Werner Ruotsalainen is an iOS and Java programming lecturer who is well-versed in programming, hacking, operating systems, and programming languages. Werner tries to generate unique articles on subjects not widely discussed. Some of his articles are highly technical and are intended for other programmers and coders.

Werner also is interested in photography and videography. He is a frequent contributor to not only mobile and computing publications, but also photo and video forums. He loves swimming, skiing, going to the gym, and using his iPads. English is one of several languages he speaks.

Media Synchronization Benchmarks: FreeSync (& SyncPod) vs. CopyTrans Manager vs. iTunes – which is the fastest of all?

Many think iTunes is bloatware that should in no way be used for media synchronization. This is why I started making some very serious benchmarks. In a nutshell, the results: while the actual loading, tab switching, audio media format conversion etc. of iTunes may indeed be painfully slow, particularly under Windows, for synchronizing media to iOS devices it is in no way worse than the free and highly recommended competition. Actually, just the opposite - at least with the latest (tested) iTunes versions...

I also wanted to provide up-to-date benchmark results – something like the excellent, albeit highly outdated ones HERE.



Another quick tip: using non-AirPlay-compatible printers

image

Today, I've played a bit with printing right from iOS devices (iDevices for short).

As you may know, Apple's own solution, AirPrint, is compatible with only few printers, all from HP. (Fortunately, no longer only the [in my humble opinion] lowly and unreliable inkjets are supported, but also LaserJets, but still: there's still no support for other manufacturers' gear and not even HP's own, older models.)

Needless to say, the two printers I tried to print to, a Samsung MI-2525w and an HP LaserJet 1320, aren't supported either.



Quick tip: This is why you should and how you can transfer a whole directory structure to your iDevice

image
UPDATE (20:15 CET, the same day): a reader at MacRumors, Night Spring, has mentioned I've forgotten to point out the other and, in this case, Phone Disk-less and even Windows-friendly way of quickly transferring a complete directory structure to GoodReader running on the iDevice: zip all the files up into one big ZIP file and drop it into the File Sharing frame of GoodReader in iTunes. I've even prepared a video showing this:


Tips for editing and playing back DVB a.k.a. MPEG transport stream (TS) files and other tips

image

I've long been working on my forthcoming full(!) tutorial and comparison of everything video playback on iDevices. Now that I'm also writing a full comparison of all iDevice file accessor and media synchronizing tools, I've also very thoroughly tested the video (among other things, MPEG2 TS) conversion of the, otherwise, excellent and highly recommended SyncPod (by iSkysoft) tool. This – and the recent, great jailbreaking and XBMC releases – made me publish a separate, dedicated article. This all means that, as usual, my article contains tons of never-before-published information on generic video conversion, cutting etc. related information. Feel free to ask (in the comment section) if you'd like a more thorough explanation on any of the discussed (sub)subjects!



Other tips on programming for Cydia (or just system hacks) + new iPhone 3GS/4 video camera enhancer tools

I've played a bit more with creating Cydia packages. I've found out the following:

If you have problems installing Fink...


iOS programming: making backup copies of system files and restoring them (in the iPhone 3GS / 4 Video Camera Enhancer tools)

(Beware: highly technical article! If you aren't a programmer and/or don't want to see how my backup / restore algorithm works, step right to the last two chapters, starting with "Important note for 3G S users"!)



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



Did you know the effective resolution of the iPhone 4 video is better than that of TIPA's Best 2011 Generic P&S Camera?

image
I've made a lot of pretty advanced resolution tests today to find out the effective (real) resolution of my iPhone 4 and 3G S hacks and enhancements.

For this, I've used the well-known ISO 12233 resolution chart available HERE for printing / ordering. Please read THIS (additional info in THIS / THIS / THIS article) in order to be able to correctly understand how the frame grabs should be evaluated.


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:
