 In production environments image sequences are often generated with the
 frame number being based on time code. For example, in a 24 fps timeline,
 where picture start is at 00:59:52. The fist numbered frame would be
 fname.086208.dpx ((59*60+52)*24)

 In order to use ffmpeg the files would either have to be renamed, linked,
 or a clever script be written to handle the renumbered sequence.

 Looking at the code it appears the img2.c the function find_image_range
 could be adjusted to better detect image ranges.
