doc/encoders.texi: update documentation for the native AAC encoder · e34e3619

Rostislav Pehlivanov authored Dec 05, 2015

Since the next commit removes the experimental flag from the encoder
it's better to update the documentation which has been around in its
current form for as long as the encoder itself.

aacenc: mark coders other than twoloop as experimental · b270ec9a

ANMR has some interesting things coming up but is currently not in a
shape fit for non-experimental usage. Same with "FAST".

aacenc: mark the "faac"-like coder for removal · 3a6e0208

Rostislav Pehlivanov authored Dec 05, 2015

This coder produces a much lower quality audio than the rest, is much
slower and is unstable. Hasn't been updated for a very long time as
well, hence it is more appropriate to remove it since it also depends on
a big burden of a code (the encode_window_bands_info function which is
just as old, just as unstable and bad and in no way modifiable or
fixable).

Vicente Olivert Riera authored Dec 03, 2015

Having a configure option with the same name as a MIPS ISA is confusing,
so better to remove it. This option was being used to add some
optimizations to a specific core (p5600). We will add the optimizations
just when the p5600 core has been detected, in a later patch.
