[MPlayer-users] xvidix and x86-64 problems

[gwondaleya at free.fr]

Hello,

I have an athlon64 3000+, Mandrake linux 10.0 installed, ATI radeon 9200 Pro 128
M, 64 bit (but powertweak is sayin 32bit wide....), motherboard ASUS K8V-X (via
k8t800)

First of all, using pre compiled binaries or cvs (idem with others players too)
to  play a DVD, it eat a lot of CPU (more than 50%...) (xv driver), but it is
not the problem here (well , almost, since such a CPU must be able to cope with
a DVD without eating so MUCH power, since i used to play dvd correctly on my
athlon 1200, not XP and a Sis6326 card)... Don't know really why, i have to
check this deeply, but if you have a clue.....

But nevertheless, when i use to run precompiled mplayer(MPlayer 1.0pre5-3.4.1
(C) 2000-2004 MPlayer Team from Mandrake package) (i assume it is a 32 bit
version, since i am able to use windows dlls) with the vo xvidix driver, then i
have less than 50% CPU and i am also able to play HD content from divx.com (for
example Madagascar) without eating all the cpu power, which is nice.

When i try to use my own compiled version (CVS, affect all the versions i have
tested so far) i have problems of segfault using the xvidix driver. The
segfault occurs at the very first frames displaying:

 ./mplayer -vo xvidix -dr -nortc -cache 32000 /videos/Madagascar.mkv

MPlayer interrupted by signal 11 in module: decode_video
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.


using gdb it gives:
