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.
  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.
