try adding the -v , -e , --gst-debug=0 "flags". for example : gst-launch v4l2src -v --gst-debug=0 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 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 <mazahir.poonawalla at ideaforge.co.in> > 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.
