Audio streaming via Nimble Streamer
Nimble Streamer supports various audio codecs
Icecast/SHOUTcast processing
Icecast or SHOUTcast may be taken as input for further transmuxing.
- Icecast can be published into Nimble Streamer
- Icecast streams may be taken via public HTTP URL.
- Multiple pulled Icecast streams can also be used as a fallback for robust streaming.
- Failover for published Icecast streams can be set using hot swap.
Output protocols are Icecast, SRT, NDI, RTMP, RTSP, MPEG-TS, HLS and MPEG-DASH.
Multiple protocols can be transmuxed into Icecast.
- Transmux RTMP to Icecast getting published and pulled RTMP
- Transmux RTSP to Icecast getting announced (pushed) and pulled RTSP
- Transmux MPEG-TS to Icecast getting MPEG-TS via HTTP and UDP
- Convert pulled HLS to Icecast
- Use SRT as input for Icecast
- Process NDI input into all supported protocols including Icecast.
- WebRTC WHIP ingest of Opus can be transcoded into Icecast output.
- ID3 tags are recorded into DVR if the Icecast or HLS source has them.
Watch this video tutorial to see the setup and basic usage of pulled Icecast streams.
