Why do I see the following error when generating the Video Mutli-Scaler example design on Windows?
This is a known issue with the Vivado HLS compiler on Windows (the Video Multi-Scaler is an HLS-based IP).
When synthesizing designs that contain HLS Based IP such as the TPG or VPSS, always reduce the path as much as possible.
Make the project name as short as possible, and place it in the shortest possible path (C:\x).
For more information on the path length issue, see (Xilinx Answer 52787).
