[vlc-devel] [PATCH 0/3] Support third order ambisonic

[Pierre Lamot]

Opus only support family 2 channel mapping as described in RFC
draft-ietf-codec-ambisonics-04. Current opus implementation can use family 254
as a temporary (?) mapping.

current mixing of non-diegetic channels is quite naive and might taint spatialisation,
Not sure whether we should normalise the other channels (front/rear/sub)

Pierre Lamot (3):
  spacialaudio: discard non diegetic channels
  spacialaudio: mix non-diegetic streams on left/right speakers
  opus: support third order ambisonic with family 2 mapping
