This updated series includes fixes for feedback by Lance Wang, as well
as a second set of inject/extract functions that let you pass the
raw CC bytes as opposed to an AVFrame. This is used by the last
patch in the series to playout e608 packets with the decklink output.
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
