Coming up next - another new subtitle filter:

- split_cc (V -> VS)
  Extract closed-captions from AV_FRAME_DATA_A53_CC side 
  data as subtitle stream
  (input0: video, output0: video(passthrough), output1: subtitles[text])


Under consideration:

- rearrange_subtitlerects (S -> S)
  Move subtitle bitmap rects constrained to a certain area
  For fitting graphical subs into a target area without scaling

- sscale (S -> S)
  Scale subtitle bitmap rects
