Note that both v4lsrc and v4l2src are similar in this area. Although this
suggestion (to use pad_alloc) sounds simple, unfortunately it is not. These
elements do not allocate buffers for each frame, but rather maintain their own
pool (this is primarily due to the need for the data part of the buffers to
have been "mmap'ed", because they are also directly used by the associated
driver).

Since "downstream-allocated" buffers would seem to not be a viable option in
this instance, is there any other suggestion as to how the required change in
caps should be recognized by the v4l(2)src elements?
