Simple and available video decoders?

Hi,

I want to develop my own video grabber, for some experimentation with video
image processing. I wonder if there is a preferred video decoder often used
in hobbist like projects?

I looked up some available analog video decoders, like the Texas Instruments
TVP5150A, which seems quite easy to use. However they all seem to output
only YCrCb, the TVP5150 no different outputting 8-bit ITU-R B.656. I need a
chip that can also output raw RGB, since I assume that is what I need in my
VRAM bank for simple edge detection and object tracking capabilities.

Any suggestions appreciated.
