Updated series that includes the change requested by Lance Wang and
the fate test reported by Michael Niedermayer.  Also includes a fix for
a 58-byte memory leak on uninitialization detected via valgrind while
debugging the fate issue.

Devin Heitmueller (6):
  ccfifo: Properly handle CEA-708 captions through framerate conversion
  vf_fps: properly preserve CEA-708 captions
  yadif: Properly preserve CEA-708 closed captions
  tinterlace: Properly preserve CEA-708 closed captions
  vf_ccrepack: Add new filter to repack CEA-708 side data
  decklink_enc: add support for playout of 608 captions in MOV files
