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.



REVIEW: New version of free(!) multimedia player RockPlayer2

image

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.

Pros



GREAT news: AVPlayer(HD) is back to the AppStore - with official AC-3 support

image

It took more than three months for AVPlayer(HD), one of the best iOS multimedia players (iPhone / iPad versions), to reenter the App Store. My previous, dedicated article (with more than 16,000 shares) is HERE. Now it's back -- and with official AC-3 support!



The Video Metadata bible & Roundup

If you have ever purchased a movie (TV show etc.) from the iTunes Store, you may already have noticed it has some additional metadata (description, staff listing etc.) nicely rendered in the desktop iTunes:

Tutorial & Roundup: This is how you can stretch your video so that it entirely fills your iPad's (iPhone's) screen

image

Over at MacRumors (thread), I've been asked to compile a list of players that can vertically stretch a video so that it entirely fills the iPad's screen. During this, it does sacrifice the right aspect ratio and does distort the image. However, at least it doesn't cut off the sides.

Here's a 16:9 movie (my well-known resolution chart video available for download HERE) not filling in the (much taller) screen vertically in the built-in stock Videos app:



Excellent media player yaPlayer becomes free - don't forget to download it!

image

yaPlayer (AppStore link), an absolutely stunning excellent video player when it comes to H.264 and MPEG-2 playback (main review; last piece of news), has just become free – along with some new features and bugfixes. Now, there is no point in NOT downloading it – after all, what can you lose? It won't cost you anything.



Don't forget: the new YouTube client supports Closed Captions at last! (+ some Java / iOS / YouTube API programming)

image

With Google's own YouTube client, the biggest problem has always been the lack of Closed Caption (CC; a.k.a. subtitle) support. It was in no way possible to display subtitles in a video, not even in the latest iOS version (still) having the client built-in. Not so with the recently-released, updated, iPad- and widescreen-friendly, free(!!) YouTube client (AppStore link), which shows a CC icon, making it possible to activate CC's, in Landscape orientation on all models and Portrait orientation on iPads:
