gstreamer video device not found

[Mazahir Poonawalla]

Hi,

I tried running an example plugin on leopardboard:

gst-launch -v -e v4l2src always-copy=FALSE input-src=composite
chain-ipipe=true ! video/x-raw-yuv,format=\(fourcc\)NV12, width=1280,
height=720 ! queue ! dmaiaccel ! dmaienc_h264 encodingpreset=2
ratecontrol=2 intraframeinterval=23 idrinterval=46 targetbitrate=3000000 !
rtph264pay ! udpsink port=$PORT host=$HOST_ADDR sync=false
enable-last-buffer=false

I also tried the example mentioned in
www.ridgerun.com/.../LeopardBoard_365_GStreamer_Pipelines_-_SDK_2011Q2<https://www.ridgerun.com/developer/wiki/index.php/LeopardBoard_365_GStreamer_Pipelines_-_SDK_2011Q2>
 :

gst-launch -e v4l2src always-copy=FALSE input-src=composite
chain-ipipe=true ! video/x-raw-yuv,format=\(fourcc\)NV12, width=1280,
height=720, framerate=\(fraction\)23/1 ! queue ! dmaiaccel ! dmaienc_h264
encodingpreset=2 ratecontrol=2 intraframeinterval=23 idrinterval=46
targetbitrate=3000000 ! rtph264pay ! udpsink port=$PORT host=$HOST_ADDR
sync=false enable-last-buffer=false &

But I keep getting the error as below:

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 ...

Can someone please help as to what is going wrong?
