Video Image Processing with dynamic image size

Hello I am developing a system using Video Image Processing from Altera I need to convert a RGB 4:4:4 (24 bits) video to YCbCr 4:2:2 (20 bits) To do that, I am using the following component...

I am currently using the Video and Image processing suite version 8.0.

The only component that you need to reconfigure is the clocked video output. This can be done via the avalon interface. The clocked video input will automatically detect format changes and you can check the status via its avalon interface.

Take a look at the documentation for the clocked video output. It's pretty straightforward.

On another note. You might consider not using the clocked video input and output cores for what you are doing. The Color Space Converter is all you really need. I'd just find a way to interface to it without the other components. I'm guessing you could use the CSC core without the Video IP control packets. And of course converting from 4:4:4 to 4:2:2 is trivial.

The other cores are pretty bloated and don't really provide functionality you need.
