Does webOS Web App Support UDP Multicast Streaming?

I’m building a web application for LG Smart TVs (webOS) focused on live TV streaming. The entire streaming setup is based on UDP multicast and I need to know if webOS web apps are capable of directly handling these streams.

I’ve tested using <video> and <embed> with udp:// as the source, but so far there’s no playback or error—just silence. I’ve seen conflicting info online, with some sources claiming webOS supports multicast, but it’s unclear whether this is limited to the native Live TV system or actually accessible within web apps.

Does anyone know for sure:

  • Can a web app running on webOS access and play UDP multicast streams?
  • If yes, what is the correct method or API to do so?
  • If no, is the only option to convert the stream to HLS (e.g., using VLC/FFmpeg externally) and play that instead?

Any insight or experience with this would be really appreciated. Thanks!
