v4l2src and dynamic image/jpeg

It is probably a basic question but I didn't find a good answer.
I'm trying to write a Bin that it is something like:
v4l2src ! capsfilter! vaapijpegdec ! srcpad
I would like to add and remove jpeg decoder if my target resolution
requires image/jpeg or x-raw.
For example, I have some camera that provides image/jpeg and other that
How can I approach this problem?
Should I configure the caps filter with image/jpeg and I420 and use a probe
query_downstream/upstream to dynamically link/remove the jpegdec?
There is a simpler approach for that?

it so simple that there are obviously no deficiencies, and the other way is
to make it so complicated that there are no obvious deficiencies. The first
method is far more difficult.”
