 Dear ffmpeg team!

 This bug report shows a case when using the fps filter causes a video
 artifact to remain in the output for many more frames than it does without
 the fps filter.

 As input, you need the video "white-car.txt" which I have uploaded to the
 ftp server upload.ffmpeg.org .  This is a h264 video file, 5 megabytes in
 size, which has an error in it, probably because a frame or part of it was
 damaged when I have recorded the original from network.

 I have first played the video file with the following command:

 {{{ffmpeg -report -v 99 -i white-car.mkv -vsync passthrough -q 4
 d-%05d.jpg}}}

 The output is 183 image files.  On the output "d-00157.jpg", you can see
 serious artifacts, noticable for example if you compare the white car
 closest to the camera and the ground below it with the surrounding frames.
 On the following frame "d-00158.jpg" and frames after it, the artifacts on
 the car and the ground below mostly disappear, with only a little noise
 remaining.  (Some artifacts still remain on the upper half of the
 picture.)

 Now I have instead played the video with the following command, including
 an fps filter:

 {{{ffmpeg.exe -v 99 -report -i white-car.mkv -filter fps=25 -vsync
 passthrough -q 4 f-%05d.jpg}}}

 This creates 249 output files.  The artifact is visible on "f-00214.jpg"
 on the white car and the ground below.  However, most of the artifact on
 the door of the white car still remains in the output in all the following
 output images, unlike what I got with the previous command.  These aren't
 merely duplicate frames, because you can see the man in the upper half of
 the images walking.

 I believe this is a bug, because the fps filter should not cause an
 artifact to remain in the output for longer than it normally does.  The
 artifact could of course remain in the output for a few frames if the
 frame happens to be duplicated, but that is not the case here.

 For this test, I am using the Zeranoe ffmpeg build on Windows x64, version
 ffmpeg-20141120-git-4388e78-win64-shared.  The rest of the ticket shall
 show the full report output from the two commands.
