Extract pixel data from video stream

Thanks for that. I'll check it out.

From vgs's helpful posts, I was thinking of implementing a new component in SOPC with a Avalon-ST sink to feed into a deep FIFO. The framebuffer can feed into this custom component and the FIFO-full output can control the READY signal. I can then retrieve the data at my own pace from the FIFO into my external device.

Of course I don't know how difficult this is but it seems to provide the necessary logic.
