Can you point me to that chromecast tool or tell how it worked?

I'm in the process of releasing a video player with adblocker for live IPTV on android that can definitely auto-mute the whole adbreak for you if you watch the stream in the player (see my previous comment for link).

But if you are suggesting a system-wide mute triggered by a dormant app as another live broadcast plays in some official app then that's easier in some respects and harder in others because people need to trust the data is accurate. Once we have enough users sharing accurate adbreak data (powered by accurate software with human corrections) we can offer a system-wide mute for ads in any other app playing those known broadcasts.
