FFMPEG : custom sequence input images

Question

I created a video from a set of images.

The command look like:

ffmpeg -i bg.jpeg -i img_%d.png -filter_complex overlay=5:H-h-5[b]-shortest testvid.mp         


        

Answer 1

You can use the concat demuxer with the custom sequence.

First, create a text file:

file 'img_0.png'
file 'img_1.png'
file 'img_1.png'
file 'img_2.png'
file 'img_1.png'
file 'img5.png'
file 'img_4.png'

Then run

ffmpeg -i bg.jpeg -f concat -r 25 -i list.txt -filter_complex "overlay=5:H-h-5" -shortest out.mp4

Edit: For PNG and most other image formats, r should be expressly specified to initialize a duration for each image entry in the list.
