"REMOTEIP" in capture_stream_udp.py is correct?

[baqwas]

Hello,

The following statement on line 16 in capture_stream_udp.py raises an error for "REMOTEIP". Is this string a placeholder for an IP address? Thanks.

Regards.

Yes, as the name says the IP address of the computer to which you send the stream

Thanks, @tvoverbeek!

So how would I go about doing a multicast, please? I gotten this far only!

        # set the socket to multicast mode
        sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        sock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, 255)
        
        # join the multicast group
        multicast_request = socket.inet_aton("224.0.0.1")
        sock.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, multicast_request + b'\0')
        
        # send camera output?
        sock.sendto(???, ("224.0.0.1", 10001))
        
        stream = sock.makefile("wb")
        
        picam2.start_recording(encoder, FileOutput(stream))
        time.sleep(20)

Not sure how to make picamera2 use the multi-cast (attempt on my part). Thanks again.

Regards.
