fd1652b3ba Improve the fieldmatch documentation about mixed telecined content.
The fieldmatch filter has no problem with mixed telecined and
progressive content but the decimate filter does not detect the
changing framerate and drops progressive frames.

238ed47fae Mention in the documentation that fieldmatch needs cfr input.
This can be improved in the decimate filter but for the moment
explicitely mentioning that mixed telecined and progressive
content is unsupported is an improvement.

Fixes ticket #3968.

cec59eb63f avfilter/dctdnoiz: add 8x8 dct and make it the default
8x8 is about 5x faster than 16x16 on 1080p input. Since a block size of
8x8 makes the filter almost usable (time wise) and it's not obvious if
8x8 or 16x16 is better from a quality PoV (it really depends on the
input and parameters), the filter now defaults to 8x8, and as a result
libavfilter is micro bumped.
