Subject: [FFmpeg-devel] [PATCH v2 2/5] mpegts: Stash original PTS for SCTE-35 sections for processing later
Date: Mon,  3 Jul 2023 14:15:06 -0400
Message-ID: <1688408109-14381-3-git-send-email-dheitmueller@ltnglobal.com> (raw)
In-Reply-To: <1688408109-14381-1-git-send-email-dheitmueller@ltnglobal.com>

We need the original PTS value in order to do subsequent processing,
so set it as packet side data.
