This fonction will compute the extraction parameter into pi_selection to go from i_channels with their type given by pi_order_src[] into the order describe by pi_order_dst.

It will also set :

  • *pi_channels as the number of channels that will be extracted which is lower (in case of non understood channels type) or equal to i_channels.
  • the layout of the channels (*pi_layout).

It will return true if channel extraction is really needed, in which case aout_ChannelExtract must be used

XXX It must be used when the source may have channel type not understood by VLC. In this case the channel type pi_order_src[] must be set to 0. XXX It must also be used if multiple channels have the same type.

This function computes the reordering needed to go from pi_chan_order_in to pi_chan_order_out.

If pi_chan_order_in or pi_chan_order_out is NULL, it will assume that vlc internal (WG4) order is requested.
