[FFmpeg-user] Change filters in running process without restarting it

[Maxim Kozlov]

I home it will be my last question about zmq.
I don't understand manual, how to bind it to another port?
manual: The zmq and azmq filters work as a libzmq server, which receives
messages sent through a network interface defined by the bind_address
option.

setting
-vf zmq="bind_address=localhost:5556",hue
thows error:
[Parsed_zmq_0 @ 0x1ed4660] No option name near '5556'
[AVFilterGraph @ 0x1ede8a0] Error initializing filter 'zmq' with args
'bind_address=localhost:5556'
