August'24: Kamaelia is in maintenance mode and will recieve periodic updates, about twice a year, primarily targeted around Python 3 and ecosystem compatibility. PRs are always welcome. Latest Release: 1.14.32 (2024/3/24)
Cookbook Example
How can I...?
Example 4: Building a very simplistic multicast based streaming system using ogg vorbis. Components used:component, ReadFileAdaptor, VorbisDecode, AOAudioPlaybackAdaptor, Multicast_transceiver, pipeline
