This enables UAL syntax for all asm files instead of only those
which happen to be incompatible with the old, deprecated syntax.

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

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

This will make it easier to access the bap values without having to chase

This silences numerous compiler warnings from skip_bits(),

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.

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().
