[EMAIL PROTECTED]:~$ luvcview -L
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
/dev/video0 does not support read i/o
{ pixelformat = 'YUYV', description = 'YUV 4:2:2 (YUYV)' }
{ discrete: width = 640, height = 480 }
Time interval between frame: 1/20,
{ discrete: width = 160, height = 120 }
Time interval between frame: 1/24,
{ discrete: width = 176, height = 144 }
Time interval between frame: 1/24,
{ discrete: width = 320, height = 240 }
Time interval between frame: 1/24,
{ discrete: width = 352, height = 288 }
Time interval between frame: 1/24,
{ discrete: width = 800, height = 600 }
Time interval between frame: 1/7,
{ discrete: width = 1024, height = 768 }
Time interval between frame: 1/7,
{ discrete: width = 1280, height = 800 }
Time interval between frame: 1/7,
{ discrete: width = 1280, height = 960 }
Time interval between frame: 1/7,
{ discrete: width = 1280, height = 1024 }
Time interval between frame: 1/7,
then i tried
luvcview -f yuv -s 640x480blank
luvcview -f yuv -s 160x120
luvcview -f yuv -s 176x144blank
luvcview -f yuv -s 320x240no
luvcview -f yuv -s 352x288error 5
luvcview -f yuv -s 800x600too big
luvcview -f yuv -s 1024x768too big
luvcview -f yuv -s 1280x800too big
luvcview -f yuv -s 1280x960too big
luvcview -f yuv -s 1280x1024too big
but i had only snapshot or green screen, but no streaming.
finally i ttried this:

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

can't and
won't help unless you provide this information when reporting a
