It simply does not make sense to:
1.) grab the picture
2.) let the camera encode it
3.) receive it from v4l2
4.) decode it in camerabin
5.) apply effect
6.) encode it again

also its not straight forward to have alternative signal paths to support a
smart passthrough for the cases where no effect is selected (decoding still
needed for the viewfinder).

The last time we discussed the consesus was to not support this usecase.
Besides people can work-around the issue by using:
 LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so my-app

Although I don't yet see why:
gst-launch camerabin video-source="v4l2src ! decodebin2" is not working.
