I'm new in using gstreamer on TI, and I meet some problems.
the follow is my commandline:
gst-launch-0.10 v4l2src always-copy=false num-buffers=200 i
nput-src=COMPOSITE ! video/x-raw-yuv,format=\(fourcc\)NV12,width=640,height=480
! tee name=d d.! queue ! ffmpegcolorspace ! video/x-raw-yuv,format=\(fourcc\)UYV
Y,width=640,height=480 ! TIImgenc1 resolution=640*480 iColorSpace=UYVY oColorSpa
ce=YUV420P qValue=75 engineName=codecServer ! filesink location=/usr/local/bin/o
utput.jpg d.! queue ! TIVidenc1 codecName=h264enc engineName=codecServer contigu
ousInputFrame=TRUE bitRate=2000000 framerate=25 rateControlPreset=2 ! avimux ! f
ilesink location=/usr/local/bin/test.avi
the error message is:

Additional debug info:

Trying to dispose element pipeline0, but it is in PAUSED instead of the NULL state.
You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.
This problem may also be caused by a refcounting bug in the
application or some element
what's the matter ?
thanks.
