 Summary of the bug:

 Sorry, unable to append gdb output. Followed the instructions, didn't work
 for me. ???

 I'm creating a video from jpegs. This has never failed for me. Always
 works.

 Today, I'm using really crappy input, i.e. the jpegs are not all of
 uniform height and width, so I was expecting a problem.

 But I did not expect ffmpeg to DESTROY the input files.

 So, I'll correct my input files and re-run. No problem.

 But I wanted to give you guys the heads up! on this.

 No way should the input files ever be overwritten.

 How to reproduce:

 1. Unzip the attached files (bunch of very small jpegs).

 2. Then run the command below


 {{{
 % ffmpeg -y -i 00/* -r 25 result.mp4

 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
