can i generate histogram from a video in MIT? and work with those histograms?
Do you mean a graphic display of video signal levels and isolate individual audio levels or something else?
You want is a FFT (Fast Fourier Transform) of the signal levels. Some call this a ‘histogram’ App Inventor 2 does not have that capability natively.
You might be able to use a javascript to provide that functionality … here is an example javascript FFT Click on the image to see the display example.
Otherwise you might choose to code your app using the now free B4A Android coding compiler B4A is now free! (gratis). Build app for Android and iOS in text mode and these libraries
