- Multicast enables efficient content distribution by delivering packets to multiple recipients simultaneously using reverse routing tables.
- Using live TV as an example, multicast can significantly upgrade home networks for niche use cases like streaming without excessive bandwidth.
- Basic file streaming without transcoding saves CPU by directly copying audio/video tracks into an MPEG-TS stream via FFmpeg.
- Transcoding may be necessary for less common media formats, using x264 and AAC to repack into MPEG-TS with FFmpeg.
- Routed multicast with source-specific multicast allows spanning subnets or VLANs, avoiding complex rendezvous points.
- FRR configuration enables IPv6 PIM and MLD for multicast routing, including access lists to filter groups and sources.
- Streaming over routed multicast requires setting a hop limit (similar to IPv4 TTL) in the UDP output options.
