[MPlayer-users] Using with webcam Genius Look 320s

[Stanislav_Egorov]

Hello,

I've tested mplayer with my cam in raw mode of the format(switch on it
in the driver) and now I see the follow:

mplayer tv:// -tv

x11
mplayer: Symbol `rgb32to24' has different size in shared object,

MPlayer interrupted by signal 11 in module: filter_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.

Can you comment this? When it happens I see the contours of the
mplayer window, but it freeze.
