I am trying to run gstreamer examples for composite video input as well as for input from LI-5M03 board as mentioned in the following web-pages:</p><p style="text-align:left;color:rgb(51,51,51);font-family:Arial;font-size:12px">

<p style="text-align:left;color:rgb(51,51,51);font-family:Arial;font-size:12px">The problem is that it runs the 1st time perfectly. But then when I try to run the 2nd time, I get the following error:</p>

This happens all the time. I restarted the leopardboard, also reinserted the sd card but it just does not work. </p><p style="text-align:left;color:rgb(51,51,51);font-family:Arial;font-size:12px">
Can anyone please suggest as to what is going wrong?</p><p style="text-align:left;color:rgb(51,51,51);font-family:Arial;font-size:12px"><br>Thanks,</p><p style="text-align:left;color:rgb(51,51,51);font-family:Arial;font-size:12px">
