Maz - looks like your video device node is not created, verify the camera connection to the board and then the camera driver.

TIVidenc1 codecName=h264enc engineName=codecServer ! avimux ! filesink location=sample.h264 or ar the other end of v4l2src , like in this example gst-launch -v -e --gst-debug=0 v4l2src always-copy=false num-buffers=100 ! video/x-raw-yuv,width=640,height=480,framerate=25/1 ! TIVidenc1 codecName=h264enc engineName=codecServer ! avimux ! filesink location=sample.h264 this may help..not logical, but it works for me, on a different embedded device. 2012/7/31 Mazahir Poonawalla <[email protected]<mailto:[email protected]>> 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/TVP5146_GStreamer_example_pipelines 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?
