/**
|
||||
* List of PCE (Program Configuration Element) for the channel layouts listed
|
||||
* in channel_layout.h
|
||||
*
|
||||
* For those wishing in the future to add other layouts:
|
||||
*
|
||||
* - num_ele: number of elements in each group of front, side, back, lfe channels
|
||||
* (an element is of type SCE (single channel), CPE (channel pair) for
|
||||
* the first 3 groups; and is LFE for LFE group).
|
||||
*
|
||||
* - pairing: 0 for an SCE element or 1 for a CPE; does not apply to LFE group
|
||||
*
|
||||
* - index: there are three independent indices for SCE, CPE and LFE;
|
||||
* they are incremented irrespective of the group to which the element belongs;
|
||||
* they are not reset when going from one group to another
|
||||
*
|
||||
* Example: for 7.0 channel layout,
|
||||
* .pairing = { { 1, 0 }, { 1 }, { 1 }, }, (3 CPE and 1 SCE in front group)
|
||||
* .index = { { 0, 0 }, { 1 }, { 2 }, },
|
||||
* (index is 0 for the single SCE but goes from 0 to 2 for the CPEs)
|
||||
*
|
||||
* The index order impacts the channel ordering. But is otherwise arbitrary
|
||||
* (the sequence could have been 2, 0, 1 instead of 0, 1, 2).
|
||||
*
|
||||
* Spec allows for discontinuous indices, e.g. if one has a total of two SCE,
|
||||
* SCE.0 SCE.15 is OK per spec; BUT it won't be decoded by our AAC decoder
|
||||
* which at this time requires that indices fully cover some range starting
|
||||
* from 0 (SCE.1 SCE.0 is OK but not SCE.0 SCE.15).
|
||||
*
|
||||
* - config_map: total number of elements and their types. Beware, the way the
|
||||
* types are ordered impacts the final channel ordering.
|
||||
*
|
||||
* - reorder_map: reorders the channels.
