Gstreamer Application

[Giritharan]

Hi i wrote gstreamer applicaton to record video along with audio for the
following gstreamer command.
*

gst-launch –e mfw_v4lsrc capture-mode=0 fps-n=30 ! vpuenc codec=0 ! queue !
mux. alsasrc ! 'audio/x-raw-int,rate=48000,channels=1' ! mfw_mp3encoder !
queue ! mux. avimux name=mux ! filesink location=audio_video2.avi
sync=false.

so my problem is while running the below c file i got the output like
(MFW_GST_V4LSRC_PLUGIN 3.0.7 build on Nov  6 2014 19:28:40.
