[MPlayer-users] Canopus decoding crash

[Horacio Sanson]

I am trying to decode some legacy Canopus HQ files I have usign MPLayer.
The list of supported codecs seems to indicate that both Canopus HQ and
Canopus Lossless are supported.

I installed the Canopus driver from http://www.thomson-canopus.jp/download/codec_option_pb.htm
in my WinXP 32bit machine and copied the corresponding dll files to my
linux (Kubuntu 9.10) /usr/lib/win32 directory.

Here is the output I get:

  MPlayer SVN-r30501-4.4.1 (C) 2000-2010 MPlayer Team

   - 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.  It can be a bug in the
     MPlayer code _or_ in your drivers _or_ in your gcc version. If you
     think it's MPlayer's fault, please read
     DOCS/HTML/en/bugreports.html and follow the instructions there. We
     can't and won't help unless you provide this information when
     reporting a possible bug.

Here is the backtrace:
