 Summary of the bug: i am converting image sequences to mov files.  my
 frames are in the format of : file.%04d.jpg.
 The numbering is 1379-2328.  With these frame numbers ffmpeg tells me :

 [image2 @ 000000000210f640] Could find no file with with path
 'Z:/job/myProject/prod/io/client/client_out/20120817/FROM_VENDOR/20120817/TO_EDITORIAL/jpg/IL208_070_V004_%04d.jpg
 ' and index in the range 0-4

 if i renumber the frames starting at frame 0001 then conversion happens
 perfectly.

 How to reproduce:
 {{{
 ffmpeg -i
 z:/job/projectName/prod/io/client/client_out/20120817/FROM_VENDOR/20120817/CINESYNC/1280x720/jpg/IL208_070_V004_CC.%04d.jpg
 -vcodec mjpeg -qscale 8 z:/output.mov
