 Summary of the bug: star_number not working
 How to reproduce: I have a number of image files I want to convert into a
 ProRes video. Image files are named "slowDownX4_02699.tif" up to
 "slowDownX4_03030.tif".
 {{{
 "C:\Program Files (x86)\ffmpeg\bin\ffmpeg.exe" -framerate 24 -f image2 -i
 "slowDownX4_%%05d.tif" -start_number 2699 -vcodec prores -profile:v 3 -an
 "slowdownX4.mov"

 ffmpeg version 3.2.2
 built of download is ffmpeg-20161230-6993bb4-win64-static

 Error: Could find no file with path 'slowDownX4_%05d.tif' and index in the
 range 0-4
 slowDownX4_%05d.tif: No such file or directory
 }}}
 The call produces an error. If I rename the tif files to start at 00000
 and leave out the start_number parameter everything works as expected.
 I also tried different formats, names in small caps, less digits, higher
 start_number and more, but the problem stays the same.

 Complete output:
