Many proprietary Apple HTTP live streaming or other HTTP streaming
encoders accept SCTE 35 markers in the input MPEG stream. Using these
streams, these segmenters break the segments at the points described in
the SCTE 35 message. In addition to this, a comment is inserted into the
M3U8 manifest to indicate that the following chunk occurred after a SCTE
35 message.
This is now a very common practive, but no open source solution exists.
The great benefit of this is that it allows a downstream piece of software
to swap out chunks when such messages occur by simple text manipulation on
the manifest file. The most common use case for this is the insertion of
ads between 2 SCTE 35 messages in a live stream.
This is becoming a common feature in commercial encoders and it would be
great to see it land in ffmpeg.
