[FFmpeg-devel] [PATCH 000/279] New channel layout API

Imagine an orchestra recording:

Orchestra, front left
Orchestra, front center
Orchestra, front right
Orchestra, low freq
Orchestra, rear left
Orchestra, rear center
Winds, left
Winds, right
Percussions, left
Percussions, right
Strings, left
Strings, right

We cannot have enums for winds, percussions and strings, but we should
be able to label them properly left and right, and attach a string label
to each.

Apply remixing matrices on channels from different parts of the
orchestra.

Let a very smart codec detect correlations, and therefore solutions for
better compression, between one section and another.
