On Windows 2000 SP4, Standard 486+ Build, when trying to encode an Xvid video in QCIF format@15 fps, I get an Integer Division by zero error. The conversion script is as follows (Batch file):

REM MPEG-4 Simple Profile L0
del foreman_MPEG4_SP@…
mencoder ..\..\uncompressed\foreman_qcif@… -o foreman_MPEG4_SP@… -of rawvideo -ovc xvid -xvidencopts pass=1
mencoder ..\..\uncompressed\foreman_qcif@… -o foreman_MPEG4_SP@… -of rawvideo -ovc xvid -xvidencopts bitrate=64:pass=2:profile=sp0
..\mp4box\MP4Box -fps 15 -add foreman_MPEG4_SP@… foreman_MPEG4_SP@…

Version used: MEncoder Sherpya-SVN-r31878-4.2.5 (C) 2000-2010 MPlayer Team, This bug was also present in earlier versions also.

I am adding the video i am trying to convert as attachment, it is over 16 Mbytes in size though.

The attachment failed because of the size, but the video file I was using was :

foreman_qcif@… encoded in 24-bit RGB format, with a resolution of 176x144 @ 15 fps. I can upload it somewhere it if you need it for debugging purposes, just let me know where.
