 Summary of the bug:

 I am trying to encode a large file containing raw video in a single file
 to jpeg images one file per image.  The encoding processes the first 274
 frames properly, then gives errors about "Invalid timestamps" and stops.

 This behavior is strange because the input is raw and does not explicitly
 contain timestamps.  The error seems to come up slightly after reading two
 gigabytes of input, which may be a coincidence because I have tested with
 only one image size.  The input is 2560x1024 pixel images in raw gbrp
 format (green blue red 24 bit per pixel plane interplaced), thousands of
 images concatenated in a single large file.  The output is jpeg images,
 one file per frame.

 As a workaround, I could use the input option -s 2 to set the frame rate
 of input explicitly, which appears to make the bug go away.  This should
 have no effect on the encoding because I use the -vsync passthrough option
 to write one input frame to exactly one output file, and the jpeg outputs
 include no timing information.

 I am using ffmpeg built for windows x86_64, dynamic build from
 ffmpeg.zeranoe.com, on a windows 7 system.  The bug does not seem
 exclusive to windows though, because I have met a similar error on amd64
 linux too.

 How to reproduce:

 Get the ffmpeg build from
 http://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-20130418-git-
 ee94362-win64-static.7z .

 Create some dummy input composed of all zeros, with the following command.
 {{{
 e:\ambrus\f\fgbg\tmp>perl -we "binmode STDOUT or die; print pack
 qq(x).(2560*1024*3) for 1..1700" > zeros.dat
 }}}
 Then run ffmpeg with the following command.
 {{{
 e:\ambrus\f\fgbg\tmp>mkdir tout & ffmpeg -report -v 9 -loglevel 99 -f
 rawvideo -pix_fmt gbrp -s 2560x1024 -i zeros.dat -vsync passthrough
 tout\out-%05d.jpg
 }}}

 This writes only 274 frames of output (tout\out-00001.jpg to
 tout\out-00274.jpg inclusive) and gives the invalid timestamp errors you
 can see near the end of the verbose log output that follows.

 Log output:
