Let’s say I have ffmpeg running with an overlay video filter.
Then I can use zmq to send a message to the overlay filter to change the
x option. Setting x to a very large number effectively disables the
overlay and setting x back to a value within my frame width brings back
the overlay. Is that correct?
The overlay filter has two inputs. Is there any way I can change the
input while the filter is running?
