The HTTP Streamer can be enabled via the _streamer_enabled_ daemon parameter. When the Streamer is active the daemon starts capturing the configured _Sinks_ up to the maximum number of channels configured by the _streamer_channels_ parameters. The captured PCM samples are split into _streamer_files_num_ files of _streamer_file_duration_ duration (in seconds) for each sink, compressed using AAC LC codec and served via HTTP. The HTTP streamer requires the libfaac-dev package to compile. Please note that since the HTTP Streamer uses the RAVENNA ALSA device for capturing it's not possible to use such device for other audio captures.
