streaming with leopardboard dm365

Hi,

I am new to leopardboard and gstreamer. I want to stream live video over network. I have tried every possible plugin examples available (in the links below) but none of them are working.

Can anyone please help. I am using the LI-5M03 camera headboard to capture. Also the board and machine is connected directly through static ip and linux machine is installed on virtualbox. Could this cause a problem?

Will appreciate the help.

Thanks,

Maz
