HDMI stream live processing? (lemmy.ca)

I’m getting tired of the extremely loud ads on that don’t seem to be subject to the old TV broadcasting laws that prevent them from being blasted 10db louder than the actual content. Wondering if there’s stuff out there that would let me take the hdmi stream from my Apple TV or other streaming source, and do ad detection like the olden days so that it could just mute or do volume leveling at least.

I suppose something very basic might just be an hdmi splitter to a rpi with hdmi that’ll detect ads via the black screens or “this ad will over over in 30s” overlays, then send a mute signal over CEC or something to a receiver or TV….but would be nice if it could modify the hdmi signal directly.

Thoughts on what to search for to do something like this?

in order to be able to modify the stream in real-time and send it back out...

It doesn't need to modify. What it needs is detection, and then either blacking it out, or replacing with a simple progesssbar-like screen on a black background.

I consider "blacking it out" and "replacing" to be equivalent to "modify" in this case as you still need basically the same amount of processing power to do any of it.
