Following on from my previous post covering decoding and rendering HDMI input on the RK3588, I encountered a new requirement: implementing a real-time vectorscope to visualize chrominance information from the video stream. This proved to be a challenging task due to the need for efficient frame processing and rendering without impacting video playback performance.Extracting UV Data from Video Frames The challenges to overcome were:Accessing U and V (chrominance) values for every pixel in the vid...
