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.

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.

Hello, Jake!

Did You use Color Space Converter and Chroma Resampler without CVI and CVO in Your own practice?

In my case the 422 YUV 20-bit stream is coming to Chroma Resampler + Color Space Converter not from outside FPGA ( in which case CVI is used in front of all ), but originates within FPGA.

Same thing with output - the RGB 30-bit stream coming from Chroma Resampler + Color Space Converter is not directed to outside FPGA ( in which case CVO is used ) , but stays within FPGA for further processing.
