[FFmpeg-user] ffmpeg ignores duration and skips concat images

Hello:
ffmpeg seems to be using only about 60 of 1500 image files in
creating a 1 minute video with the following command:
ffmpeg -y -r 1 -i restrictSecrecy3.mp2^
-f concat -i framesFiles.txt^
-vf fps=1 -pix_fmt yuv420p restrictSecrecy.mp4
The audio (restrictSecrecy3.mp2) plays fine in the output
(restrictSecrecy.mp4), but the video does not flow. "framesFiles.txt"
contains 3000 records, the first 4 of which are as follows:
file 01-00001NSA.png
duration 0.04
file 01-00002NSA.png
duration 0.04
Below please find the output generated using ffmpeg version
N-61620-ge555e1b under Windows 7. The inputs are available at
"https://drive.google.com/folderview?id=0B1bTqmKWlWxhaEFWRlVhekk5M2M&usp=sharing".
Thanks for your consideration.
Best Wishes,
Spencer Graves
