I tried to export a keyframe animation to an mpeg file but I got this error:
Error: gsd_init_mpeg failed to initialize MPEG stream
while executing
"Ninit_mpeg $animBaseName"
(procedure "animRunAndSave" line 36)
invoked from within
"animRunAndSave .middle.panelarea.panels.animation"
invoked from within
".middle.panelarea.panels.animation.bottom.rands invoke"
("uplevel" body line 1)
invoked from within
"uplevel #0 [list $w invoke]"
(procedure "tk::ButtonUp" line 22)
invoked from within
"tk::ButtonUp .middle.panelarea.panels.animation.bottom.rands"
(command bound to event)
Thanks for any help

(PS when I'm not completely wrong, I'm running grass6.1.csv on cygwin)
so it's getting clear why it is not working ;-(( Is compiling NVIZ as difficult (for a beginner) as compiling Grass? What do I need do do? Or are there other ways to combine the rendered key frames to a movie?

gsd_init_mpeg() should write its own error messages to stderr; check
the terminal window for one of the following:
codec not found
could not open codec
Cannot open file for output

NVIZ will be compiled along with the rest of GRASS if the relevant
options are enabled. However, NVIZ has the most dependencies of any
GRASS component, so compiling GRASS with NVIZ may be more work than
compiling without it.
What do I need do do? Or are there other ways to combine the
rendered key frames to a movie?
You can output a series of images then generate a movie using a
stand-alone encoder such as ffmpeg.
Does anybody know the exact syntax for
--with-ffmpeg-includes=/usr/include/ffmpeg, and which packages should be
included? In Debian testing I could not find an ffmpeg-dev package, and thus
I do not have /usr/include/ffmpeg.
Thanks.

I also never built Grass on my own! I just use the installer from cygwin, but this is a binary package. Building grass on cygwin seems for me even more complex than on a native linux system.

PS. I have the same problem with building the new v.in.dxf. Probably I habe to wait for a binary release where these functions are included.

thanks for clarifying this. do you remeber the name of the deb package
for ffmpeg? I found only ffmpeg (no -dev package, thus no /usr/include).
$ apt-file search /usr/include/ffmpeg/
#libavcodec-dev # for FFMPEG support
libavcodeccvs-dev# for FFMPEG support
libavutilcvs-dev # for FFMPEG support
