I have attached a patch for gsd_img_mpeg.c (ogsf) which is based on the
later releases of ffmpeg (output_example.c). This uses a function
guess_format to guess the format based upon the file extension given. If
the format is unknown it reverts to mpeg1. With this patch you can save
to any (almost) format supported by ffmpeg. For example you can save to
asf, avi, flv, swf, etc. To use this with nviz the auto name extension
in panel_kanimator.tcl will have to be commented out ...

#       if { [string compare $fnameExt ".mpg"] != 0  &&
#               [string compare $fnameExt ".mpeg"] != 0 } then {
#           append keyanimBaseName ".mpg"
#       }

The patch needs testing, etc. 

Let me know if you have any questions.
