[MPlayer-cygwin] mplayer optimization for AMD x2

[Anatoli Marinov]

Hi folks,

I am an old mplayer's fan so I use it with many OSes. Currently I am
trying to build ultimately optimized mplayer for my AMD 4600+ x2
processor (for windows XP).
I found somewhere a description how to build it step by step with
mingw. The manual was a pretty old but however now I have proper
environment with latest ming stuff. Yesterday I have compiled current
mplayer sources from SVN repository and everithing works fine but I am
curious about several thing:

1.  I've compiled (configured) my mplayer without runtime CPU
detection and with these flags:
  --enable-mmx              enable MMX [autodetect]
  --enable-mmxext           enable MMX2 (Pentium III, Athlon) [autodetect]
  --enable-3dnow            enable 3DNow! [autodetect]
  --enable-3dnowext         enable extended 3DNow! [autodetect]
  --enable-sse              enable SSE [autodetect]
  --enable-sse2             enable SSE2 [autodetect]
  --enable-ssse3            enable SSSE3 [autodetect]

The CPU supports all these sets of instruction. Does ssse3 work
because I didn't see nothing special with or without it?
When I start the player with x264 encodec file I see:
$ ./mplayer.exe /1.mkv

see this line ->  CPUflags:  MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 0 SSE2: 0
This compilation supports sse, sse2 and sse3 but why the flags are 0
and sse3 missing?
and this too- > Compiled for x86 CPU with extensions: MMX MMX2 3DNow
3DNowEx SSE SSE2 - missing sse3 why ?

2. For h264 decoding I am using default x264 functionality from ffmpeg
internal codec bundle. Is it better than x264 library from
videolan.org?

3. Can I compile fully statically linked mplayer binary and how?

4. Could you tell me more hints for better performance :) especially
for h264? Is it possible to use hardware acceleration mechanism from
my nv8600GT video card because it has hardware h264 decoder, filter
etc.

5. What about pthreads support. I couldn't find pthreds for mingw.
Will it works faster with pthreads or not?

Lol I have so many questions :P
