c740f737e9 vorbisdec: Use int instead of uint16_fast_t for index variables 
uint16_fast_t is unsigned int (or long) on Linux, which when compared
with int results in an unsigned compare.

62147469da acenc: LAME-inspired window decision 
This performs quite a bit better than the current 3GPP-inspired window decision
on all the samples I have tested. On the castanets.wav sample it performs very
similar to iTunes window selection, and seems to perform better than Nero.
On fatboy.wav, it seems to perform at least as good as iTunes, if not better.
Nero performs horribly on this sample.

2a86d4b905 The 24-bit ydt also should not depend on endianness, 
since all of it ends up in a single 32-bit pixel.
This seems likely to be wrong though, since it is different
from the 15 and 16 bit modes and might explain the half-width
issue for 24 bit truemotion.

8bdf11815c Fixed mpeg12 top field first flag value with field picture encoding. 
The relevent extract of the iso 13818-2 about the value of the syntaxical
element top_field_first of the Picture Coding Extension is:

"top_field_first -- The meaning of this element depends upon picture_structure,
progressive_sequence and repeat_first_field.
[...]
In a field picture top_field_first shall have the value '0', and the only field
output by the decoding process is the decoded field picture."

A lot of the time the DC block is empty: don't do the WHT in this case.
A lot of the rest of the time, there's only one coefficient: make a special
DC-only transform for that case.
When the block is empty, don't incorrectly mark luma DCT blocks as having DC
coefficients.

6341838f3c Use word-writing instead of dword-writing (with two cached but otherwise 
unchanged bytes) in the horizontal simple loopfilter. This makes the filter
quite a bit faster in itself (~30 cycles less on Core1), probably mostly
because we don't need a complex 4x4 transpose, but only a simple byte
interleave. Also allows using pextrw on SSE4, which speeds up even more
(e.g. 25% faster on Core i7).

bcd4aa6498 Use nested ifs instead of &&, which appears to not work with %ifidn (i.e. this 
construct was always enabled, even for <ssse3 versions).

2208053bd3 Split pextrw macro-spaghetti into several opt-specific macros, this will make 
future new optimizations (imagine a sse5) much easier. Also fix a bug where
we used the direction (%2) rather than optimization (%1) to enable this, which
means it wasn't ever actually used...

e3f7bf774c Fix SPLATB_REG mess. Used to be a if/elseif/elseif/elseif spaghetti, so this 
splits it into small optimization-specific macros which are selected for each
DSP function. The advantage of this approach is that the sse4 functions now
use the ssse3 codepath also without needing an explicit sse4 codepath.

3611e7a309 Inline asm for VP56 arith coder 
This is a lot more reliable to get cmov rather than trying to trick gcc into
generating it, useful since it's 2% faster overall.

fe1b5d974a Decode DCT tokens by branching to a different code path for each branch

Based on the similar optimization in libvpx's detokenize.c
