e62a55b92e The SSSE3 version of dct_quantize in mpegvideo_mmx_template.c needs 
inv_zigzag_direct16 16-byte aligned, so mark it appropriately.
Fixes encoder crashes e.g. with MPlayer's -vf lavc.

258b60c224 Gcc idiocy fixes related to filter_mb_edge*. 
Change order of operands as gcc uses a hardcoded register per operand it seems
even for static functions
thus reducing unneeded moved (now functions try to pass the same argument in
the same spot).
Change signed int to unsigned int for array indexes as signed requires signed
extension while unsigned is free.
move the +52 up and merge it where it will end as a lea instruction, gcc always
splits the 52 out there turning the free +52 into an expensive one otherwise.
The changed code becomes a little faster.

68cf92ee5e Always call avcodec_thread_init() 
The various avcodec_thread_init() functions are updated to return
immediately after setting avctx->thread_count.  This allows -threads 0
to pass through to codecs.  It also simplifies the usage for apps
using libavcodec.

92c6a099ba H264 DXVA2 implementation 
It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
 It is implemented by using AVHWAccel API. It has been tested successfully
for some time in VLC using an nvidia card on Windows 7.

 To compile it, you need to have the system header dxva2api.h (either from
microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h)
 The generated libavcodec.dll does not depend directly on any new lib as
the necessary objects are given by the application using FFmpeg.

7c2de274e7 Add forgotten include of h264_mvpred.h to h264.h. 
This could have caused the linking failure of pred_pskip_motion() missing if
a compiler included never used static functions.

c816d3d042 AAC: Compress codebook tables and optimise sign bit handling 
The codebooks each consist of small number of values repeated in
groups of 2 or 4.  Storing the codebooks as a packed list of 2- or
4-bit indexes into a table reduces their size substantially (from 7.5k
to 1.5k), resulting in less cache pressure.

For the band types with sign bits in the bitstream, storing the number
and position of non-zero codebook values using a few bits avoids
multiple get_bits() calls and floating-point comparisons which gcc
handles miserably.

Some float/int type punning also avoids gcc brain damage.

Overall speedup 20-35% on Cortex-A8, 20% on Core i7.

not guaranteed to be fixed 4 bits per sample.
