[Ffmpeg-devel] [PATCH] split up AC-3 bit allocation

[Justin Ruggles]

Hi,

This is a patch to separate the bit allocation in AC-3 into 3 parts.
This will enable increasing the speed of both the encoder and future
decoder.  Essentially, each part of the bit allocation is only necessary
if certain conditions have changed since the last block.  This will be
especially useful in the encoder, where many of the bit allocation
parameters are kept constant for simplicity.

The old ac3_parametric_bit_allocation() function will eventually be
removed once the encoder is adapted to use the separate functions instead.
