Hello,

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:

https://www.ridgerun.com/developer/wiki/index.php/LeopardBoard_365_GStreamer_Pipelines_-_SDK_2011Q2

http://designsomething.org/leopardboard/f/33/p/806/2827.aspx#2827

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:

Setting pipeline to PAUSED ...
davinci_resizer davinci_resizer.2: RSZ_G_CONFIG:0:1:124
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Cannot identify device '/dev/video0'.
Additional debug info:
../../../src/sys/v4l2/v4l2_calls.c(573): gst_v4l2_open (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
system error: No such file or directory
Setting pipeline to NULL ...
Freeing pipeline ...

This happens all the time. I restarted the leopardboard, also reinserted the sd card but it just does not work. 

Can anyone please suggest as to what is going wrong?

Thanks,

Maz
