AE library properties not working on ISP element

[emmadrigal]

When trying to change these to something other than the default value the library appears to not work. For example, see the number of skipped frames, see the following pipelines:

• ae-num-skip-frames=0

GST_DEBUG="*ti*:6" gst-launch-1.0 \
v4l2src device=/dev/video2 io-mode=5 ! "video/x-bayer, width=1920, height=1080, format=rggb, framerate=30/1" ! \
tiovxisp dcc-isp-file=/opt/imaging/imx219/dcc_viss.bin format-msb=7 \
sink_0::device=/dev/v4l-subdev2 sink_0::dcc-2a-file=/opt/imaging/imx219/dcc_2a.bin \
sink_0::ae-num-skip-frames=0 \
! kmssink

• ae-num-skip-frames=1

GST_DEBUG="*ti*:6" gst-launch-1.0 \
v4l2src device=/dev/video2 io-mode=5 ! "video/x-bayer, width=1920, height=1080, format=rggb, framerate=30/1" ! \
tiovxisp dcc-isp-file=/opt/imaging/imx219/dcc_viss.bin format-msb=7 \
sink_0::device=/dev/v4l-subdev2 sink_0::dcc-2a-file=/opt/imaging/imx219/dcc_2a.bin \
sink_0::ae-num-skip-frames=1 \
! kmssink

On the second pipeline, the sensor_out_data that TI_2A_wrapper_process returns is always stuck to the same value. This also behaves the same for the awb-num-skip-frames

The feedback itself to the ISP node appears to work correctly since the image doesn't have a green tint like we had when the AE library wasn't integrated.

And when trying to use this with multiple cameras, if one has a num-skip-frames=0 and the other num-skip-frames=1, the one with a value of 1 has the incorrect behavior. This error is not only with 1, is with any value other than 0.

Hi @s-jain1

Please take a look at this

Hello, dear developers,

FYI, in SDK11 it still does not work.
