It would be called while registering the codec, which means
it needlessly wastes memory when it is never used.
Instead do the work when first opening the codec.

Other parts of FFmpeg use NE (native endian) rather than ME (machine).
This makes it consistent.

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.

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

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.
