[FFmpeg-devel] [PATCH 5/6] aaccoder: Move the quantization function to a separate file

Wed Jul 29 06:44:28 CEST 2015
This commit moves the quantization function to a separate file.
This is done because the current extensions under development have
separate files, and due to the fact that there was no way to get the
distortion measurements from outside the aaccoder.c file a separate
file had to be made. Most of the functions already had 'inline'
as a property which made it easy to just move them to a separate
file and include it when needed.
No functionality has been changed with the exception of the removal
of quantize_and_encode_band() from the list of function pointers.
This was only used once inside aacenc.c and did not return distortion
information, making it useless for any calculations done outside
aaccoder.c. Also, because the quantizer function is identical for all
coders and all coders use it it made no sense to keep the function
pointer, therefore it was removed.
