Maybe I was a bit too enthusiastic; the Firefox extension I mentionned should work just fine (no need to code a new one). It has preferences to configure the player and its options; so the player could be the script that Jörn explained.
I also found a more sophisticated solution for Linux and Chrome (that should also work on OSX) https://github.com/agiz/youtube-mpv A contextual menu is added, to play the current youtube page or youtube links. This is the solution I will adopt because its javascript extension is simpler and the its server backend is in python. -- Marc On Fri, 13 Oct 2017 14:22:21 -0400 Marc Lavallée <m...@hacklava.net> wrote: > A better Firefox(and Chrome) extension should be made to detect > ambisonics content, with editable options like you suggest.
