I wonder why you should have a vectorscope in real time if the point is showing histograms to humans.

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.

wait, are you saying that someone that was trained on how to use a vectorscope would not notice the image not changing frame by frame in real time? that is absolutely ludicrous. i grew up using waveforms/vectorscopes/audio phase meters, and seeing 1/5 of the data would drive me crazy. that would be like watching streaming video with buffering problems. we no longer use RealMedia for a reason

Well it's clearly some kind of strange requirement to require a relatively low power and specifically the RK3588 instead of any other chip or even Desktop chip.

It's a lot of work for some processor likely using less than 5W of power. Impressive for sure but now I'm curious what application this is for in general.

Who needs to do this but doesn't want to use a far more powerful cell phone or laptop processor?

Not to hate on the work at all! It's clearly a lot of effort to get this to run on such a relatively small chip.

Maybe it's just exercise to learn how to use OpenGL on such a small platform for GPGPU compute? Might be good reason enough to try to accomplish??

Rk3588 was originally designed with smart screens as one possible use case. That's why it has an HDMI input on board (and several video outputs).
