Forum Members,
I am attempting to forward a webcam output over SSH from a ubuntu server to a MacBook running OS X. I would like to open mplayer on the Mac.

Using the following code in the mac terminal:
ssh -C -X me@myip konsole
opens a konsole terminal from which I am able to open GUI programs, including kopete, and test the webcam and video forwarding. The video forwarding appears to be working fine for my purposes.

When I attempt to open the webcam using mplayer on the client side (Mac):
mplayer tv:// -tv driver=v4l:width=352:height=288:device=/dev/video0
I get the following output:
Xlib:  extension "XFree86-VidModeExtension" missing on display "localhost:10.0".
xscreensaver_disable: Could not find XScreenSaver window.
[VO_XV] It seems there is no Xvideo support for your video card available.
[VO_XV] Run 'xvinfo' to verify its Xv support and read
[VO_XV] DOCS/HTML/en/video.html#xv!
[VO_XV] See 'mplayer -vo help' for other (non-xv) video out drivers.
[VO_XV] Try -vo x11.
Error opening/initializing the selected video_out (-vo) device.

MPlayer interrupted by signal 11 in module: free_demuxer
- 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.
If I run the same command on the server (linux machine) directly, the output looks like this (and mplayer opens and displays the webcam well)
mplayer opens and the command line output is:
Opening video decoder: [raw] RAW Uncompressed Video
VDec: vo config request - 352 x 288 (preferred colorspace: Planar YV12)
VDec: using Planar YV12 as output csp (no 0)
Movie-Aspect is undefined - no prescaling applied.
VO: [xv] 352x288 => 352x288 Planar YV12
Selected video codec: [rawyv12] vfm: raw (RAW YV12)
Audio: no sound
Starting playback...
I have tried the -vo X11 suggestion in the error output. Also, xvinfo returns:
X-Video Extension version 2.2
screen #0
 no adaptors present
There are related threads looking at SSH forwarding and mplayer:
From suggestions in these threads, I have tried:
export DISPLAY=:0
mplayer tv:// -tv driver=v4l:width=352:height=288:device=/dev/video0
but this seems to open an mplayer on the server side (linux machine).

I suspect the -X forwarding is the way to go and I need to set the -display options correctly. The man page is cryptic:
-display <name>
    Specify the hostname and display number of the X server you want to display on.


-display xtest.localdomain:0
The command (on the client side running Mac)

Any suggestions would be helpful.
