I will try this on a later build, but would prefer to use a stable build.
To date I have been working with FFMPEG 2.0

option, don't you agree?
I would agree yes, however I cannot get to compile/get to the linking
stage without this. Possibly an Oracle Compiler issue, I am unsure but
the original article I used to help do an initial compile has stuck:
http://chrismiles.livejournal.com/25439.html
If i exclude --disable-mmx, I get the compilation issue:
CC libavfilter/vf_mergeplanes.o
CC libavfilter/vf_noise.o
"vf_noise.c", [line_noise_avg_mmx]:ube: error: Cannot allocate register
for argument '%5' in GASM Inlining
cc: ube failed for libavfilter/vf_noise.c
gmake: *** [libavfilter/vf_noise.o] Error 2
> Are {{{--cc}}} and {{{-cxx}}} necessary? Why?
So it doesn't pick up gcc to build with. We don't build with gcc, we
build with the Oracle Compiler.

Original problem is that building a C++ program using the static libs puts
a dependency on the CPU requiring the AMD 3d Now instruction set, which is
unsupported. Linking with the dynamic libs instead of the static libs
does not result in the dependency or seem to have any issues, so it could
and is very likely it is a problem with the CC compiler, or I am missing
some sort of flag on the compiler to exclude instructions that are not
supported by the CPU, if such a flag exists.
