Hello all,

I am trying to implement a clock overlay to a video source from an analogue camera attached to the e-CAMNT_MX53x decoder board. The video is streamed and recorded in mp4 format, I followed the below procedure.

1,Enabled pango in the board.

2,Passed the command

     gst-launch-0.10 -v mfw_v4lsrc device=/dev/video0 capture-width=720 capture-height=576 sensor-width=720 sensor-height=288 typefind=1 preview=1 preview-width=1024 preview-height=768 bg=1 fps-n=25 fps-d=1 ! clockoverlay halign=left valign=bottom xpad=20 ypad=20 time-format="%R %d-%b-%Y" font-desc="Sans 15" shaded-background=false ! tee name=t ! queue ! mfw_ipucsc ! mfw_vpuencoder codec-type=std_mpeg4 ! avimux ! filesink location=/mnt/floppy/capturetest.mp4 t. ! queue ! mfw_v4lsink &

the gstreamer halted by giving the following warning WARNING: erroneous pipeline: could not link mfwgstv4lsrc0 to clockoverlay0

the command works fine if the clock overlay part is removed (i.e recording and streaming are proper).
