...I am not doing anything special with the MID channel samples".
libFLAC will always give you the L/R channels to your read callback.
for M/S frames, it will convert the samples to L/R before calling
the write callback.
also, INDEPENDENT frames are just frames that are coded L/R, as
opposed to MID_SIDE frames which are M/S. both kinds can have LPC
subframes. (see also http://flac.sourceforge.net/format.html).
but none of this should be noticed by the client because libFLAC
in the end converts everything to uncompressed L/R samples and
passes those to the write callback.
INDEPENDENT frames can...

Please help me understand what values of FFMPEG's "compression_level" preset generate subset FLAC stream and what not-subset?
...E...A...
-ch_mode <int> E...A... Stereo decorrelation mode
(from -1 to 3) (default -1)
auto E...A...
indep E...A...
left_side E...A...
right_side E...A...
mid_side E...A...
Presets for each compression_level:
[flac @ 000000000034ff60] compression: 0
[flac @ 000000000034ff60] lpc type: Fixed pre-defined coefficients
