For input that cannot be auto-detected, the file suffixes "jpeg" and "png" (and several others) imply the image2 demuxer which in turn is the only demuxer that understands the "%d" syntax. Since "img-%03d.jpeg" is not a file that can be auto-detected, the file suffix will be used to identify the image2 demuxer. Note in addition that the image2 demuxer is one of the few demuxers that does not support auto-detection but only works through file suffixes. There are specific demuxers for jpeg, png and several others that do support auto-detection (but not the "%d" syntax). I hope this helps, I will close your ticket (and try to explain there).
