mplayer problems with webm files

[Leonardo Taccari <iamleot%gmail.com@localhost>]

Hello,
I updated my box (i386) from NetBSD 6.0 to NetBSD 6.1 and from
pkgsrc-2012Q4 to pkgsrc-2013Q1.


After I have installed multimedia/mplayer I noticed a crash playing
webm files, so I reinstalled it with the "debug" PKG_OPTION:

 $ ftp 'http://webm.html5.org/test.webm'
 [...]
 $ mplayer test.webm 
 MPlayer 1.1-4.5.3 (C) 2000-2012 MPlayer Team

 Playing test.webm.

Here the output of gdb(1) (hope this helps):

In NetBSD 6.0 and pkgsrc-2012Q4 multimedia/mplayer worked correctly
with webm. I also did not changed my /etc/mk.conf (I will paste just
interesting lines):

 [...]
 CFLAGS+= -pipe -O2 -march=pentium-m
 [...]
 PKG_DEFAULT_OPTIONS+= -arts -esound -gnome mmx -nas -pulseaudio wide-curses
 [...]
 PKG_OPTIONS.mplayer+= -mplayer-win32 -dts -sdl debug
 [...]


Do you have the same problem? Maybe disabling the proper asm
optimizations is a possible workaround.
If you need more information or the .core file feel free to contact me!


Thank you in advance,
L.
