Ffmpeg scene overlay not working as intended
3 avril 2020, par BertgramI simply want to use scene detection on a video, retrieve thumbnails, tile them and overlay them over a solid background. However the tiled thumbnails are not showing up. The solid background shows blank.



Here is my code :



ffmpeg -f lavfi -i color=c=red:s=640x480:d=0.5 -ss 00:00:10 -i "input.mp4" \
-filter_complex "[1]select='gt(scene\,0.4)', scale=100:100, tile=3x3 [overlay]; \
[0][overlay]overlay=0:100" -frames:v 1 -y output.png




When I change scene detection to select='not(mod(n\,100))' then it is working :



ffmpeg -f lavfi -i color=c=red:s=640x480:d=0.5 -ss 00:00:10 -i "input.mp4" \
-filter_complex "[1]select='not(mod(n\,100))', scale=100:100, tile=3x3 [overlay]; \
[0][overlay]overlay=0:100" -frames:v 1 -y output.png




What is wrong with my fist code that select scene statement is not working ?
