DRA72XEVM: gstreamer textoverlay in pipeline shows error.

Part Number: DRA72XEVM

Hi,

So i am facing an issue with gstreamer pipeline. The pipeline is as follows:

gst-launch-1.0 --gst-debug=3 -e rtspsrc location = "rtsp://admin:password@192.168.15.51:554/cam/realmonitor?channel=1&subtype=1" ! rtph264depay ! h264parse ! decodebin ! textoverlay text="sam" ! fakesink

On executing, the above pipeline throws a continuous error like

    Hi Sam,
    What is the issue you are seeing from this error? Are you not able to see the decoded video?
    Please insert vpe element with a caps filter and give a try.

    h264parse ! ducatih264dec ! vpe ! 'video/x-raw, format=(string)NV12, width=(int)1280, height=(int)720' ! textoverlay text="sam" ! fakesink
    This should work. Let me know the results

    HI Sam,
    Why do you want to have --gst-debug set ? Some warnings will be always printed with the debug option set but there is no harm

    Thanks,

    Just to be on safe side. Sometimes it may create issues while converting the command to a c file.
    Thanks once again.

    Regards,
    Sam
