I have it in mind at a lower priority. To be honest, my main impetus is for better discoverability on the App Store from an iPad device. They really like to hide those iPhone apps! ;-) It will be nice to play with the interactive living ph

That's really cool, Marat. Thanks for the additional info on the A15 and Swift. It's a lot of work to optimize the assembly code to each ARM variant, but glad to know that Swift will generally run the same code at the same or fas

That's unfortunate. I suspect there's a JS memory leak in the viewer, as it will cause a crash on iOS Safari after prolonged use. It's on the list. Thanks for letting me know!

Thanks! :-) I first tried using the GPU, using old school GPGPU textures and OpenGL ES 2.0 shaders, but unfortunately the performance wasn't there for a variety of reasons given in [1]. SnappyCam has since been making extensive use of

LOL! Thanks @danpat. :-) How are you going these days? I heard you might be moving to the Big Apple?

Thanks for reporting it in! It seems I enthusiastically chose a larger buffer size that appears to be having some issues on some devices that have a lot of memory pressure. If you reboot your phone, as awful as that sounds, it will likely f

Glad to hear it. I feel the same on the format: it's closer to a photo on the left of the spectrum between photo and video, where vine/instagram/cinemagram are on the far right. You've put it very nicely--there's d

I understand where you're coming from; social proof removes a massive barrier to conversion, even in my own experience. I found that having it at $1.99 most definitely improved sales after it had been at $0.99 for about a week; after a

Oh wow, that sounds really cool! :D Will definitely look you up when I'm down next. Trying to drop by more consistently during the summer these days. I spent five weeks in Melbourne last Jan and loved every minute of warmth. :)

Yes, more RAM definitely helps. On SnappyCam, I had to arbitrarily limit the size of the buffer to a fraction of the system memory because there's no way to know "how much" RAM can be allocated to avoid the dreaded memory war

That's a cool feature, and not easy to implement. It generally ends up being a machine vision problem. (Google has both great talent and a lot more resource than a single-founder self-funded engineer like me.)

Size and quality. We've touched on it in a few other threads here if you'd like some further background.

Ouch. Looks like some work for me ahead. The problem with Chrome 28.0.1500.x (.95 here) is troubling me. It seems a more recent problem that I'm convinced is another browser bug. Thanks for the detailed version report, that's real

I'm really glad to read this! :-) I had similar thoughts myself, and forms a part of what I have in mind for the next major SnappyCam release (a taste is what you see on SnappyCam.com today). My thoughts are perhaps more web-focussed

It all comes down to what the hardware supports, ultimately. I'm not performing any true miracles here: I'm just making best use of the hardware resources available, with some clever software tricks and algorithms. The iPhone 5 ac

Versions 1.x.x of SnappyCam had a linear buffer [1] but I felt it was distracting. I generally can see the "end" of the circular buffer around the shutter button, so it doesn't seem to be an issue for me. Perhaps I tend to t

Hey Andrew, would love to catch up over a beer. :-) Drop me a note via email: jpap {at} snappylabs.com You've got a good eye: as part of the JPEG image compress, I also generate a low-resolution thumbnail that's embedded into eac

It's a webservice I hacked together that sends iMessages from my old MacBook Pro. :-) It was my understanding that German mobile numbers are written locally starting with 01? [1] e.g. in Australia, my mobile number would be 040x-xxx-xx

Weird. Could be a bug in the dropdown component I wrote in AngularJS. :( Glad the keyboard still works. Will look into it...

Practice. A lot. A good start is actually the ARM processor; since it's a RISC instruction set, it's quite simple. I've done lots of assembly in my ugrad days, even writing a Motorola HC11 micro-controller emulator, but ARM w

It's now on the list. Had a few requests for it, and agreed, it'd be cool. :)

Cheers mate, I'm from Melbourne and might just take you up on that! (I live here in SFO at the moment, but try to get back as much as I can.)

Yes, that does require some explanation: 1. The receding circle is the capture buffer being processed. When you're tapping on the thumbnail, SnappyCam sees the start of the living photo being available and shows it. It does not, unfo

I'm Aussie, so I did my schooling in Melbourne, Australia. I don't recommend the same path for everyone, but my ugrad at RMIT University, dual bachelors of EE and CS. I then went on to do a Ph.D at the University of Melbourne in

It may not be possible, even for Apple. If you have a look at the data sheets, for example [1], you'll see YCbCr or RGB output formats being listed. I guess it would make sense for as much signal processing to be done as early in the c

Thanks for the suggestions: 1. Looks like a race condition for the settings button tap. Does it happen if you wait a second before pressing the settings button? 2. You can re-enable the tutorial (overlay) screens from the bottom of the set

There's still much innovation left in image signal processing... and fortunately much interest in taking good photos! This reminds me of research into superresolution, an area that's "super interesting" :-) as well. The

Thanks!! :D Would love to see some real world comparison examples. Drop me a line when you've got something, would love to check it out. :)
