[FFmpeg-devel] [PATCH] avformat/mpegts: Passthrough SCTE 35 Current behavior breaks SCTE 35 by wrapping it in a PES packet, this adds the logic for the SCTE 35 messages to be passed through cleanly.

[Pierre Le Fevre]

Hi Devin,
I saw your patch but noticed it was still not merged. Since it’s more comprehensive, I’m all for merging your patch instead of mine if it’s not too stale.

Best,
Pierre

For what it's worth, I submitted a similar patch series a couple of
years ago, which also accommodates modifying the pts_adjust field
(which is mandatory if the output stream's clocks are rebased).
