Comment:
ok, if mid-stream changing of size is unsupported, then this ticket makes
no sense and can be closed. But it would be helpful to add a remark to the
documentation of the zmq filter:
It's possible to send zmq messages to all options of all filters. However,
not everything that's possible is also useful. For example, a zmq message
can be sent to the "scale" filter to change the size of a video stream.
But mid-stream changing of size isn't supported by many other filters. In
some cases this may work, but in most cases it fails.
