I did describe what has to be done to properly support ambisonics as to
make this patch work properly. I know it works for Google's usecase but I'm
against "by-chance" ambisonics where you rely on a specific channel layout
and a specific encoder encoding them with a specific setting.
We still have bits leftover for channel layout and I'd agree to add an
extra bit to indicate the particular layout carries ambisonics, with the
number of channels indicating the order. This wouldn't need extensive
channel layout API replacements and would still be sufficient to implement
both encoding and decoding of such audio.
