tiovxldc not modifying input

[m-herrera]

The following pipeline does not affect the input although the openvx graph is indeed processing.

gst-launch-1.0   \
videotestsrc is-live=true num-buffers=10 ! video/x-raw,width=640,height=480,format=NV12 !   \
tiovxldc dcc-file=/opt/imaging/imx390/dcc_ldc_wdr.bin sensor-name=SENSOR_SONY_IMX390_UB953_D3 !    \
filesink location=/tmp/ldc_rectified.raw

The same behavior is seen when using the modules.
This happens in SDK 8.1
