IP Streaming

MultiTuner can retransmit any monitored FM channel as a UDP MPEG-TS transport stream. Both multicast and unicast destinations are supported, and each channel can be streamed independently to a different destination.

Enabling Streaming for a Channel

Click the cloud icon on an active channel tile to open the streaming configuration for that slot.

Streaming setup

Configure the parameters and click Submit to apply:

Parameter Description
Destination address Multicast group address (e.g. 239.1.1.1) or a unicast IP address
Port UDP destination port
Bitrate Output audio bitrate for the transport stream
Enable streaming Check to activate streaming for this channel

Streaming status is shown on the channel tile in the main view — a highlighted cloud icon indicates the channel is actively streaming.

Multicast requirements

For multicast streaming, IGMPv2 must be enabled on your network switch. Use addresses in the valid multicast range: 224.0.0.0 – 239.255.255.255. The 239.x.x.x block is recommended for locally scoped multicast.

Receiving the Stream

Once streaming is active, the transport stream can be received by any software or hardware that supports UDP MPEG-TS input.

Stream capture in third-party software Example: capturing a MultiTuner transport stream in a third-party application

VLC Media Player

  1. Open Media → Open Network Stream
  2. Enter the stream address in the format: udp://@239.1.1.1:1234
  3. Click Play

FFmpeg

To record a stream to a file:

ffmpeg -i udp://239.1.1.1:1234 -c copy output.ts

To transcode to a different format on the fly:

ffmpeg -i udp://239.1.1.1:1234 -acodec mp3 output.mp3
