Is it possible to change an audio stream or video stream on the fly?

Question

Lets see people tap a button at any point in the audio or video stream and I want to show dynamically change the stream depending on how many people tap on it. Would FFmpeg be the best way of doing it?

Depends on the change you want yes, you can apply filters on chunks https://ffmpeg.org/ffmpeg-filters.html
