MPlayer (liba52) crash on Vista 32-bit (CPU T5600) Compiled with MinGW GCC 4.2.1-dw2

Description

Both the latest svn and 1.0rc2 crash.

My System is Vista Home Basic 32-bit Edition, Core 2 T5600

Compiled with MinGW GCC 4.2.1-dw2

when playing a file with ac3 audio it crashes.

But ffac3 can play the audio properly (but it seems -ao pcm fails)

so maybe there is something wrong with liba52. Should I try to replace the
routine imdct_512_do_sse with the no-optimization Version ? ...

When I delete imdct_do_512_sse and

#define imdct_do_512_sse imdct_do_512

It works fine.

Some thing wrong with the asm code? or the Compiler? or the CPU....

comment:2 Changed 11 years ago by compn

--disable-sse might also work
it was disabled on mingw for a long time because of some crashes

not sure what current status is

comment:3 Changed 11 years ago by liuxiaogenius@…

(In reply to comment #2)

--disable-sse might also work
it was disabled on mingw for a long time because of some crashes

not sure what current status is

Thank you for reply

--disable-sse will disable other sse optimization...So I prefer Delete the function in imdct.c (Haha, the advantage of open source)

I just use ./configure to configure, It doesn't disable sse...

All right. Then I know it has no cure now.

I dont know if it's the same problem here or a new bug. When I try to play a MPEG2-PS file with ac3 sound MPlayer crashes. Maybe the attached core dump can help. I'm using Ubuntu Hardy and gcc 4.2.3.

comment:6 Changed 11 years ago by mplayer@…

  • Cc mplayer@… added

I've already explained my test results on the ml.

I had same problem in my builds

using binutils 2.18 + mingw runtime compiled using bu 2.18:

  • attribute aligned 16 does not always work (in this case you'll get a crash)
  • attribute aligned > 16 just forget the idea

using binutils 2.17 + mingw runtime compiled with bu 2.17:

  • attribute aligned 16 always work
  • attribute aligned > 16 just forget the idea

So if you are using new binutils downgrade to 2.17
mingw runtime from mingw looks ok

you may try my Full Build environment:
http://sourceforge.net/project/downloading.php?groupname=mplayer-win32&filename=MinGW-full-gcc-4.2.3.7z

mplayer p4 builds: liba52 ok, x264 ok, xvid ok

imho the bug cannot be fixed "mplayer side"

Regards
