Description

A video digitizer component converts video input into a series of digital video images. It is a low-level component which provides QuickTime with a consistent software interface used to interact with video digitizer hardware. The data supplied by the 'vdig' component can either be displayed on screen, captured, or further processed by an application.

SoftVDigX demonstrates the "Compressed Source" model and an updated implementation of the Video Digitizer APIs for Mac OS X. SoftVDigX consists of two separate projects which must be used together:

1) SoftVDigX.component - A Compressed Source Video Digitizer 'vdig' component.

2) SoftVDigXKEXT.kext - A KEXT which simulates some fictional hardware providing '2vuy' data.

HackTVCarbon or WhackedTV are good companions to this sample.

SoftVDigX will also work with Final Cut Pro 4.0.1+
