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?

    Overlay isn’t transcoding. All it need is a muxer like MKVToolNix. I doubt it need much processing power.

        It doesn’t and I didn’t ever mentioned HDMI in my reply. Just doubt if overlaying another encrypted stream with a muxer ever need that much processing power to the point of “prohibitively expensive”.

          Encrypted streams also don’t have anything to do with a muxer, I really don’t understand what you’re trying to say. Muxers are for handling file formats, which is not being discussed at all, this is about raw video frame processing in hardware.
