Hi, first bug report so apologies if format not quite correct. If the server has 2 network cards, the 1st card for HLS output and the 2nd card for multicast input. However, at times, real-time applications misbehave and cause bursts, which impact overall traffic flow. The last byte of the address is always 0. In case of udp multicast ffmpeg binds to the default interface which will quite often be wrong on multihomed hosts. 2 address is a multicast address. Therefore a multicast router also has to increment the TTL. Updated FFMPEG. For Multicast UDP you just need FFMPEG or VLC encoder on the server side and 4 RPI with VLC or FFPlay on the client side HDMI to CAT5 converters will cost ~$100/150.
