I wonder why you should have a vectorscope in real time if the point is showing histograms to humans.<p>As the image does not change much frame to frame, I presume that if you compute it and display it every fifth frame or so, nobody would ever notice.
The previous post about using the RK3588 as an hdmi analyzer is a nice read! I am looking into the Orange Pi 5 Plus as a stream media device, that would output videa and audio streams seperately on each of its 2 hdmi out port, but now give that it supports HDMI input, I wonder if it's possible to make it act as a "Audio Extractor" by taking my gaming console PC feed and splitting it into 2.
