e4788e9cd9 avfilter/vf_yadif: fix extra leading dup frame when deint=1 
Logic for handling single frame in yadif (0f9f24c9), caused deint=1 (e.g., yadif=0👎1) to output extra duplicate leading frame:

ffmpeg -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm  -vf yadif=0👎1,showinfo -f null -y /dev/null
 [Parsed_showinfo_1 @ 0x1d967d0] n:0 pts:0 pts_time:0 pos:-1 fmt:gray sar:0/1 s:352x432 i:P iskey:1 type:I checksum:E457EEA0 plane_checksum:[E457EEA0] mean:[126] stdev:[46.6]
 [Parsed_showinfo_1 @ 0x1d967d0] n:1 pts:0 pts_time:0 pos:-1 fmt:gray sar:0/1 s:352x432 i:P iskey:1 type:I checksum:E457EEA0 plane_checksum:[E457EEA0] mean:[126] stdev:[46.6]
(Outputs 51 frames)

After patch, vf "yadif=0👎1" behaves correctly (like "yadif=0👎0") and outputs 50 frames, first two:

[Parsed_showinfo_1 @ 0x1e307d0] n:0 pts:0 pts_time:0 pos:-1 fmt:gray sar:0/1 s:352x432 i:P iskey:1 type:I checksum:68E8D1EB plane_checksum:[68E8D1EB] mean:[126] stdev:[46.0]

dd5d617956 avfilter/vf_idet: Fixing idet for single-frame inputs. 
Handle single frame inputs similar to yadif (e.g., 0f9f24c9cf and 681e008d06)

Example:
  ffmpeg -r 1 -t 1 -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm  -vf idet,showinfo -f null -y /dev/null

Previously:
  Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)
  [Parsed_idet_0 @ 0x36389d0] Repeated Fields: Neither:     0 Top:     0 Bottom:     0

After patch:
  [Parsed_showinfo_1 @ 0x1909810] n:0 pts:0 pts_time:0 pos:-1 fmt:gray sar:0/1 s:352x432 ...
  [Parsed_idet_0 @ 0x18f9bb0] Repeated Fields: Neither:     1 Top:     0 Bottom:     0

ad5c43bb36 avfilter/vf_idet: Fixes issue with idet not flushing last frame. 
Uses a similar approach as vf_yadif to flush the last frame in idet.

Quick test with 50 frames from vsynth1:
./ffmpeg.old -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm -vf idet -f mp4 -y /dev/null 2>&1  | grep Multi
 (gives) [Parsed_idet_0 @ 0x261ebb0] Multi frame detection: TFF:0 BFF:0 Progressive:48 Undetermined:1

./ffmpeg -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm -vf idet -f mp4 -y /dev/null 2>&1  | grep Multi
 (gives) [Parsed_idet_0 @ 0x35a0bb0] Multi frame detection: TFF:0 BFF:0 Progressive:49 Undetermined:1

Fate tests have been updated.

(In testing, it seems this filter will also need a subsequent patch for single frame input)

6cbbf0592f resample: Avoid off-by-1 errors in PTS calcs. 
The rounding used in the PTS calculations in filter_frame() does
not actually match the number of samples output by the resampler.
This leads to off-by-1 errors in the timestamps indicating gaps and
underruns, even when the input timestamps are all contiguous.

aade9884e9 lavfi/apad: fix logic when whole_len or pad_len options are specified 
In particular, allow pad_len and whole_len to have value set to 0, which
means that no padding will be added. Previously a value set to 0 meant
that that the filter had to pad forever.

The new semantics is clearer, also simplifies scripting since the option
value might be automatically computed, so that no checks need to be done
in case it is 0.

The old semantics was never documented and the logic was broken (the
filter was always adding samples indefinitely), so this should not break
backward compatibility.

It is always identical to the last pushed frame.

this is unchanged.
Possible enhancement: pad the last incomplete window with
silence.

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.

The DCT factorization is based on "Fast and numerically stable
algorithms for discrete cosine transforms" from Gerlind Plonkaa &
Manfred Tasche (DOI: 10.1016/j.laa.2004.07.015).
