This is the remaining error, the output on the SPX samples,
respectively csi_miami_stereo_128_spx.eac3 and
csi_miami_5.1_256_spx.eac3, goes from:
stddev: 8.71 PSNR: 77.52 MAXDIFF: 235
stddev:24270.51 PSNR: 22.17 MAXDIFF:47166
to:

When the decoder is deactivated, the x86-optimized versions are
not compiled, resulting in a link error.
The C version is unaffected, as it is part of the idctdsp
subsystem.

The AC3DecodeContext has a float (USE_FIXED=0) and an integer
(USE_FIXED=1) variant, both of which can be present in the same binary.
This is not only very confusing, but it also breaks horribly, when one
variant is used by code expecting the other.
This currently happens, because eac3dec.c is only compiled for the float
variant, but also used from ac3dec_fixed.c, which uses the integer
variant.
The result is memory corruption, leading to crashes.
So compile eac3dec.c once for each variant and adapt it, so that it
works with the integer variant.
A loss of precission and scaling bug has been fixed by the committer

No global variables are used and the VLC tables are allocated without
static elements. This will allow using a JPEG decoding context within
other decoders.
This field is designed for marking codec properties useful to lavc internals.
Two internal capabilities are added:
- FF_CODEC_CAP_INIT_THREADSAFE: codec can be opened without locks;
- FF_CODEC_CAP_INIT_CLEANUP: codec frees memory if initialization fails.
Instead check for all mov code-points when demuxing avi
and print a warning if a video codec is found like this.
Fixes a regression similar to the one described in ticket #4307.
The main difference consists in renaming properly labels, and
letting yasm select the gprs for skipping 1D transforms.

Unfortunately android < api 21 (lollipop) doesn't have the sgidefs.h header,
the easiest way around this is to just use the preprocessor definitions from
gcc / clang.
