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 updated to add a time_base field to the new side-data
type, as well as various improvements suggested by Andreas Rheinhardt
to the BSF filter.

Devin Heitmueller (5):
  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
  mpegtsenc: Don't periodically announce PCR on SCTE-35 streams
  bsf: Add new bitstream filter to set pts_adjustment when reclocking
