A quick demo movie of my CoreVideoFunHouse (does that name sound familiar?) code.
The project shares code with my Sequence Grabber project and renders QuickTime movies using QTKit and CoreVideo. It also uses macros made up of multiple Core Image filters and defined in a simple XML file, each item in the popup menu is a [...]

Spurred on by interest in my Sequence Grabber source code I’ve added a whole slew of new functionality to it tonight (for various reasons this code is a lot of fun to work on). The most important change is CCoreImageView now supports Cocoa bindings and has an Interface Builder palette. This means you can easily [...]

My sequence grabber code (previously mentioned here) has been updated. It should be a lot easier to get up and running now - I’ve added a “CSequenceGrabberView” NSView subclasss that you just need to drag and drop into your nib’s NSWindow. I’ve also improved the error handling so that the lack of a plugged in [...]

In my previous post I talk about the (rather pitiful) attempts at adding motion capture to my Sequence Grabber code. This post will document what additions I’ve made to the code under the covers.
1) Added code to write CoreImage images (CIImage objects) to a QuickTime movie (currently hardcoded to mpeg4) using QTKit. Now you execute [...]

I’ve added basic motion detection capabilities to Cocoa Sequence Grabber code now.
This is what happens when your cat wakes you up too darn early after peeing under the computer desk.
Sample movie (MP4/QuickTime 7 required, 64KB file): MotionDetection.mp4
No those aren’t mpeg encoding artefacts, those are my attempts to highlight the motion in the movie.

Just for fun I added four seperate preview panes for my Sequence Grabber code - each pane has its own CoreImage filter attached. All previews can be flipped horizontally as well (I just apply an affine transformation to the image before handing it off to the four preview filters). I also fixed a couple of [...]

I’ve improved my Cocoa Sequence Grabber code (read: iSight code). I’ve added a couple of extra classes to represent audio and video channels. Gone are the dependencies on my MoreFile framework and some of my other Cocoa/Carbon utility classes (making the project more lightweight). I’ve improved the code all round - but the key addition [...]

Cocoa source code showing how to use a QuickTime Sequence Grabber (e.g. an iSight camera) from your Cocoa application.
Update. I’ve uploaded a new version of the SequenceGrabber source code that should compile cleanly on any Mac OS X 10.3 machine. Thanks to “jlecuyer” for pointing out the original version was broken.
Update: Information on new version [...]
