FFMPEG multiple file pattern not working in single command

问题

I want to add multiple file sequences in single ffmpeg command, below is my code, video is getting created but only first image sequence is getting used, second is getting ignored

ffmpeg -y -i input.mp4 -start_number 0000001 -i 1/%07d.png -i 2/%07d.png -filter_complex "[0][1]overlay=x=10:y=10:enable='between(t,0,3)'[v1];[v1][2]overlay=x=10:y=10:enable='between(t,3.8561422222222,6.9761777777778)'[v2]" -map "[v2]" -map 0:a out.mp4

Now the problem is FFMPEG wants continous images, which i don't have i have images starting from 0000001.png in each folder, how can i accomplish this without changing much in my images

回答1:

Try the glob pattern to deal with inconsistent numbering and pad the PTS with setpts so the overlay doesn't get consumed before it is displayed:

ffmpeg -y -i input.mp4 -pattern_type glob -i "1/*.png" -pattern_type glob -i "2/*.png" -filter_complex "[0][1]overlay=x=10:y=10:enable='between(t,0,3)'[v1];[2]setpts=PTS+3.856/TB[fg];[v1][fg]overlay=x=10:y=10:enable='between(t,3.8561422222222,6.9761777777778)'[v2]" -map "[v2]" -map 0:a out.mp4

Can you pipe the images to -f image2pipe ?

cat $(find 1 2 -name '*.png' -print) | ffmpeg -y -i input.mp4 \
-f image2pipe -vcodec png -i - \    
-filter_complex "[0][1]overlay=x=10:y=10:enable='between(t,0,3)'[v1];[v1][2]overlay=x=10:y=10:enable='between(t,3.8561422222222,6.9761777777778)'[v2]" \
-map "[v2]" -map 0:a out.mp4
