I have few doubts on SCTE-35 markers.

  1. Is there any open source tools available to add splice points to mpeg segments. Currently I am using mpddash and mp4hls for converting fragmented mp4 into mpd/hls. Please help where and how can I add SCTE markers.
  2. Can I add SCTE markers to mp4 file?
  3. As per my understanding, to dynamically add advertise a content segments must have some splice points previously added to it. With the help of an ESAM script the splice points are replaced with actual advertise with a live transcoder. Please correct me if I am wrong.

In SCTE 35 standard it is mentioned to splice_insert() etc. commands. Is there any tools available where these commands can be applied to mpeg segments?

In short I want to understand, how can I add scte 35 markers to vod content?

    I don't know of a DASH or HLS tool but this one exists for MPEG TS streams: https://github.com/tsduck/tsduck. You can use packagers like AWS Media Package and Unified Streaming etc to insert them also and you can usually get a trial version or account to try it out on. – Mick Oct 10 '22 at 16:26

Currently SCTE-35 does not have a way be insert into mp4 files, however SCTE-35 cues can be inserted in Dash and HLS with fragmented mp4 segments.

For MPEGTS streams, SuperKabuki does SCTE-35 packet insertion.

For HLS umzz injects SCTE-35 into HLS even Live HLS.
