Versatile content / media loader:

ActionScript 3 introduced new ways to load content and new types of content – now Flash can handle raw bytedata. This also increased the complexity of the process. You need a Loader, URLLoader, URLRequest, event listeners…

ContentLoader is a class that simplifies the process into a one class that can fulfill most of the basic needs:

– send and load data

– load bytedata

– load variables

– hande errors

– load images, mp3s, xml, text (JSON too, of course, but parsing is not supported)

Loading and handling external files in Flash:

Here’s another helper class that loads one or multiple file(s) separately or all in a batch. There is one special feature: this class can check the filesize of each file (without fully loading them) and therefore it can show the loading progress of the whole batch not just single file. The loaded data is stored so the file or its size is never loaded twice.

This class uses my ContentLoader as the actual file loader. Read more about the ContentLoader »

Ignoring black frames while starting a webcam

While playing with motion detection with a Webcam, I ran into a surprising problem. First n frames are 100% black. The number of frames vary, so this problem wasn’t solved with ignoring first 10 frames or anything similar. So I used getColorBoundsRect to detect any non-black pixels and when found, the WebCam class would start to send an event. The video will be visible before dispatching events, but it could be hidden until the event is dispatched. Jatka lukemista ”Ignoring black frames while starting a webcam”
