https://www.ffmpeg.org/ffmpeg-protocols.html#zmq
3.45 zmq
ZeroMQ asynchronous messaging using the libzmq library.
This library supports unicast streaming to multiple clients without
relying on an external server.
The required syntax for streaming or connecting to a stream is:
zmq:tcp://ip-address:port
Example: Create a localhost stream on port 5555:
ffmpeg -re -i input -f mpegts zmq:tcp://127.0.0.1:5555
Multiple clients may connect to the stream using:
ffplay zmq:tcp://127.0.0.1:5555
Streaming to multiple clients is implemented using a ZeroMQ Pub-Sub
pattern. The server side binds to a port and publishes data. Clients
connect to the server (via IP address/port) and subscribe to the
stream. The order in which the server and client start generally does
not matter.
ffmpeg must be compiled with the –enable-libzmq option to support this
protocol.
Options can be set on the ffmpeg/ffplay command line. The following
options are supported:
pkt_size
Forces the maximum packet size for sending/receiving data. The default
value is 131,072 bytes. On the server side, this sets the maximum size of
sent packets via ZeroMQ. On the clients, it sets an internal buffer size
for receiving packets. Note that pkt_size on the clients should be equal
to or greater than pkt_size on the server. Otherwise the received message
may be truncated causing decoding errors.
It doesn't seem to be specifically related to the fifo as the input:
