Properly set up the MPEG-TS mux and recalculate the pts_adjust field
in SCTE_35 packets, such that a user can transparently pass through
SCTE-35 streams when both the input and output are MPEG-TS.
This patch series rebased against master and a patch to hack around
periodic PCR retransmission has been dropped as the behavior is
no longer reproducible in master.
Devin Heitmueller (4):
avcodec: Add new side data type to contain original PTS value
mpegts: Stash original PTS for SCTE-35 sections for processing later
mpegtsenc: Add support for output of SCTE-35 streams over TS
bsf: Add new bitstream filter to set SCTE-35 pts_adjustment when
reclocking
