhancing its camera. (As you may have guessed, you won't have access to anything I'm going to describe if you don't jailbreak.



TUTORIAL: automatically adding video metadata to your videos using the excellent, free(!) Subler

image

In my Video Metadata bible & Roundup, I've already mentioned Subler is capable of manually editing / adding video metadata. After having been asked (thread with numerous, advice-packed posts from me) about doing the same with Subler, I've decided to publish a writeup on doing the same automatically. After all, online video metadata libraries like themoviedb.org have excellent metadata for a lot of flicks.



AVPlayer(HD) & 1080p MKV users on older-than-two-year iDevices, attention!

image

Answering a question (link with more info & comparisons to OPlayer) regarding AVPlayer running on the iPhone 4 (released in Summer 2010), I've quickly tested the MKV playback in the player on my 4th-generation iPad touch (released in Autumn 2010) to find out whether the question is right. (After all, AVPlayer(HD) is probably THE most recommended generic video player, particularly for MKV playback.)



(Programmers only): WP7/8 programming for iOS developers – my quick multi-device fix for VS2012 (and an HTC 8S warning)

image

I've been porting my iOS-based Ubipix location & direction logger app (see THIS) for both Windows Phone 7(.5) and Windows Phone 8. During this, I've discovered a quick and, up to now, undocumented way of speeding up multiplatform development and to avoid having to remove / reinsert cables all the time when selecting which device to deploy the given app to.



Windows Phone programming for iOS programmers (and iOS coding tips) – Part I: Visual Studio 2012 vs. Xcode 4.x

image

With the release of Windows Phone 8 and backed by (at least when it comes to Nokia) truly excellent and unique hardware manufacturers, Microsoft's mobile platform has become really interesting. Therefore, I, a seasoned iOS programmer (and iOS programming lecturer) decided to provide you, preferably an iOS programmer (or at least a geek interested in coding) a long tutorial series specifically tailored for fellow iOS programmers to greatly help getting up to speed with Windows Phone (WP for short) programming.



Ubipix-compliant location/direction logger released (full source code + ARC migration case study)- UPDATE: saving online videos

image

In the update section of my previous article on advanced location and camera direction tagging of videos, I've already mentioned the built-in video recorder of Ubipix, currently, the only iOS application to record truly dynamic, almost (metadata is sampled every second) frame-level location and direction info, doesn't really have a decent video recorder.



The Dynamic Video Location/Direction Tagging bible (with source code)

image

Ever wanted to know whether you can know not only the precise GPS coordinates of something you've shot a video of during travel, but also the direction (based on the internal compass) of the camera while the object was taken a video of? Every wanted to know how this can be done on an iPhone (or any 3G iPad) – or, if you have a non-GPS/compass-equipped external camera, with the help of your iDevice? Read on – this article is for you!

In the first chapter of the article, I explain why you can't do this with Apple's stock Camera app – or for that matter, when compass recording is concerned, any decent(!) standalone camera out there.



iPhone 5-friendly version of video player AVPlayer -- review and tips & tricks

image

I've been asked by several of my readers to post a detailed review of, along with It's Playing and GoodPlayer, the best generic iOS media player, AVPlayer(HD).  Below, I provide you with a video / audio / subtitle / container type-dependent list of pros and cons so that you can see whether the player does fulfill your needs or not. While AVPlayer is truly an amazing player, there are some things it's entirely incapable of or where some of the alternatives are considerably better. It's based on this list that you will want to decide whether the player is for you or not, at least when it comes playing back some specific multimedia formats.

Being a video format / playback / encoding pro, I've been asked by the RockPlayer2 developers to post an honest review of their new app now that they've fixed some of the bugs and problems I've pointed out in the previous review. Here it is.
