This also allows to remove a linking dependency of libavfilter on
libavcodec.

that flag to the dca codec. This capability when set
will make sure the codec will initialize the channel
configuration instead of trusting the container. This
fixes issue 2137 and issue 850.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

This reorders the lfe_fir tables, and drops the mirrored half,
such that the loops in lfe_interpolation_fir() can be simplified.
The new loop structure should be easier to implement with SIMD.
Static data size is reduced by 2kB.
3% faster on Cortex-A8.

This prevents gcc reloading the value from memory on each iteration
of the loop.

Optimised implementations of the synth filter will require these
arrays 16-byte aligned.

These macros are redundant. All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

It happens when the number of channels defined by DCAContext:acmod is lower
than DCAContext:prim_channels. In this case, dca_subsubframe() will call
qmf_32_subbands() using s->channel_order_tab[] entries equal to -1.

Scaling (i)MDCT output has no runtime overhead and can be used to improve
performance of audio codecs. All the changes are only needed in
'ff_mdct_init' function and slow down initialization a bit.

AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.
