Icecast is a Free and Open Source multimedia streaming server, primarily used for audio and radio streaming over HTTP(S).
In GStreamer you can send an audio stream to such a server with the
shout2send sink element based on libshout2.
This works perfectly fine, but has one limitation: it does not support the AAC audio codec, which for some use cases and target systems is the preferred audio codec. This is because libshout2 does not support it and will not support it, at least not officially upstream.
Some streaming servers such as the Rocket Streaming Audio Server (RSAS) do support this though, and as such it would be nice to be able to send streams to them in AAC format as well.
Enter icecastsink, which is a new sink element written in Rust
to send audio to an Icecast server.
It supports sending AAC audio in addition to Ogg/Vorbis, Ogg/Opus, FLAC and MP3, and also has support for automatic re-connect in case the server kicks off the client, which might happen if the client doesn't send data for a while.
Give it a spin and let us know how it goes!
