Is there a way to set the segment index start number in hlssink2

I’m using hlssink2 in GStreamer (gst-launch-1.0 and in code) to generate HLS segments, and I need the .ts segment filenames to start from a specific index — for example:

segment_1200.ts, segment_1201.ts, ...

This is required because the HLS playlist is being fed into Jellyfin (I’m developing a ffmpeg wrapper script) that expects segment numbering to match the media timeline, when starting from a seek offset (e.g., 1 hour and 3 seconds HLS segment duration→ segment 3600 / 3 = 1200).

I’ve tried formatting the location string like segment_%d.ts, but I couldn’t find any parameter like start-index in hlssink2.

Is there a supported way to:

  • Offset the segment numbering?
  • Or modify the numbering logic in hlssink2?

If not, are there any recommended workarounds?

Thanks in advance!
