-loop option is specific to the image sequence demuxer. Without it, a
single image input is a video stream of 1 frame length.
You would apply loop when you need to keep alive an image sequence input
at a timestamp beyond its natural length, usually a fade.
With the tpad or loop filters, this can be done inside a filtergraph
instead of at the demuxer level.
