What steps will reproduce the problem?
1. v4lstereo is fantastic in embedded applications, but
has no way to transfer the data back to a controlling machine.
What version of the product are you using? On what operating system?
Latest SVN (r64) on Ubuntu Karmic i386 and armel (on BeagleBoard)

Please provide any additional information below.
The following patch should add streaming support to v4lstereo r64. It adds
a build dependencies:
libgstreamer-plugins-base0.10-dev
libgst-dev
Please be gentle, this is my first real work with C++ and so I couldn't
figure out how to selectively disable stuff at build time. I just modified
the makefile to add the required support flags. The patch does not add
much overhead to program, but could probably be done in a more efficient
way.
The streams are raw jpegs over a tcp socket - the gstreamer pipeline could
be easily modified to use rtsp, but latency is critical for my particular
application (UAV).
The streams can easily be run with the gst-launch command printer out at
runtime.
I also added an option to explicitly run the program headless, as there are
potential use cases where you want both local display and streaming.
I tried to stick to the style of the code as much as possible.
I hope this is of use to other people, and many thanks to the authors for
this great application.
If there are any modifications (probably many) which you would like to see
before inclusion, please let me know!

Should be enhancement, but don't think I can change myself.

Currently, the patch needs to be built against OpenCV 2.0, or you will get a
warning
about cvEncodeImage being undefined.

This has been included into version 1.042. I've also added the openCV 2.0
package as
a download.
