Unlike other cases where the closed captions are embedded in the

Various deinterlacing modes have the effect of doubling the
framerate, and we need to ensure that the caption data isn't
duplicated (or else you get double captions on-screen).

The existing implementation made an attempt to remove duplicate
captions if increasing the framerate, but made no attempt to
handle reducing the framerate, nor did it rewrite the caption
payloads to have the appropriate cc_count (e.g. the cc_count needs
to change from 20 to 10 when going from 1080i
When transcoding video that contains 708 closed captions, the
caption data is tied to the frames as side data. Simply dropping
or adding frames to change the framerate will result in loss of
data, so the caption data needs to be preserved and reformatted.

This latest update to the patch series includes several fixes from
Lance Wang to the vf_ccrepack, as well as incorporating feedback
from Anton Khirnov.
The primary change across all the filters was to make the filter error

av_mallocz_array is not present into libavutil/mem.c and libavutil/mem.h.
