Description

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

That is the expected behavior.

Check image2 options start_number and start_number_range for sequences starting from an arbitrary index.
