Most of the code in mplayer should be "byte-order" clean, now.  And it
doesn't access unaligned int16/int32 values any more on non-x86 cpus.
The code compiles and mostly works on SPARC Solaris 2.6 or newer (there
some issues with Solaris 2.5.1, missing inttypes.h, no snprintf,
etc...).   One remaining issue I know is with some mpeg1 videos, where
sound output doesn't work (mp3/mp3lib, produces noise,  only on a
big-endian/SPARC machine).

The code currently compiles (and benchmarks :-) without problems on
sourceforge's compilefarm on the Linux/RS/6000 PowerPC machine and the
Linux Ultra60 SPARC machine.  I don't know what it looks and sounds
like, if you sit in front of a real Linux/PowerPC or Linux/SPARC
machine using mplayer, though  ;-)


The code also compiles on the Linux/alpha compilefarm box, but
immediatelly crashes when you run it with an .avi file.  So,  mplayer
is probably not 100% 64-bit clean, yet.



Problem is of cause that some DivX movies use 0x160/0x161 audio format 
(DivX audio WMA), and that's not available on non-x86 platforms, because
the only audio codec currently uses the win32 DLLs.


Porting the code to IRIX shouldn't be too difficult...
