昨晚我从 13.10 升级到了 14.04。重启后，我无法在 smplayer 上播放 mp4 视频。（也无法使用终端从 mplayer 播放）我收到以下错误。
$ mplayer '/home/vishwaje/Desktop/A-ha - Take On Me Official Music video - YouTube [360p].mp4'

MPlayer interrupted by signal 11 in module: demux_open
- 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.
[ This binary of MPlayer in Debian is currently compiled with
'--enable-debug'; the debugging symbols are in the package
'mplayer-dbg'.]
所以我重新安装，并做了我能做的一切。但没有运气。请帮忙。
