Just re-compiled Cin-GG latest, and apparently new filter from ffmpeg 4.2 (I compiled with ffmpeg.git again)
was causing segfaults, so I commented it out in /usr/share/cin/ffmpeg/plugin.opts:  #freezedetect

Actually, I also commented out derain filter, because it need some other (neural net model?) file I don't have.

ffmpeg 4.2 also was released:
August 5th, 2019, FFmpeg 4.2 "Ada"
FFmpeg 4.2 "Ada", a new major release, is now available! Some of the highlights: 
tpad filter
AV1 decoding support through libdav1d
dedot filter
chromashift and rgbashift filters
freezedetect filter
truehd_core bitstream filter
dhav demuxer
PCM-DVD encoder
GIF parser
vividas demuxer
hymt decoder
anlmdn filter
maskfun filter
hcom demuxer and decoder
ARBC decoder
libaribb24 based ARIB STD-B24 caption support (profiles A and C)
Support decoding of HEVC 4:4:4 content in nvdec and cuviddec
removed libndi-newtek
agm decoder
KUX demuxer
AV1 frame split bitstream filter
lscr decoder
lagfun filter
asoftclip filter
Support decoding of HEVC 4:4:4 content in vdpau
colorhold filter
xmedian filter
asr filter
showspatial multimedia filter
VP4 video decoder
IFV demuxer
derain filter
deesser filter
mov muxer writes tracks with unspecified language instead of English by default
added support for using clang to compile CUDA kernels
 We strongly recommend users, distributors, and system integrators to upgrade unless they use current git master.
