Can Icecast/Shoutcast metadata be used to insert HLS SCTE-35 marker

Hi Softvelum-Team,

we have an Icecast stream with metadata as input and are looking for an HLS output with SCTE-35 marker at the positions when there is a change in the Icecast metadata.

The important topics:
- We would insert the duration of the marker into the Icecast metadata. It would have to be parsed from there and inserted in the SCTE-35 (CUE-OUT) markers.
- The Icecast metadata are inserted every 16000bytes (~60ms). We would expect the HLS segments to be cut of at the exact (60ms accurate) position. For Example: if we have 2sec segments and an ad is inserted after 500ms of the segment, HLS playlist should look like:


Thanks in advance!

Hello, Ingo.

To clarify, Nimble cannot parse Icecast markers or make triggering on Icecast metadata.
Do you use any other solution that supports such a scheme?

Thank you.

Hi Sergei,

thanks for the reply. We do not have such a solution today (and i also could not find anything in the internet that could help). Nevertheless, if we would write our own Icecast parsing service would there be a Nimble interface that we could trigger (e.g. REST or Config) to set the SCTE-35 marker?

Thanks, Ingo

Hello, Ingo.
You may try to insert SCTE-35 tags via Nimble API call as described on the following documentation page:

Thank you.
