This does all the actual bit counting as a final step.

No speed difference. This is to allow for more flexible bit counting.

rather than in the AC3Block struct.

This will make it easier to access the bap values without having to chase
the reference block pointers each time.

Also deprecate avcodec_get_pix_fmt_name() in its favor.

This silences numerous compiler warnings from skip_bits(),
where the cache variable is not used.

Aligned local variables must use the LOCAL_ALIGNED macro to ensure
correct alignment on all systems.  The unusual size argument to
memset is required since the implementation of LOCAL_ALIGNED may
use a pointer to an array.

This adds basic stream format support and allows for arbitrary bit rates
rather than just those supported in AC-3.

use only selected options for the different AC-3 encoder types.

This function uses old-style vector operations deprecated in VFPv3.
Some implementations, e.g. Cortex-A9, support them only through
slow software emulation.  Cortex-A8 does have this functionality
in hardware, but as it also has NEON, this function is not used
there regardless.

Uninitialized coefficients were being used to generate exponents, some
of which actually ended up in the final stream.  Even though, they were
just extra exponents that are not used by any decoder, it is still
better to have consistent output for testing. This also fixes valgrind
errors.

It was long ago superseded by msmpeg4_version.

Prevent out-of-buffer writes. In particular fix smclocki32.avi.1.1
crash, trac issue #114, roundup issue #1482.

The channel_layout may have been set by the demuxer.

Fix decoding of QT WRAW files.

From some tests it results that:

1. all of the AVI/MOV WRAW files (at least from the link posted
   to the trac ticket #108) need to be flipped
2. mov WRAW files need to use AVI color modes
3. assigning PAL8 mode by default to WRAW codec is not correct

Fix decoding of file CarltonMovie2.mov, fix trac issue #108.

Since image initialization was moved after tag parsing, the
palette needs to be specified in the context and then copied
to the allocated image in init_image().

Fixes a regression with TIFF images that have palette data,
trac issue #230, file Test_Flate_8bpp.tif.

The encoder has never produced files that could be decoded
with any software and there should be no reason to create
such files anyway.

Channel coupling is an optional AC-3 feature that increases quality by
combining high frequency information from multiple channels into a
single channel. The per-channel high frequency information is sent with
less accuracy in both the frequency and time domains. This allows more
bits to be used for lower frequencies while preserving enough
information to reconstruct the high frequencies.
